One of my fog lamps just died on my 2010 JK and my local jeep dealer wanted $46 for single replacement bulb. Apparently the 2010+ fog lamps differ from the 2007-09 and Slyvania doesnt make a replacement yet. I bought a 2504 LED equivaliant which looks good to an observer but when behind the wheel its next to useless compared to the OE lamp, its only about half as bright.
The only other aftermarket fog Lamp I've found is made by Putco Premium Lighting and its gotten horrible reviews with people stating that it runs way hotter than listed and has melted portions of the light housings.
Does anybody know of a good aftermarket 2504 bulb? Has anybody tried a GM ACDelco 15839897? It seems to have comparable specs. and the same form factor.
