Blackburn Quadrant and Mars 3.0 Combo Bicycle Light Set

Great product. I commute on my bike on dimly lit streets, and they do a great job of keeping me visible to cars. These light are eye-catching and very bright. They are sturdy, easy to take on and off my bike, and easy to take apart and fix.

the tail light attach system is not strong enough for mountain biking demands, the hook to attach it broke at third ride. the headlight is too big, the light is dim. The reflections of the leds in the clear front end interferes with your vision.... take a look at the design, the clear plastic allows to spill out the light in a more than 180 degrees, and not to the front,
i don't recommend buying this light

fine and eficient lights to average riding, as in the city as in the woods.

The rear light is great, though I do worry about snapping the clip (mentioned in other reviews - its hard unflexible plastic vs flexible plastic or metal for a more solid build). However, I have issues with the front light:
1) it's HUGE. and HEAVY. bobs up and down a bit because it doesn't attach super tight.
2) the top isn't covered well, and it shines in your eyes at night a bit. not the best design.

I bought this light set about a month ago and am well pleased. The lights are bright and battery life is good. I haven't yet replaced the batteries and I use the lights about 15 minutes each day. The only problem I've had is the front light is loose on the handle bar and wants to turn up. This should be easy to fix with a rubber strip.
I passed a police officer (he was stopped) this morning and when I saw him later, he said he could see my light good all the way to the top of the hill. He said it would be hard not to see it.
