it took a bit of modding, but i used the red 3157 LED bulbs just like i have in my brake lights, after a lot of sweat(working in the garage w/no AC, than walking out to my car in the driveway to wire this shit up in 100*f weather...sun blazin, i got it done

all installed, wire loomed, and working...the bulb itself it pretty long u wont be able to twist the 3157 connector on, but you can do it another way, how i will leave a secret...but ill post some vidz once it gets dark, too much sun light right now, plus i have to get ready for a meet a few locals andout of towners have planned

So you honed out the base and wired in new sockets?And you calling that the"right way" is really inaccurate.There are many "right ways".Watch out for melting the lenses as well since 3157 bulbs are alot brighter thus bring alot more heat.This is the exact reason why I used the 194/921 combo
both lights are made out of the same plastic

if my other ones can take the light from the LED, than so can the reverse lights
