I am assuming that you are referring to the headlights or do you mean all of the other lights? I replaced all of the lights on my 2015 with LED except for the headlights. The difference is massive, they are brighter in every way possible and the light is white, not yellowish additional perks are they last longer, run cooler, and do not use as much electricity. I had a 2010 F-150 that had terrible headlights, and I see my 2015 uses the exact same lights which are equally as bad.What are the advantages of LED's over the other lights? Am I going to say i can't believe i didn't have these before, or is it not that big of a difference.
