I ordered reverse lights 921 for my 2006 Gt And there awesome its just that i have to put in reverse then take it out and then put it back in reverse for them to turn on and sometimes that does not even work they flicker and shut off does anyone know why or where i can grab some gooooooooddddddd ones PLEASE!!!!!PM ME

 

Could be a couple problems:
1) check for corrosion in the socket, or bulb not inserted correctly.
2) Might be the reverse switch at the shifter sticking.

If you have a volt meter and a helper - try taking a voltage reading at the bulb socket while someone operates the shifter and see if proper voltage is getting to the socket.

If yes - check bulb connection
If no - check reverse switch at the shifter.

Hope that gets you going.

 

you know man the bulbs are fine its just weird like the ford computer is like rejecting the bulb it turns on then off and then it wont go back on

 

If you put a standard bulb and a led bulb in the other side do they both light up?
