## NHTSA's summary

SERVICE INFORMATION: CONDENSATION IN EXTERIOR\-LIGHTING LAMP HOUSINGS: VAN HOOL REGULARLY RECEIVE QUESTIONS ABOUT THE PRESENCE OF CONDENSATE IN EXTERIOR\-LIGHTING LAMP HOUSINGS. THIS SERVICE BULLETIN EXPLAINS THIS NORMAL PHYSICAL PHENOMENON. EACH LAMP HOUSING CONTAINS A QUANTITY OF "TRAPPED" AIR. THIS AIR CONTAINS WATER THAT IN HUMID OPERATING CONDITIONS OR SUDDEN VARIATIONS IN TEMPERATURE \(E.G.: AFTER CLEANING IN THE WASHING BAY\) CAN CONDENSE IN THE LAMP HOUSING. THE CONDENSATE PRESENTS ITSELF IN THE FORM OF MIST OR SMALL DROPS OF WATER THAT SETTLE ON THE COLDEST PART OF THE HOUSING. MOST OF THE TIME, THE PHENOMENON OCCURS WHEN DRIVEN THROUGH RAIN FOR A LONG TIME OR STORED FOR A LONG TIME AT LOW TEMPERATURE. NORMALLY, THE CONDENSATE DISAPPEARS AFTER SOME TIME WHEN THE VEHICLE IS USED IN DRY SURROUNDINGS.
