The Toyota Tundra has been named the most American-made full-size pickup truck. 

Like with any truck, replacement parts are needed regularly; that goes for headlights too.

When the factory halogens burn out on a Toyota Tundra, it’s time to upgrade. And I recommend going for the 9003/H4 LED bulbs, as they’re brighter, whiter, and last longer.

For more than ten years, I’ve been testing car and truck headlight bulbs and can advise on the good vs. the bad.

I tested a stack of 9003/H4s and narrowed it down to three. The Firehawk 9003/H4 bulbs are my favorites.

I’ll follow those with a runner-up for best and a budget option.

It’s time to find out the best 9003/H4 LED headlight bulbs for a Toyota Tundra.

Important note
I don’t personally own a Toyota Tundra, however for this review I borrowed my friend’s Tundra to test the bulbs to see how they performed and worked.


Firehawk 2023 9003/H4 LED Headlight Bulbs

OVERALL BEST

OVERALL BEST

The Firehawk 2023 9003/H4 LED headlight bulbs are my pick for best overall Toyota Tundra headlight bulbs. They’re super bright and have excellent heat retention.

Advertised Specifications

Firehawk 2023 9003/H4 bulbs are made using Japanese Chips, containing 20,000 lumens a set and a claim of 500% brightness over halogens.

They deliver a super-focused beam pattern, which doesn’t dazzle other drivers and has no shadows or dark spots.

The Kelvin color is why I think LEDs are necessary. Factory halogens come in at 3,000K, which is amber/yellow. Firehawk 9003/H4 LED bulbs are 6000K cool white. This color makes objects in front of the truck appear with much more clarity.

For heat management, the bulbs are made from 40 pieces of aviation aluminum heat sinks, 2mm thickened red copper, and a 12,000 RPM silent turbofan. They’re only 31 watts each, so they don’t draw much power.

All of this should keep them cool. But does it? See my test results below.

Firehawk offers a 2-year warranty on these bulbs and claims 50,000 hours of use. I’m yet to see bulbs last that long, and other drivers agree.

They have a waterproof rating of IP68, which is the highest possible level. This is excellent news and means the truck can be driven in all kinds of wet, snowy, or foggy weather with no issues.

And they also fit perfectly in my friend’s Toyota Tundra. 

My Observations

Firehawk makes awesome-looking bulbs that really stand out. The red copper finish is unique and something that differentiates them from the competition. While you can’t see it once installed in your Tundra, it’s still a nice look.

There’s nothing overly sophisticated about the materials used; they appear pretty standard.

It’s a neat all-in-one item with a built-in CAN bus driver and an adjustable collar. This design makes it an easy fit for a Toyota Tundra; it’s just plug-and-play. Installation should be less than 10 minutes.

My only concern was the relatively small fan; I wondered if the fan was big enough to keep everything cool.

My Tests

To keep things uniform, I perform all tests in the same way. I positioned a lux meter 20 feet away from the bulbs. And I’m comparing these to standard factory-installed halogens.

Regular halogens have a lux rating of 725 in the projector test and 910 in the reflector test. 

How did the Firehawk 2023 9003/H4 bulbs compare? Exceptionally well!

I got an initial lux rating of 1,332 in the projector test. That’s almost double the brightness of halogens. 

Where I’m really impressed is that after 27 minutes (the average commute time in America), they dropped to only 1,172 lux, which is only 88%. That’s well above the average of 78% retention.

This tells me that these bulbs have excellent heat retention, which could lead to them lasting a lot longer.

In the reflector test, I got an initial output of 2, 280 lux, 250% brighter than halogens. Not 500% as advertised, but excellent enough for a Toyota Tundra’s headlights.

These bulbs also have an excellent beam pattern. The hot spot is low, which is a bonus. I observed some slight scattering at the top center and bottom left. Apart from that, the beam was clear and wide.

I observed 29 watts which, compared to the 31 advertised, is surprisingly close. Well done, Firehawk.

I had concerns as the fan area was so compact, but I needn’t have. After 27 minutes, the temperature of the unit was only 122°F. That’s fantastic heat management.

I’d expect these bulbs to last a long time, based on the heat retention and the very cool temperature.

What Other Drivers Are Saying

Over 5,000 drivers rate the Firehawk 2023 9003/H4 LED bulbs with an average of 4.4/5 stars.

What the drivers love the most is how bright they get, their satisfaction with the beam pattern, and how improved the visibility is from the Kelvin color.

Unsurprisingly, most state they don’t last 50,000 hours, and that’s ok; I feel this is a marketing claim from all the manufacturers.

Summing it Up

For a Toyota Tundra, I recommend upgrading factory halogens to the Firehawk 9003/H4 LED bulbs. They’re bright and have excellent heat management, so they should last a long time.

Pros
  • Plug and play
  • 20,000 lumens/set
  • Unique red copper finish
  • Perfect beam pattern
  • 6,000K Cool White
  • +500% brighter than halogens (advertised)
  • Best overall 9003/H4 LEDs
  • 50,000-hour lifespan
  • 62W per set
  • All-in-one unit
  • Built-in 12,000 RPM turbo cooling fan
  • Excellent heat management
  • IP68 Water resistant
  • 2-year warranty
Cons
  • May not last 50,000 hours

Sealight X2 H4/9003 LED Headlight Bulbs

BEST BUDGET

Worthy Contender

My runner-up for best replacement headlights for a Toyota Tundra are the Sealight X2 H4/9003 bulbs.

Advertised Specifications

Sealight makes great headlights, but its marketing department does like to push boundaries with the product’s specs. I tested these with my friend’s Tundra and they were excellent. 

These X2 H4/9003 bulbs are supposedly 20,000 lumens a set and 600% brighter than halogens. That’s a big claim. How correct is it? See my test results below.

The bulbs contain a cutting-edge LED chip that creates a seamless light output source, resulting in a higher beam accuracy.

The Kelvin color is 6,500 cool white; this should provide extra clarity on objects in front of the truck.

The bulbs are cooled by a 20,000 RPM turbofan and an intelligent temperature control chip. Apparently, each chip is 75 watts. However, my tests showed something wildly different.

The longevity claims get larger, Sealight states these will last 60,000 hours, yet it only provides a 1-year warranty.

One thing that bothers me is that I can’t find an IP rating anywhere. So I’m unsure how durable these headlight bulbs are.

My Observations

Marketing hype aside, these are excellent bulbs for the Toyota Tundra.

Upon opening the box, I found rubber gloves, zip ties, and double-sided tape to attach the external driver.

Sealight takes care in manufacturing its bulbs, and these are solid-looking ones. I like the added 

touch of its logo covering the fan.

The heat fan seems rather shallow, and just like the Firehawk, I was concerned about its efficiency.

The external driver is nice and compact, that’ll make installation into the Toyota Tundra fitting much easier.

My Tests

Does the product live up to the claims?

The Sealight X2 H4/9003 LEDs came up with an initial lux rating of 954 lux, 249 higher than halogens — 130% brighter. 

What is impressive, and coincidentally, the same as the Firehawks, is that after 27 minutes, they also dropped to 88%, 842 lux.

In the reflector test, I got an initial rating of 1,864 lux. So they’re definitely 200% brighter than halogens, but 600%? Not even close. 

After 27 minutes, they maintained 88% heat retention at 1,645 lux.

I love that the beam pattern had excellent coverage of the usual weak spot in the lower center. 

What I didn’t like was the very high cutoff, and I suspect these won’t extend as far down the road as others. The beam pattern was also a bit scattered on the upper and lower left sides.

I tested the wattage at only 34.8 per bulb, making me think 75 watts is the total per set, not each, as advertised. 

Just like the Firehawks, these bulbs also have excellent heat management. After 27 minutes, the main unit was only 113°F, and the driver was 123°F.

The heat retention could mean they will last a long time, but I doubt they’ll get to 60,000 hours.

What Other Drivers Are Saying

The Sealight X2 H4/9003 headlight bulbs have an overall rating of 4.6/5 stars; most Tundra owners love these headlight bulbs.

The positives are that they’re bright and have an excellent beam pattern.

As expected, they didn’t last 60,000 hours.

Summing it Up

As runner-up for best, the Sealight X2 H4/9003 headlight bulbs are efficient, have an excellent beam pattern, and great heat management. They’re just not as bright as the Firehawk bulbs.

Pros
  • Plug and play
  • 20,000 lumens/set
  • 6,500K Cool White
  • +600% brighter than halogens (advertised)
  • Excellent heat retention at 88%
  • Runner-up for best H4/9003 LEDs
  • 60,000-hour lifespan
  • 150W per set (advertised)
  • Compact external driver takes up less space
  • Built-in 20,000 RPM turbo cooling fan
  • IP68 Water resistant
  • 1-year warranty
Cons
  • Don’t last 60,000 hours as advertised

Fahren Forscher 9003/H4 LED Headlight Bulbs

BUDGET CHOICE

Best Budget

At less than $50 a pair, the Fahren Forscher 9003/H4 LED headlight bulbs are a cost-effective option for Toyota Tundra headlights.

Advertised Specifications

Fahren states its 9003/H4 headlight bulbs contain 12,000 lumens per set and are 300% brighter than halogens.

The chip emits a super-focused beam pattern providing a wider and farther lighting range.

Like the Firehawks and the Sealights, the Kelvin color is also cool white and 6500K. Objects in front of the Tundra were clearer than with halogens.

The bulbs are designed with an aviation aluminum body and a unique hollow-carved heat sink with a 12,000 RPM turbofan. They draw 70 watts of power per set, which is about average.

Does all of this keep the heat down? Read my test results shortly.

Yet another claim of 50,000 hours of longevity seems like the new normal. Fahren also offers only a 1-year warranty.

Like the Firehawks, these are also IP68 waterproof, so taking the Toyota Tundra out in all weather is no problem.

My Observations

Inside the box, the first thing I saw was a comprehensive user manual with a lot of images. I’m not sure this is necessary, as these are plug-and-play units too.

Fahren’s headlight bulbs mostly have a standard design, but the 9003/H4 LEDs have a futuristic look. There’s a lot of silver; they feel like reliable, sturdy units.

I can’t find any information about the bulb’s chip, and Fahren only states that they’re top automotive-grade.

I like the neat design of the heatsink. Sure, once it’s installed in the Tundra, nobody will see it, but I know it’s there. 

The external driver is compact, like the Sealight, and has a solid feel to it.

The turbofan has a minor issue which could be why these are budget-priced. I’ll reveal all next.

My Tests

I observed an initial rating of 1,417 lux in the projector test. Almost double the halogens, right out of the gate, these are bright!

Just like Firehawks and the Sealight, these bulbs also have excellent heat retention. In fact, they’re 1% better because, after 27 minutes, they drop to only 1,313 lux, or 89%. 

That’s the highest heat retention level I’ve ever tested!

The reflector displayed an initial 2,390 lux. And 2,137 after 27 minutes.

The beam pattern is well-controlled. I observed only minor patchiness in the top and bottom center, the usual weak spots.

I observed 25.9, which is lower than the 35 watts advertised, but that explains the excellent heat retention. 

After 27 minutes, I measured the temperature of the main unit as 185° F. That’s a little high, but the driver was a much cooler 120°F. 

Now for the flaw. The turbofan makes a lot of noise; other drivers have commented on this, so it’s not just me.

It’s a shame as this is an excellent-performing bulb, except for this.

What Other Drivers Are Saying

The Fahren Forscher 9003/H4 bulbs are extremely popular and have over 50,000 ratings and an average of 4.5/5 stars.

Customers love how bright they are and appreciate the additional clarity the Kelvin white provides.

The noisy fan gets a mention quite often, so it’s a significant concern for many.

Summing it Up

For a budget price, the Fahren Forscher 9003/H4 LED bulbs are an excellent choice if the noisy fan isn’t an issue for the Toyota Tundra driver.

Pros
  • Plug and play
  • 12,000 lumens/set
  • 6,500K Cool White
  • +300% brighter than halogens (advertised)
  • Best heat retention I’ve ever seen 89%
  • Best budget 9003/H4 LEDs
  • 50,000-hour lifespan
  • 70W per set
  • External driver
  • Space-age-looking silver design
  • Built-in 12,000 RPM turbofan
  • IP68 Water resistant
  • 1-year warranty
Cons
  • Noisy fan

Toyota Tundra Headlight Bulbs FAQ

Here are the four most commonly asked questions about Toyota Tundra headlight bulbs. 

What size bulbs does the Toyota Tundra use?

The Toyota Tundra has a dual beam fit out, which means one bulb does the work of both high and low beams with the flick of a switch.

The bulb needs to be bright enough to act as a high beam, so the one that works best is the 9003, also known as the H4 or H2. 

What’s the best Toyota Tundra headlight upgrade?

I recommend upgrading from factory halogens to LEDs, as they’re considerably brighter and whiter. 

Standard halogen 9003 bulbs have around 1,000 lumens; LED 9003s begin at 5,000 lumens and go up to more than double that. 

Factory halogens also have a Kelvin color of around 3,000, which is an amber/yellow color. LEDs start around the 6,000K mark, which is white. This color is much more suited for being able to spot objects in front of the truck faster and with more clarity.

Will my Toyota Tundra need a conversion kit if I’m using LED Headlight Bulbs?

The light fittings of a Toyota Tundra are designed for the factory-installed halogens they come with. Upgrading to LEDs may require a conversion kit for some makes and models, as the bulb may not comfortably fit inside the housing.

A conversion kit comes with items like ballasts, a writing adapter, and heat sinks, which can all assist with installation if required. 

Are there any drawbacks to using LED headlight bulbs for my Toyota Tundra?

As LED bulbs are so bright, the beam must be angled correctly. This also applies to the 9003/H4 LED headlight replacement bulbs for a Toyota Tundra.

If these are not angled properly, they could cause glare and temporarily blind oncoming drivers. For safety reasons, always aim the light beams correctly.
