davewarwick1 , I too found the OEM PLASTIC lights useless on my 2000 QC, with a low wattage bulb. No replacements available. I upgraded to PILOT PL-119C I got from a local trucking shop, but Auto Zone Web Page says they carry it. I paid $82 for the kit. Exact match size wise for the airdam, 4 inch round glass with 55W halogen bulb which can be upgraded. Good wiring harness but not the factory switch, so i just spliced into the original light harness to use the existing dash switch. The mount brackets it had however was not what I expected, so I modified the OEM bracket to hold the new housing. It worked great,
and the lights are BRIGHT!!!!! Oh yeah, They also have AMBER glass for FOG light use. I took some pix of the mod and put them on my homepage:
