So I changed out my OEM fog light bulbs with cree (something i've done before). I left one side OEM to compare with the cree bulb, both bulbs lit up fine. After installing the second cree bult, neither side lit up. Did I blow a fuse or something?
Thanks in advanced for tips/advice.

 

You have to be careful with LEDs. Too much juice to them will burn them.
I have aftermarket wiring for my fog lights and I've done Cree Leds already using a
20amp fuse. Always use a strong fuse.
Also, check the connection and make sure the bulbs are plugged in tight.

Where did you buy the bulbs from?

 

I bought from an ebay dealer a while ago, forget the seller. I do know the bulbs worked because I installed them to make sure. They've been sitting in my garage. I'll check the fuse tomorrow.
