Summary: SOME CUSTOMERS MAY COMPLAIN OF CONDENSATION/FOG INSIDE THE FRONT (HEADLAMP/HEADLIGHT) OR REAR (TAILLAMP/TAIL-LIGHT) COMBINATION LIGHTS. THE RECENT NEW MODELS HAVE BEEN FITTED WITH A CLEAR LENS WHICH CAN CAUSE THE SYMP-TOM TO BE MORE NOTICEABLE, HOWEVER, IT DOES NOT AFFECT THE PERFORMANCE OF THE LIGHT. THIS CONDENSATION/FOG IS A NATURAL PHENOMENON THAT OCCURS WHEN THERE IS A FAIRLY LARGE TEMPERATURE DIFFERENCE BETWEEN THE INSIDE AND THE OUTSIDE OF THE LIGHT HOUSING. IT IS NORMAL FOR VERY SMALL WATER DROPS TO APPEAR IN CERTAIN LOCATIONS ON THE LIGHT UNITS WHERE THE AIR IS STAGNANT (CONDENSATION), MAKING THE LENS LOOK WHITISH (FOG). THIS HAPPENS MOSTLY IN THE CORNERS AND NARROW SPACES, AND WILL TYPICALLY CLEAR DURING WARMER AMBIENT TEMPERATURES, OR WHEN THE LIGHTS HAVE BEEN ON FOR SOME TIME. EXPLAIN TO THE CUSTOMER THAT THIS IS A NATURAL PHENOMENON AND NOT A QUALITY DEFECT. DO NOT ATTEMPT REPAIRS AS THIS IS CONSIDERED NORMAL, AND IS NOT COVERED UNDER WARRANTY. REPLACING THE LIGHT UNIT WILL NOT CORRECT THIS SYMPTOM.
