I replaced my F350's fog lights with these Auxito H10 LED bulbs. The passenger side had pretty easy access to twist and remove the old light with the pigtail attached. The drivers side you can do too but, you'll need to slightly pull on the top of the License plate holder (right side or pax side) enough to allow your left hand, wrist and arm to snake its way over to the back of the drivers side fog light. That is the only way to get there unless you start taking stuff apart. Next, slowly twist out the old light, put in in the new LED and you're off. The improvement is fantastic. I cleaned up my lenses as they were hazy. Color is a bright white, output is great and not scattered like other LEDs in halogen housings.
