These new high-output LED Headlight bulbs create a 4,000+ Lm blanket of light for the driver to increase safety and nighttime visibility. Philips Luxeon ZES chips allow for the increased Lumen output while still drawing less than half the power of the factory headlight bulb. These smaller chips also have excellent heat dissipation characteristics, making them extremely reliable even in harsh environments. The new internal driver components were designed by Samsung and offer excellent performance in a smaller package. The new adjustable heat sink makes fitment issues a thing of the past since it is removable to reverse install or mount outside the headlight back-cap for added adaptability. More illumination, increased reliability, and easier installation… all for LESS than before!
