Like other reviews have said, I also found the side marker lights very easy to install. The only problem? They're brighter than every other light on my 1983 Coleman Columbia camper. I'm thinking about replacing the rest with e-trailer lights! And the service was first-rate... Not always the case with e-commerce outfits.15767
