The factory halogen fog lamps were very dingy and didn’t provide much additional light. I swapped out to AUXITO LED fog light bulbs and that's a big improvment. Now I’ve got a brilliant amber additional light source. The placement on the outer corners of the bumper really helps light up the shoulder on dark roads. They were a bit of a pain to change on my particular truck, but that’s an F350 issue and no fault of the bulbs. In fact, they are a perfect fit and the factory wiring pigtails plug in with a nice solid, positive click. I haven’t had a chance to try them out yet on a really foggy day, so that remains to be seen.
