2-LED 3-Mode Fog Bicycle Light - Red (Pair/2*CR2032)

Pros: Very bright. Small. You can attach it to more than just a seat post etc... as long as you can stretch it. Ive mounted mine to bungee cords without any problem.

Cons: Will only really fit round objects that are thick like handlebars and seat post etc... But can fit loosely around bag straps if you make sure there is enough tension.

Other: Good back up lights, could be used as main rear light if you used 2+ off them. You can also put these on your hubs if you want to make yourself more visible, recommended, as it does make you stand out quite a bit.

Pros: They are bright lights, and can las for a very long time on the batteries. Not sure exactly yet, but Im assuming at least 50 proabably closer to 70 hours. Easily attach to any 1 inch diameter bar or post, but you can get inovative and try wraping them on other things too, like your helmet if you can find some vents that work.

Cons: They are somewhat bulky. Trying to push the button to turn them on and cycle the modes is difficult. In one of the two lights, the LED leads that conect to the circuit board were too long, and didnt give a proper fit or a proper light as a result. I was able to fix it easily enough by re-soldering them.

Other: About 1/4 the price as store bought ones. The quality is good enough for the weather though, and they do produce enough light. get some extra batteries for them here while you are at it, These are great little lights.

Pros: -Comes in package with 2 (in case you loose one)
-Comes with batteries
-Very bright light, good visibility on the road and at night
-Inexpensive, most cost double the price for one
-3 modes, fast blink, slow blink, constant on
-Strong fastening

Cons: -Took a while to get the lights
-Plastic strap is thin so will wear out or snap if abused

Other: Great Deal, really can't beat the price, especially for 2 of them. Very good for a little security and to get your bike up to night riding standards.

Pros: It's ok, I have very similar item for a long time and it's very useful. It's lightweight and easy to install and uninstall from bike. Also you can install it whereever you want on your bike, not only under saddle like other lighters do.

Cons: The silicon can break if you setup it to bike very often.

Other: I recomend to have it. It's useful, light is visible and your ride will be safe.

Pros: I have mounted the lights on my bicycle. It works fine. I am riding Cross-Country in a dusty area and it is still working fine.

Cons: One of the lights has a "hard" on/off switch and it is harder to operate than the other. Plastic strap is thin I am not sure how long it will hold especially if you will take it on and off the bicycle.

Other: Very good for what I use it for. Can be seen at night.

Pros: Works perfect, easy to attach to the bike, and I use it for my dog. 3 attached to the collar and the dog is like a police car chasing rabbits in the dark.

Cons: One of the lamps was turned on at arrival, so the battery was almost empty.\ The battery is behind a sticker, so after changing the battery the unit will not be as water proof any more.

Other: Works OK, nice bright light.

Pros: It is very bright. Looks waterproof (but haven't tested yet in heavy rain). Fastening is very secure and holds well. The lamps have several modes, so you can put them on blinking to both improve visibility and save battery life. Uses standard CR2032 button batteries which you could get for cheap at DX. And you get two pieces for ok price!

Cons: None really. Could be a little cheaper maybe.

Other: Get them if you move out at night.

Pros: Its awesome, its small, its easy to put on your bike. In summer when i am cycling late on the day i use these on my racingbike. Because they are small they can easely in the bike bag..... and cheap enough to buy another pair!

Cons: Some lichts are shining trough the silicon chase, but if you put the licht upsidedown you don't have that problem.

Other: Just two words. VERY USEFULL!!!!

Pros: - Easy to use - Very light - You can put it in many bike parts, backpack, helmet, etc . VEry visible from a considerable distance - Great for street use

Cons: - I broke one trying to adjust to a very big tube, but it was my fault. - The batteries that come with the product are not full, so you ill need to replace them for new ones in al short period. But the new baterries are great for it!

Other: I recommend it! but I would recommend also to buy extra baterries
