Genuine Phillips ZES chips allow these bulbs to provide more light and run cooler than our previous bulbs. When combined with a small 1.25mm luminous point on the shaft the results are impressive.
The small luminous point means less stray light and glare, which equals more effective light on the road where it needs to be.
By eliminating the braided copper and replacing it with a heatsink, the overall size is within 2 cm of the standard halogen bulb of equal type.
For E30 Euro assemblies requiring H1 Bulbs, the small caps are not compatible.
RECOMMENDED FOR HEADLIGHT SYSTEMS DESIGNED FOR HIGH INTENSITY LIGHT SOURCES, SUCH AS HID AND PROJECTORS WITH PROPER CUTOFF SHIELDS. CHECK YOUR LOCAL LAWS REGARDING LED BULBS FOR USE ON PUBLIC ROADS BEFORE PURCHASING.
