I have been happy with my Night Rover, enough to buy a "backup" system. The switch failed on my first system, and they offered to sell me a new case, included a new switch, for a modest fee. The battery life is short if both bulbs are used. So, I installed a ten watt bulb, and use it by itself, and get about two good hours per charge. For whatever reason, a ten watt bulb in the Night Rover case seems brighter than one might expect.
