Review on Birdi Disc Golf - Flat Circular LED Lights for Night Disc Golf - 8 Pack (Multi) by Daniel Ogbebor

Good at first. These lights are bright and if you clean the disc before applying the light they will hold up pretty well. Now for the bad. The batteries don't stay in the mount, which means your light could go out if you hit a tree or something else. I solved this problem by applying a small dab of hot glue to the top of the battery and it made a world of difference. You can also bend the tab on the bracket to improve contact with the battery. Overall I would recommend these lights with the caveat that they need a bit of modification to work optimally.
