So I added another parking light to the tails. Basically did the same on the Tahoe when it had halogen reflector style tails. Same parts needed as the front with extra signals, just another pair of 3157 sockets and gold resistors to stop hyper flash since I put in another set of jdmastar red led bulbs including the jdmastar bulbs on the top spot too for parking/brake light. So when the parking lights are on the top and bottom light up, then the functions for the top as brake and the functions for the spot below for signal all still work the same. The leds make a huge difference bright with a deeper red color to them.
so if I ever have a taillight out I’ll have 3 more left lol
