Does anyone know how to make LED fog lights work with the OEM setup? I bought some LED fog lights and tried to install them but they don't work properly and just blinks when hooked up.

 

Are they DLR's or just the 9006 plugs with a bunch of small LED's..? You will need to add resistors inline to the positive and negative wires to make it work.

 

Easy, Ive done it to previous cars. Im doing it to my SL63 right now. Buy a HID conversion kit. I buy mine at hidextra.com for about $50 to $80 depending on the better quality. I got the $69. You get wiring, 2 ballast, and 2 bulbs. The fog light is H7. So you get a H7 kit. and pick the color. I got 6000k. distinct blue tint. I am trading to 5000k, a little whiter.
Replace the bulbs with the new. Plug in the wiring or splice it if your connectors dont match.
