AUXITO New upgraded H4 LED High/Low beam LED bulbs are 100W per set, providing up to 600% brighter than OEM halogen 9003 bulbs. 6000K cool white and 20,000LM bring you a clear vision when driving

The 0.03-inch ultra-thin baseboard makes the 9003 Hi/Lo beam bulbs closer to the light-emitting area of the halogen lamp. The latest LED CSP chips spread the light evenly on the road and have zero dark zones, which makes a safer driving.

AUXITO H4 LED bulbs’ size is close to the original halogen bulbs. Almost 1:1 same light filament position effectively simulates stock 9003 LED bulbs’ beam pattern, producing the same light focus. Non-polarity design and the mini size fit 99% of cars and motorcycles.

The all-in-one compact design with full body aluminum material, a 12,000 RPM cooling fan, and 90-degree turning thermal fluid. These three heat dissipation designs make the lifespan of AUXITO 9003 LED bulbs exceed 50,000 hours.
