Re: Moisture in Headlight Lense
All composite headlight housings have a drain hose. Condensation is rather common if the rubber O ring on the bulb itself is mispositioned or the drain hose is kinked or plugged up with debris. Assuming the bulb O ring is OK and the drain hose is as well, clear silicone can be applied around the lens where it joins the back. Use the cap with the second sized opening cut off its tip.
