[FC] backup lamp question

[Dale Dewald]

Hello Ken,

I like the idea of using switched ground, but the type of lights Tim is 
using may make this impossible.  If I recall, these B/U lights are like 
tiny fog lamps and would logically be mounted to the bumper. There is a 
single pigtail power lead to the bulb center contact. The circuit is 
completed with the bulb socket grounded to the metal lamp housing, through 
the bumper, and to the car body.
