Leppein 9004 LED Headlight Bulbs – S Series

Overall Best

Leppein’s LED offering delivers the most balanced package of any 9004 headlight bulb. These bulbs improve visibility, add clarity to your sightlines, and outlast even the most efficient stock bulbs.

Leppein uses a 24 CREE chip architecture to generate a 6000 lumen light output. That is more than enough for daily driving, and makes for a massive improvement over stock bulbs. Also featured on these bulbs is a substantially longer throw that stretches farther down your path, and a wider angle of projection that brings more of the car’s surroundings into view. This combo is perfect for illuminating wider highways and country roads.

An ultra white 6500k color temperature is ideal for visibility and adds a tonne of style to your car’s front end. The beam pattern is expertly calibrated and lacks any unsightly dark spots. Moreover, the crisp, piercing beam of the Leppeins helps pick out objects, hurdles, and hazards in the distance. We speak from personal experience when we say that these headlights significantly reduce driver reaction times.

Flickering or flashing can ruin the look and effectiveness of a bulb. Thankfully, these LEDs eliminate both with a constant beam that is solid and focused. It does not appear blurry or hazy, even after heavy use.

To cool these powerful LEDs, the manufacturer has incorporated a TurboCool fan and all aluminum body for optimal heat diffusion. The advantage of this setup is low running temperatures, which when paired with the more efficient power consumption, result in a lifespan of over 30,000 hours.

Pros
  • 6000 lumens brightness
  • 6500k color temperature
  • 30,000 hour lifespan
  • More intense light output
  • Whiter color
  • Farther throw
  • Wider projection
  • Better visibility
  • Uniform beam pattern
  • No dark spots
  • Flicker free operation
  • Lower power consumption
  • TurboCool fan improves airflow
  • Efficient heat diffusion
  • Long lifespan
Cons
  • Even brighter options available

S2 Series 9004 LED Headlight Bulbs

Best Budget

The S2 Series 9004 LEDs provide a more affordable alternative to stock headlights, without sacrificing performance, durability, or lifespan.

At 6000 lumens, this is a powerful bulb that is vibrant enough to hang with the more premium options. The S2 generates a crisp, focused beam that improves visibility. It also takes a leaf out of Leppein’s book and features a wider field of view and farther reaching throw, helping the setup encompass more of the road.

Color temperature also sees an upgrade to 6500k, resulting in an ultra white beam that is as functional as it is aesthetic. Even distribution of this whiter light also adds uniformity and precision. As an added benefit, it helps combat dark spots. Overall, the color profile of these bulbs is fantastic, and really useful for identifying safety hazards and uneven road features.

Build quality is similarly top notch, featuring an aluminum shell around the COB chips. The high velocity cooling fan can reach speeds of up to 12,000RPM which significantly improves airflow and heat dissipation. The durability is bolstered by an IP68 rating that shields this kit from the elements.

By drawing less power, the sensitive internal components of this LED kit are safeguarded for extended use. That said, some drivers report having radio/stereo interference with these LEDs installed, though that can be rectified with an additional decoder.

Pros
  • 6000 lumens
  • 6500k color temperature
  • COB chips
  • IP68 weatherproof
  • More intense light output
  • Whiter color
