Hi: The Motorcraft replacement halogen bulb for the laser light bar is stocked at a Ford/Mercury dealer as
part # CLB 2040 it is used on the Mercury Sable years 1992, 1993, 1994, 1995. There are 4 of them required in the light bar.
Replacement instructions:
1. Allow bulb to cool.
2. Disconnect power cord from back of housing. Turn base counter-clockwise and withdraw from housing. Dispose of used bulb with care, this is a halogen bulb and is gas pressurized.
3.
When installing the halogen bulb do not touch the glass with your fingers, hold the bulb firmly with a small cloth. Install replacement bulb by grasping plastic base and inserting into plasdtic cavity. Base must be matched to cavity shape when inserting. When fully inserted, twist gently but firmly clockwise to lock in place.
4. Reconnect power cord.
Hope this helps...good luck
