Reverse lamps are not bright. Camera does not brighten area either. Very unsafe to reverse in the dark. Have to touch the brake pedal to be able to see while backing. Also have tried the leds in the mirrors while backing- although the leds are bright- lights to see while backing are insufficient on the stop lamps.
