THIS IS A 5-3/4 INCH ROUND CRYSTAL HEADLIGHT. IT REPLACES H5001/H5006. IT HAS A RUGGED ANTI-VIBRATION CONSTRUCTION, WITH REINFORCED DIE-CAST ALUMINUM REFLECTOR. IT USES AN HALOGEN BULB, SAE-9007. IT COMES WITH THE 9007 BULB CONNECTOR/ADAPTER. WE INSTALLED THESE IN OUR 1985 359 PETERBILT. THE ONLY PROBLEM WE HAD WAS THAT THE HEADLIGHT HOUSING DID NOT PROVIDE QUITE ENOUGH ROOM FOR THE ADAPTER PLUG. WE USED A HOLE SAW AND MADE AN OPENING FOR THE PLUG. THE LIGHTS WORK REALLY GREAT AND HAVE INCREASED OUR NIGHT VISIBILTY. NEW. EACH. |
