This review covers both this flashlight and the NV5081. I'm not sure if the reviewer at GA mentioned the tail/running lights not being bright enough for daytime use. Maybe the set you received was defective? The pair I received and the brake lights and turn signals are very BRIGHT! So bright that my friend commented that "people" complained that my taillights were too bright. During the day the rear light/running light doesn't bother me. When my light is on, it's dark. :) You'll need a ground eye and a few connectors to install them, but the wiring is pretty easy (3 wires). Regular running/tail lights are visible from behind, but I've found that they don't jump up if you look directly at the light from above. Since I don't expect space invaders to hover over me, I don't care. Can't tell if they're waterproof as they weren't trailer mounted for my application.
