Please don't flame, I know its a bit tacky but I got an idea on my way home from a friends house. AutoZone sells the truck bed LED bars as a 3 piece set to fit any size bed. I prefer the AutoZone brand mainly because its clear when not in use not red like everyone else's. Well anyway what if you only use the center piece and mount it in the lip of the 4th gen rear bumper. Then all you do is splice it into your brake and turn signals and you have a functional LED signals.

 

Brake lights at the bottom of the bumper? Bad idea...

 

Unfortunately my 92 Si didn't... speaking of that does anyone know how much the LED spoiler runs? OEM or OEM replica?

 

130$ for one that needs refinishing (you could paint them no problem) and probably 270$ brand new!

You could get cheaper at a wrecker maybe!
