I recently discovered that the fogs from my tail lights were coming from the temperature difference on the inside of the tail light and the outside air( When the fog was present I poured warm water on the lens and the fog disappeared), therefore creating fog on the lens. Whenever the lights are off the fog disappears. i was just wondering if there was anything I could do inorder to get the warm air in the housing circulated so it would stop the fog from occuring. Also, Is Led stop lights a good idea...1) they produce less heat, 2)use less energy and most likely would result in less fog occuring. The current chrome bulbs get really warm. THANKS in advance.
