I like this. Got new LED taillights and finally adding marker lights for the fenders (I feel blind without them at night). I've had to load a couple times at night and it can be difficult to see, though the taillights do help a lot. Probably overkill, but would probably be helpful.
My concern would be how durable the tape attaching method is considering boat trailer get wet, dry, hot, cold, and can ride pretty rough down the road. Any way to screw or bolt these on? Or will the tape really last 10+ years? Could be a real pain replacing it.
