1156 LED Lights in Cuddy. Issue.

[BajabossJD]

Hey Guys,

Just got in some nice 12 LED 1156 Lights for the fixtures in my Cuddy. Currently, there is a 1156 ST in the fixure and it works fine. I put in the LED 1156 and nothing. I went back to the old one and it worked fine. I then was playing around with it and touched the outside of the socket to the bottom of the LED and it lit very dim.

What do you think is the problem here?

You might check the polarity of your socket. Usually it's - on the shell, + on the inner contacts. It won't matter for standard bulbs.
Also, that bulb doesn't seem to send light back into the reflector. Almost all of it is directly radiated. The light's output pattern is based on the design relationship between the point source of the light, the reflector geometry, and any lens details. You'll have to decide if any of that matters in your application.

Almost certainly the polarity is the issue. LEDs are one direction current flow only. Old fashioned Incandescent bulbs do not care which direction the current flows.

You guys were spot on! Switch the wires, good to go.

Thanks!
