It's a strip of LEDs. You can't replace them unless you cut the housing open. Most here simply get a replacement known good tail light from another member or a junkyard.

I guess they were assuming the LEDs in the assemblies would outlive the cars, and in many cases they have.

The Tbirds around this time were costing Ford about $800-$900 more per car to make than the CEO wanted. If they would have made it so it could be replaced that would have added to a car they were trying to trim down.

Back then working with LED's (for the average person) wasn't common and very expensive. LED manufacturers also still claim that LED's last forever and some do, some don't. But yes, many of these have outlived their original car.

If you're confident enough that you can get it apart then glue it back together and make it hold then the LED strip is simple to replace and people have done it.

IIRC the circuit board is what usually gets toasted on these, not necessarily the individual LEDs themselves

Yes either the board and/or the resistors. I thought there was an article on this and there is but it's not complete and the old posts I found were from 2002-2003. LED's have come a long way since then so I think it would be fairly easy to find something to replace the circuit board with as long as the voltage matched.

I think the hard part is getting the thing out of the housing and then being able to get it back together. I just bought a new complete set with no black strip and may mess with the one I know isn't working right.

Added: I found a strip that will fit, just need to check the current draw on the OEM light. I also noticed that when Rolling Thunder cut the back to get access to the strip he just cut a small part and it damaged the silver/reflective paint. I was thinking to cut it on the side, just like 1/2"-1" an inch from the lens all the way around. it's a way bigger cut to make but may be easier to put back together.

If I can get it to work I'm going to check into the cascading flasher and tie it into the blinker.

RELLIK, Keep an eye on Ebay but don't pay too much. I just got a full set (no black strip) for $100, for all 4 tail lights. I saw some corner lights too that were NOS still in the box going for $26 each (no black). I've seen the trunk lid lights go for $100 each so have patience. Always ask the seller if the LED's work. That way if they don't work when you get them it's documented they said they worked and you can return them.
