I am looking to upgrade my fog lights to LED. Dont really feel like going as far as the $150+ kit from TRS that i have seen a while ago but rather just a simple LED bulb swap into the current housing. I am looking at my options and am unsure about if the fog lights need a cooling source. I have read is that fog lights draw less power so (maybe?) you dont need cooling?? Id love to know what other peoples thoughts are about this because i am fine with going either way i just dont want to buy ones without a fan and light my car up in flames from an electrical fire. Thanks for any help!

They draw less power but still get hot, about 180°F. Most decent LED bulbs will have a heat sink to draw the heat away and dissipate it. Some have built in fans but I'd stay away from those.
