installed a Whelen TIR3 today... Holy Crap is this thing bright . Easy install replacing the lower reflector. Thinking maybe of hooking it up to my EC Super flash that I have on my spoiler light and just making the spoiler light function as running/brake/turn signal. Would be nice if EC made the spoiler light as bright as the Whelen. Want to make the Whelen flash a pattern then stay on constant. These thing could be addicting...:thumbup: It may pi$$ somebody off being behind me (especially at night), but they have to see me now!
