I am replacing the bulb in the glove box of my '65 fastback with an LED. The incandescent works well, but I like the looks of the LED. When I tested the LED bulbs they work, but in the glove box they don't. What am I missing? I plug the incandescent back and it works. I test the LED and they work. Just not in the glove box socket.
Thanks

Have you checked the operation of the LED with clip leads?  Maybe the bulb does not fit the socket well?

Switch wires to the  led bulb, they are polerized, so = to incorrect side and it wont work

I was in a hurry when I posted my first reply.  Hope this makes more sense. To get the LED to work you will have to isolate the glove box switch. Like Steve said, the glove box switch allows current to flow from dash wire through bulb to grounded switch body. The contacts on the LED are polarized. It appears that you need to use an LED socket or isolate the Ford socket/switch and apply power to body of switch and ground the wire that is now used as power for the incandescent bulb. This would reverse the route of the power through the LED bulb.

Hey MWM,
I got this peach pink leisure suit with a flowery shirt that would look Great in the lack of light that LED will give in the glove box if you are interested. OBTW bell bottoms too!
