Improving upon the design of the R7, the R8 amps up the output to 4200LM!
The R8 is one of the most compact bulbs on the market. It features a 1mm thick shaft to virtually eliminate dark spots and increase effective light output. All 4200 lumens will reach the focal point to provide less glare and better performance than other LED bulbs.
For E30 Euro assemblies requiring H1 Bulbs, the small caps with socket may need to be modified. You can follow this write-up from one of our customers http://store.shadowlinemotorsport.com/How-to-get-a-Factory-Look-with-R4-LED-bulbs-and-E36-Foglights_b_2.html.
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.
