Fog lights no longer turning on

Hey guys, just wondering if I can get some help or advice.

So I just noticed last night that my fog lights were no longer turning on. I believe I had them on when I shut off my engine last night to go watch a concert but not entirely sure and I noticed that they were no longer working while I was driving after. They usually turn off when I lock my truck and the only mod that I've done to them was to replace the oem bulb to opt 7 led fogs. I doubt its the bulb since I've only been running them for less than 2 months. Any advice on what could be the problem and how to go about on assessing and fixing it? Thanks in advance!

 

you probably blew a fuse, if that's not it switch back to the Halogens see if they work with them in it

 

Pull a bulb and check the socket for power with a DMM

 

Don't put LEDs in your halogen fog assemblies, it causes excessive glare. See this thread as to why:

But as mentioned the first place to start would be the fuse. You have a spare in your fuse box you can swap it with under the hood. Cheap Chinese LEDs fail all the time, so it is not out of the question they both died. Putting the OEM bulb back in would be a good test to determine if it is the circuit or your LEDs.

 

Ran the same brand of led bulbs in mine, they shorted out and blew the fuse. After only a few months.

 

The seals on those bulbs are crap also, I kept getting moisture in mine. Swapped back to quality halogens and no more moisture.

 

So I checked the fuse box and the 15a fuse was blown. I had spare fuses but they all blew as soon as I replace them and turned the fogs on. At least I know the LEDs still work and the blown fuse is the only problem. I might end up switching to a halogen bulb but a buddy of mine mentioned to maybe try a 20 or 25a fuse. Do you guys think that’ll work?

 

Absolutely not, that is a horrible suggestion. The fuse at a specific rating exist to protect your circuit from exceeding the rating of the circuit. Your LEDs should consume much less power than the halogens. Clearly one has failed badly and is shorting out, which is the only reason why they would exceed the OEM rating. Increasing the fuse rating to overcome a short is how vehicles catch fire, which is what the fuse exists to prevent.

 

Thanks for the heads up
