Yeah, it's a REALLY good idea to check behind all of your exterior lights. When I switched over to LED units, I was shocked to see the holes made for the wiring. It honestly looked like they were made with a ball peen hammer, and the marker lights barely covered the holes. I made sure I used a liberal amount of urethane sealant around each hole before the new lights went on, then went inside and filled the holes with spray foam.
