Absolutely, Chloe. I recommend a thin bead of silicone around the base before tightening down, plus a dab in each screw hole. That’s a standard trick RV techs use to prevent water intrusion long-term.

I think you'll really like the # M336FR since it has a tilt feature and it's quite bright, being LED. Are you replacing an existing light or cutting out a new opening for it? The cutout size is 11-5/8" wide x 8-3/4" tall.

Have you already sealed up other exterior lights on your camper?
