I  have a round Cibie light mounted on the rear bumper with a switch
at the dash so when I back up - that sucker lights up everything back
there! This van used to belong to Unca Joel and he installed that little
goody. And I love it. Makes backing at night so much easier!

Jostling a loose wire can cause such a problem. A defective switch or bulb can similarly give those symptoms.
