How to install this light?
Harold R on Nov 20, 2016
BEST ANSWER: On a scale of 1-10, its a 9 being hard to do. You have to pull the bumper away from the headlight. To do that you have to pull out about half the fender liner around the tire, remove the shroud above the radiator, loosen the bumper bolts on that side. Top two bolts holding the light are on top and can be seen. The outer lower is accessed thru the wheelwell, or from below if its up on a rack. the inner lower is just a plastic push-pin that snaps out/in a plastic holder. Put tape on the bumper all around the light so you don't scrape the paint when pulling the light out. If all that sounds difficult, in practice its worse. Or, pay a shop to do it.
