Serfas Thunderbolt 2.0 50 Lumens Rear Light Reviews

3 Rating 1 Reviews
It's very bright, but sometimes it won't turn on. You think it's turned on, but get to the end of your journey and discover you've been riding in the dark without a light! It comes on and turns itself off within seconds. When it works, it's great.
