Right now I have a mars 2.0 front head light with the red mars click rear light. The front light is a great "to be seen" light, but it provides very little light so I can see during the night. As far as the rear light goes.. well.. it sucks. It's very small, it's not very bright, and the clip has already snapped.
I am looking to spend about $75 on a light set. I hear the cherry bomb is a great rear light, but I am not sure which front light to get. The trail I ride on is about 15-20 feet wide with dark trenches on the side. I might just buy a front light and stick with my rear light if that lights up the trail so I can see the road and the trenches.
