Q: I have a unity light that came installed on a 2000 Crown Victoria PI, it's mounted on the left side and there is a screw missing on the outside part of the light and looks like it might have been used to tighten a clamp that holds the spotlight to the shaft. I need that screw and also when the car was taken out of service, the wire under the switch was cut off flush and I need a new wire and switch or handle assembly which ever is easiest to replace. I really would like this light to work as I drive at night for a security company. Are these parts available and could you suggest the right part numbers?
A: It sounds like you are talking about the screw on the head housing. The head housing is the chrome piece that goes between the head of the light and the shaft. The screw comes through the side of the housing close to where the shaft goes into the head housing.
If that sounds like the right part the screw is U-6040-A
Switch and wire is 6453-0001
Replacement handle is U-6701-0101
If you don't mind some minor cosmetic issues
Z-6701-0101 is the same handle and is a much better deal.
