I have some moisture in my rear lights in the top bulb, indicator I believe? I removed the light unit to dry it out but it seems to be a sealed unit as there is a shroud around the bulb, any ideas on how to remove this?
had same issue mate if its rearly bad go on shop4parts and just get a new one or take the bulb holder unit off and dry the inside of the tail light out with a hair dryer.
you will find either the top of the tail light will let condensation in or the bulb uunit. Could try using a bead of high temp silicone.
