@vmaxflame. COP RUNNER showed us this mod some two-three years ago. when you read through the two threads you'll notice the evolution of which bulbs to use--from the traditional, wire-filament with colored-glass to LEDs with high mcd ratings. [if anyone wants, i have a set of four blue wire-filament that texmax gave me when i first tried out the mod. PM me with a mailing address if you want them. FCFS]
i remember trying to figure out which color to go with, and how tedious it was clicking through the two threads hunting for the pix. so i collected a representation of them all into one post. sorry, but am too lazy to figure out which pix are of wire-filament and which are of LEDs--didn't think it mattered anyway, just the color change is worthwhile. happy modding.
