You can use your multimeter to check the switch for continuity and dis-continuity, when the switch is depressed/released. Or you could just apply 12V directly to the brake wire and see if that lights them up. If the switch is working, then I would check the wiring to the lights. I would also make sure that the brake light circuit is properly grounded. HTH Cory '90 Syncro Westfalia
