A few of the lights went out on my Delco radio in my ‘98 Silverado, so after seeing this page I decided to give it a shot. While I was at it, I put red LEDs behind my gauges.

The other guy’s method was to glue the LEDs in to the faceplate. I tried this at first, but soon realized that it makes much more sense to just solder the LEDs onto the board, cut a few traces, etc. It worked great. The radio looks really cool. I’m still debating the gauges, though. I think having orange needles with red gauges is the problem. Stay tuned.

As an added bonus, since the LEDs in the dash and the radio draw only a fraction of power that the hot 12V bulbs did, the headlight switch stays a lot cooler. The only drawback of all this is the inability to dim the lights (but I don’t see that as a drawback anyways). I highly recommend this to anyone looking for something different.
