Tried out the Night Rover last night on a local trail called Panorama. Surprisingly these lights are really bright!
The dual beam system is small in size but the output is amazing much like other light systems that cost twice as much.
I tried out both HI and LOW beams individually and combined, these babies lit up my path so well, that I didn’t have to worry about any unexpected surprises on the trail.

I also liked the feature on the unit because you can pivot the lights 5 degrees to the left or right. This helped offset the riser on my handle bar. I also thought that the battery pack was not heavy at all. Fits right into my water bottle cage. If I wanted to, I could upgrade my handlebar mount to helmet mount for about $18.

My overall rating for the lights: I highly recommend them to everyone. I also do not have any regrets for my purchase. I believe you will be satisfied with them. As a matter of fact, 2 other guys on my team have these lights and because of their recommendation, I’ve purchased my own set.
