3-Mode 2-LED Red + White Light Tie-On Bike Light Keychains - Black (Pair / 1 x CR2032)

Pros: The material is very good, its rubber and I'm pretty sure it will have no problema with rain or mud.
The leds are very bright and the beam is wide. It's visible from a very long distance.
Has 3 different modes:
Slow, Fast and On.

Cons: Could be cheaper.

Other: There are other sets of lights out there with more leds and some are even cheaper than these but in my opinion these are the lightest I've tried so far and they work very well.
I totally recommend this item to anyone.

Pros: Rubbery body (check cons)
Good price
Easy to operate
Can fit to anything (currently, front/white one is around my headset spacers to keep handlebars free)

Cons: The body, while being made of rubber, seems to have poorly glued joints. So far, no problems here, but I hope they wont break after taking out batteries a few times, or removing them from bike.
Red light has strange color (more like orange)
Came dirty/dusty

Other: Buy them if you need cheap signaling LED-s.

Pros: Cheap and resonable light output. 3 modes (fast blinking, slow blinking and on) Really simple! Just strap them on and go. Feels like they are pretty well built (except for one thing, will get to that later). Unlike others my red is red, not orange. My white light is white.

Cons: My white light is kinda broken. The battery moves inside of it so that it stops working. Probably easy to fix but kinda of a bummer.

Other: Very easy and simple lights for the bike. Just buy it and strap them on. No screwing or fixing a mount. Simplisity.

Pros: Very compact size and light weight. Silicone looks fine, great fitment. Pair, Red & White leds. 3 modes: Fast strobe, Slow strobe and steady on.

Cons: None I can think.

Other: If you night-ride in traffic, this will help you to make you more visible to other vehicles. It's not a flashlight, just a signal light to advert other riders and drivers your actual position. GREAT STUFF

Pros: ++Front and rear light in one package ++very easy to use (3 modes: fast strobo, slow strobo, still) ++because of silicon band, you can place it whenever you want (just use imagination, it not only hold on your bike) +It is pretty bright +it's too small and cheap to be stollen from you bike +I think the battery could hold maybe for 4 to 6 months for not constant use.

Cons: --Build quality is not good --silicon cover of switch will break after time --Changing battery will be nightmare -Not very known type of battery -Hard to fit to thicker bike frame

Other: I have bought four of these and I am still satisfied.

Pros: Price is good, they are bright enough to make you visible on the road. Installs easily to thin bars.

Cons: Quality is poor. Silicone has many defects. Straps are short, so it's difficult to attach light to 31.6mm seatpost. After they came to me, button on the white light didn't work properly. Reassembled,cleaned. Also button isn't clicky. Lights turns off after small impacts, because battery holder is poor.

Other: SKU 51737 are better quality, maybe you should check them. But they are less bright.

Pros: Front one fits the head tube OK and can be fastened with a cable tie (for bettering the chance of it being there when you need it!) Not to many insane modes (could do without the slow blink though ;-) Effective light - also when not seen directly from ahead/rear... :-)

Cons: Need a spacer to not point upwards if mounted on the head tube. Same goes for pointing downwards when mounted on the seat post. Kind of blinding to the rider without shielding or painting the top of the lens.

Other: Will make you seen! Great value!

Pros: Sometimes we have to use this type of light signaling during the day and then she has to be very visible. The battery is included with the product.

Cons: Because I'm importing and waiting several days to receive, I found the price a bit high, because in my town has some similar with slightly higher prices. Thus, the difference I could have bought here too. The battery that comes with the product does not last long.

Other: Despite finding that could be a little cheaper I recommend to everyone because it is a good product.

Pros: Really easy to install in your bike. The elastic strip adapts to all width. For MTB the frontal light must be forced but is not important because don't broke easily. Resist water very well and works after a hard storm...

Cons: You must to put a little paper or similar to push the battery with the cap. If you don't put it, when you start your route the light can switch off and work intermittently

Other: If you want a simple and cheap lights to your bike, buy this one. It's going to be perfect.
