So I recently picked up a set of 18w cree LED offroad lights for my jeep. Mounted them to my new bumper up front and figured I'd wire them up to the factory wiring since the jeep previously had factory fog lights. The new LEDs won't turn on with the factory wiring tho. Am I missing something? I figured the wires and output of the factory lights would be more than enough for the low output LEDs. Thanks for any help in advance.

Check the fuses ? Also factory lights only came on of the parking lights and lowbeams were on

Check the fuses all good, and I turned all the lights then hooked the new LEDs up. Still nothing.

Switch the polarity of the wires.

Did you test the LED unit before hooking it up? Does it come with a "control box"? I know my 10" LED light bar did. I axed my factory fog setup since I did the Putco harness upgrade, and I spliced the positive end towards the switch in with the positive on the cigarette lighter, so that it can only come on with accessory. Works great.

Already checked polarity. And I did check the lights before install. I touched the leads to the battery terminals. All worked great. Just can't figure out why they aren't getting power thru the factory wiring.

I was going to suggest the same thing. LED's have to have the positive on the positive, and most of the time when they don't work, you just switch the leads. I can only think of three things. 1. Polarity is wrong 2. You've not spliced into a 12v line properly, so you're not getting power 3. you are't making a good ground
