I have a 200 F-150 and got those snazzy "ero" lenses for the front turn signals so that the lights are all white (when the turn signal isn't on) it looks great with a dark truck.

one problem though, there is moisture in the lenses so that they get fog on the inside, this looks a little less cool than I would want it to look, and I think it is making the yellow on the turn signal bulbs flake off (at least I think it is the moisture messing up the bulbs, it may be somehting else).

Is there any way to get that moisture out and keep it out?

is it as easy as taking the lenses off and wiping them dry on a day that isn't too humid, or is there some seal or something that has not been set correctly?

 

One of the problems with some aftermarket lenses is moisture leakage - and fogging. You need to do two things to rectify the situation. First, you need to determine where the moisture is getting in - and re-seal it. It's generally where the lens is sealed to the housing or where the bulb slips in.

Second, you need to dry out the lens / housing assembly. The only way I've found is to remove it, turn it so the bulb opening is up (with the bulb out) and use a blow drier to gently heat the whole shebang. Make sure you've really got it all dry, them re-assemble the whole thing and see if you got to the root cause. Good luck.
