2015 AF 990, Do I need to re-caulk the running lights?

I had a slow leaking running light on my pop-up camper and the strip of OSB board behind the light got wet sufficient enough times to become punky. My solution was to slowly soak the OSB with craze glue until it became saturated but not drip and let it harden to become strong again. Then I used Proflex all around them to make sure they did not leak again.

Look at my thread on rebuilding my 811 nose because of the running lights leaking. The pressure on the front of your camper at 60 mph is tremendous. In a rain, it will push the water in any availiable opening. I am removing the 2 center lights, because I will be replacing the Filon, and changing all running lights with led. Caulk and check every 6 months, park in a shelter if possible.

Water does flow uphill. The OP was talking about running lights on the nose cap of a TC. I would seal the entire light. I also use pro-flex.

Leave the bottom open so any moisture that finds its way into the light has a chance to drain out. Water doesn't flow uphill very well...

The wire holes are opened holes. I would run a bead of caulk around the entire light. You should have LEDs on that unit since its new, so they are sealed lights, but I would want caulk around the whole light. I used Proflex when I installed my LED marker lights. My AF is a 2010 and back then they still used the old style lights that were notorious for leaking.
