Rear Fog Light Heat

Fountainhead · 08-16-2013, 04:46 PM

I put LED bulb from VLED and replaced the incandescent, wires were not hot, don't know if bulb was hot but I replaced because wire harness was not designed for additional 25W load on brake light. No one has ever had a problem but I feel better now. Not as bright but sufficient.

Well after taking out the bulb I can see why the fog light got so hot. Look at the size of the bulb! its also 12V 21W #7440. LED is probably the way to go, not sure if I'll have trouble with the reduced watts like other situations LED sometimes create, but its worth a shot, I really like the looks of the light at night. Thanks again for your suggestions.

Just buy a 7443 bulb, cut the outside leads off and move the inner leads over to that position. Someone else on the forum did a DIY on this (did a quick search and did not find it to reference) and it solved my issue of the bulb being too bright and too hot when used full time. Took all of 2 seconds though and if you had a 7443 bulb it would be apparent.

I had simply wired it to my license plate light so it was on whenever the lights were on.
