Max, it is a direct replacement for the bulb, uses OEM reflectors, heat is managed by a small fan on the base of the bulb. These will be tested on hard core dirt bikes, if they hold up to the dust, vibrations, and moisture under these conditions I feel %100 confident they will perform well on the street. I am a light whore, the GS is lit like the 4th of July once I am off road. This version is new and will not be for sale until several bikes have run them with satisfaction and issue free. I'll be running them when I do the AZ and UT Back Country Discovery Routes, some brutal miles on a fully kitted GS. Not a place to run out of lights for sure. If they fail? I'll report as I sure as heck do not want to endorse something that failed.
