Two 4 inch (10 cm) red single faced lamps are mounted behind the rear seatback to be viewed through the rear window. The lamps work as auxiliary turn signal lamps, stoplamps and hazard warning flashers. The wire to each lamp is extended to a loop with yellow (left) and green (right) wires coiled in the passenger's side footwell. These loops allow customer installation of an in-line switch in each lamp circuit to disable the auxiliary lamp feature.
