I should have specified. The back-up lights only turn on when in reverse mode. The second problem I ran into with the lights I ordered was that the LEDs do not turn on when the parking lights were switched on. These LEDs only comes on when break is applied. The bulb that I currently used is similar to the stock bulb for the break light (with a blue coating). The bulb with 2 sets of wires inside (one for parking, one for break applied). I need an LED with dual light (one for parking and one for when break is applied). Any ideas?
