PLASTIC HEADLIGHT ASSEMBLY WAS MELTED AND BOTH LIGHT SOCKETS WERE BURNED BLACK. THIS HAD SMOKED ON DIFFERENT OCCASIONS. BULBS BEING USED ARE TOO HOT FOR ASSEMBLY, AS THERE IS NO AIR VENITLATION FOR THE HEAT TO BE VENTED. I WILL NOW HAVE TO REPLACE ENTIRE ASSEMBLY. WHILE IT DID NOT CAUSE A FIRE, IT COULD HAVE BEEN A SOURCE OF IGNITION SINCE THE PLASTIC HAD MELTED AND WAS ACTUALLY TOUCHING THE BULB. LUCKILY, THE BULB BLEW AND A FIRE DID NOT OCCUR. *AK
