I can't get my rear fiber optics to work. It's hard to believe that they are torn since they are in the same harness as the rear lighting. Is there something I can do to the ends to prove light continuity. Is there a test to make sure they are still connected. Thanks for the help.

Do you have the center console apart where the fiber cables plug into the bezel? If so, remove a tail light lense and the bulb. Have someone shine a flashlight on the calbe end that is sticking into the tail light. Now look into the end of the cable at the console. It will help if it's dark. If the cable is not broken, you should see the light. Just think of the fiber optics as a tube, you shine light in one end and it comes out the other.

The plastic unit the fiber optics connect to in the console in front of the emergency brake can be broken easily and not retaining the fiber optics correctly. A new one is available from most of the Corvette parts venders. It is neat to be able to see your lights work with the fiber optics, plus could save you from getting pulled over for no tail light.

Has the vette been painted? The ends in the light housing my have been painted over.

Mine (a '69) were painted and broken. I tried to repair them, but found out the fibers had either aged or been damaged and just didn't transmit the light anymore. I replaced all three. I disassembled the cable after removing it and put the new fibers in using the old ends. The new ends provided were not correct.

Unless it has been severely damaged or broken, the light cable is almost NEVER the problem with these things. In fact, a damaged/broken cable can be spliced. The most likely problems have been mentioned already:
1) damaged cable "receiver" in the console such that the light cables aren't properly retained;
2) ends of cables in taillight housings being painted over, dirty, etc. so that they cannot receive light from the bulb;
3) your taillight bulbs don't work [probably not the fault].

Thanks guys. I will start by removing the ends and shinning a light at the end and see if it transmits. If not I guess replacement is the only way.

Thanks again

Consider replacing the fiber optics with LED "spots"
I may do this if I am not happy with the fibre results.

The exception to this if if the cables are disrupted and fall into the mufflers and are melted. I've seen this at least twice since '76 when I got my '69. Thankfully the problem was on other cars, not mine!

UH excuse me, what would the logic be in replacing a system that is MONITORING the actual lamp performance with another lamp system. Your "Idea" wouldn't tell you if the actual lamp was working or not, I guess you don't undestand the logic of the fibre optic system.

I understand the logic of the system.....I just like to look at pretty lights!!!!
