i had them on my bike, and i helped put them on my friends bike. he likes them a lot, they were cool for me but then when i was doing my winter cleaning i pulled them off and just decided to not put them on again. they are pretty bright if you put them in good spots, i think the usual is under the tail, under the front and in the side. i would recommend getting the power module, makes it compact and easy. plus it lets you plug everything into that, while you still only have two wires going to the battery. o and one more thing, i would get the flexi strips over the solid mounts, if you plan on getting those long strips of led lights.
