My wife and I have a 1951 Ford F1 and I was looking to add LED taillights to my 6v, positive ground system. I had checked with a number of places up and down the East Coast and at some big car shows, but the Model A Garage seemed like my best bet.... and they were!!! The project turned out to be more involved than originally thought, but John stuck to the original quote and turned out a terrific product that reflects high quality and value. And now I no longer have to worry about someone telling me my brake lights are out, because these babies really light up!!! A big shout-out to Jennifer, who works for John at Model A Garage and who was very helpful throughout the entire process. I would recommend these folks in a heartbeat!!!
