@ RUSSIAN Be sure to turn the lights and turn signals ON while you test. if the lights are off they will test as ground, all sockets only have 2 grounds.

What is a ck bulb

[vledscom]

@krishneel1133 "CK" is the term used to identify a 3157 or 7443 automotive light socket that has the GROUND connections in different positions from a standard 3157 or 7443 socket. Filament bulbs work in either socket without any problems, but LEDs are polarity sensitive. For this reason we have a "CK" and "Standard" versions of our 3157 and 7443 LEDs to work for both socket types.

what about a 3057 socket? im getting one ground out of the four contacts. is this normal? and will ck type LED's work in them?

IM GETTING THE SAME RESULTS AS RUSSIAN!!! I have a 2005 f150 built in late 2004.

I have the lights on and even blinkers and my bottom two that are on opposite sides will blink and the top right is a steady on, then top left is not reacting

So, I tested mine and I had three grounds (three of the contacts made the tester light up). What kind of socket would that be? I'm guessing standard, but not really sure. It's a 2004 F150.
