Bike Bar-End Red Lights - Black + Red (Pair/2*AG10)

Pros: Bright lights, great for kids safety when riding at night

Cons: 1 Way too sensitive, flash even when neighbouring parks are jogged a little
2 Cannot push them all the way into my son's handlebars so stick out quite a bit
3 I had to fiddle with one to make it work initially
4 As mine stick out quite a bit, I'm not sure how long them will last if they are used to rest the bike against walls, etc

Other: Pretty good, all round

Pros: Light is bright, and it starts automatically as soon as I touch my bike. The assembly looks quite solid so it should last at least over the winter.

Cons: It might be a little too sensitive. I hope it does not light up by the wind. And the batteries used (AG10) are ridiculously small. There is a lot of space inside the handlebar, so I would have preferred slightly larger batteries.

Other: A cheap buy that can save your life. How much is it worth?

Pros: Very bright lights, that are always there if you forget to pack a light. Nice additional light, lets cars know exactly how wide you are while riding, making them give you a bit more space.

Cons: You can't turn them off, there is really no reason to run them during the day time. Also sometimes due to the mechanism they were not lighting up. Maybe this is more a compliment to the smooth ride of my fixy than the lights themselves. Had the cover fall off a couple times

Other: If you are looking for a handlebar tube light, this seems like the best ones I've had from dx so far.
