Well I am finally getting to this mod that I wanted to do last year. I have LED bulbs in place now but wanted something different. Found a company that will change your Supra lights to LED rings which looks killer, just out of my price range, around $700, use your lights!! I used my old set to try all that is needed, & made up some LED panel inserts. So today I started this mod, first remove the tail lights, separate the outer lens, remove the inner lens, get a fitment, & plan it out. Looks like a tennis ball cut in half will center the LED plate, glue together ,glue in place. The wires I'll run through the stock bulb socket, which has rubber wire seals & a rubber sealing ring.
