1 year old Thor Ace 27.1 with water intrusion in the tail lights. I removed the tail lights only to find rusty screws and wet wood due to sitting water. I called Command Electronics, the maker of the tail light assembly and they promptly sent me replacement gasgets. They suggested I caulk the assembly after swapping out the gasgets. After thinking that these lights were already leaking after only 1 year, I decided not to use any gasget. Instead, I allowed the wood to dry and coated the wood with fiberglass resin. Once dry, I placed the light bulb housing back into place leaving a 1/8 inch space between it and the RV. I put a bead of GE silicon caulking around the bulb housing (except for 6 inches on the bottom, just in case of future leak) then tightened it with replacement stainless steel screws. I finger finished the caulking and allowed it to dry overnight. The following day, i removed the screws and reinstalled the lens covers and added o-rings to each stainless screw and tightened them up. I then silicon caulked the lens cover and completed the project. It has a much cleaner look without the foam gasget being seen as it previously was. It is now 100% leak proof, as it should of been from the factory. Here are some pics and hope this helps anyone with a similar issue.
