Yesterday a few of us were together and were talking about the LED replacements that I put on my car. I used a 1" by 4" LED strip designed as a brake and turn signal set and mounted it in the Lucas rectangular lamp at the rear of the Cobra. Here is the link to the guy that sold me the LED. He really knows his stuff and is very helpful. They work great. They are extremely bright and very visible even in direct sun. Contact me if anyone has any questions. I modified a set for Blackjack and he is very pleased.

If anyone needs help on how to modify the bracket to mount them just ask me.
