Sealight H4 LED Bulbs X1 Series Dual Xenon

Overall Best

Sealight’s H4 LEDs are a huge upgrade over stock bulbs, offering more powerful lighting, enhanced visibility, and best in class lifespan.

These bulbs use LED chips that enable a three times brighter light output than stock. Pairing a wider angle of projection with longer throw, you get noticeably better road coverage and improved visibility, both downroad and to the sides of the road. 

For drivers who require better clarity from their headlight setup, Sealight’s H4 LEDs produce  a solid and uniform beam that does not flicker and eliminates the appearance of dark spots in your line of sight. 

A 6000k color temperature makes for a pure white beam that is a great deal better than stock for identifying road signs, cyclists, other cars and animals in your path. 

Cooling is another important factor for a high performing set of LEDs. Sealight have implemented a unique cooling method that is fanless and completely silent. It employs a larger surface area for heat dissipation, keeping temperatures low and performance up. 

Startup on these LEDs is instantaneous, with full brightness achieved quicker than you can blink. They claim 20 years of usage with 6 hours of driving every night. Consumer feedback suggests the same, with glowing reviews for durability across the board.  

Pros
  • Dramatically brighter light
  • Pure white beam
  • Longer throw
  • Wider field of view
  • Improved visibility
  • Easier to identify hurdles
  • Efficient cooling
  • Uniform beam pattern
  • Instant startup
  • Improved longevity

Mumasha H4 LED Headlight Bulbs

Best Budget

Considering its price, Mumasha’s kit delivers the best value of any H4 LED we’ve tested. It is bright, has a cool white color, and long lifespan, especially for such a budget friendly option. 

Coming in at 7600 lumens, these LEDs are definitely brighter than most stock alternatives. Our tests showed improvement in visibility, with a longer throw and wider road coverage to match. The quick startup is a nice touch that makes this kit feel more premium than its price tag suggests. 

The Mumasha’s also have a uniform beam pattern and impressive focusing. These two features make your sightlines clear and free from dark spots that plague cheaper LED kits. Another feature that we really liked is this kit’s cooler tone. 

The pure white, 6500k beam these LEDs generate is ideal for lighting up the road and helping the driver distinguish between various obstacles, road imperfections, and cars. Furthermore, the Mumasha’s do not flicker or flash unnecessarily at any point during their operation, making them a stylish addition to your car’s front end.

A high quality aluminum housing makes these LEDs well built and durable. Longevity is aided by the inclusion of an IP68 water and dust resistance rating.

Furthermore, the aluminum casing allows for significantly better heat diffusion and lower running temperatures, making the claimed 50,000 hour lifespan of these LEDs a bit more realistic.

Pros
  • Improve peripheral visibility
  • Easy install
  • Pure white color is very reflective
  • Adds style 
  • Long lasting 
  • Uniform beam pattern
  • Eliminates dark spots
  • Less power consumption

Fahren H4 Cool White LED Headlight Bulbs

Premium Choice

Fahren’s H4 bulb offers substantially higher brightness, alongside a solid and focused beam of light. The color tone is cooler and the kit is less power hungry than your stock bulbs, enabling better longevity and performance. 

This Fahren kit is one of the most powerful kits we have ever come across. We found them to be over six times brighter than stock, while also having a longer throw that makes for better downroad visibility. The advertised 20,000 lumen brightness has our seal of approval for being one of the best for nighttime driving.

The beam pattern of these LEDs is solid and does not have any dark spots. It is clear and well focused,improving the driving experience on wider highways and country roads with less illumination. 

The 6500k color temperature is pure white and reflects off of surfaces better, making everything from cyclists to potholes more easily visible. Having driven in less well illuminated settings, we can report that other vehicles and obstacles were easily spotted and avoided

Efficiency and longevity also benefit from this setup. The Fahren’s design features a unique hollow heat sink that diffuses heat better, while a high speed cooling fan that can go up to 12,000 rpm keeps temperatures low. 

This combination keeps the whole setup running smoothly, thus prolonging the lifespan of your headlights.

Pros
  • 6x brighter than stock
  • Pure white color
  • Uniform beam pattern
