2-Mode 5-LED Safety Bike Tail Light with Mount - Red Light (2*AAA)

Pros: Cheap
Easy to mount on seatpost
Snaps fast for removal when you dont need them
Good visibility
Can be used on belts, bags, backpacks etc.

Cons: The biggest con I have with this tail light, is that they came scratched and dusty.
I can understand they cant be pristine clean, but having 2 noticeable scratch marks across the whole plastic cover is simply not acceptable.
Will post pictures soon, but I dont know whether I should send message to DX customer service or not, because it is clear this light was used and abused :/
Beside that, they can be a pain in the neck to open up and replace batteries.

Other: Decent tail light, but to be sure - buy another similar one here on DX.

Pros: - Bright and long range visible - Cheap - Good plastic body - Easy to fix, quick fit system - Comes with accessory to attach to your belt or pants - Waterproof (not tested)

Cons: No screws. The lens is attached and can be opened by hand.

Other: when not used, it is a good toy for children.

Pros: It has very bright and good visible light. The build quality is good build and it is really easy to mount (without screws). I use it for few months and the battery life seems to be excellent (much better than with light I've used previously).

Cons: I don't see any, maybe mount could be more robust, but I did not have any problems with it so far.

Other: Great value for the price.

Pros: Two mounts - a belt clip and a bar attachment. It can be swapped fairly easily from one to the other. It can be mounted vertically or horizontally. Solid construction, not flimsy.

Cons: Three modes is still at least one too many. Can't turn off without looking at it.

Other: Solid light. I'd buy it again. Probably will, since I have a tendency to lose them, and thieves grab them too. Get one for the bike and one for your backpack.
