I get really scared when I back up at night (recall in Newbury we have no street lights, nor side walks, nor stoplights for that matter) anyways, it's very hard to back up.
In our Bravada however the back up lights, light up the neighborhood when you hit the keyless unlock button. They stay lit for over 10 seconds, it's kinda freaky like head lights.
If you don't like them then disconnect them (well unless it's the only reverse light, which might be its main function)
