I just installed his tail light sequencer for the rear tails on my 87Tbird.It went nice and smooth. It took me 3 hours to do it but I took my time.I was able to not use the aftermarket light sockets but spend the time with a file and make a stock Ford tail light socket work.It was alot more work then putting in the aftermarket piece, but it looks stock. If your thinking of doing this... it is nice and easy upgrade with no problems at all.
Glad to hear you're happy :D
