My headlamps are cloudy to the point that it's hard to tell if the lights are even on. My truck lived for a time in Colorado, and I don't know if they do stuff to melt snow that kills plastic or not, but my lenses are toast.
I'm shopping eBay and finding that there are loads of selections that cross several models and years. Some exclude a couple of years of the SVT and Harley trucks, but include the same years of the regular trucks, like mine. The Harley and SVT headlamps should fit my truck, but they look like there is an impact on the turn signal assemblies.
I found several options for under $80, and some are over $200. All are aftermarket, and most claim to be DOT and SAE certified, and this is an obvious requirement.
I might be interested in a different style of headlamp, but obviously can't use one that has a different mounting mechanism. What limitations are there? Do all of the lamp assemblies for all of the models the same from the perspective of the mounting method? (This seems to be the most significant factor to me.)
