Red Light 2-Mode Tie-On Bike Light Keychains (2-Keychain Set)

Pros: Having tried just about all the other wee tie on lights/back up, in my opinion these are the best.
They are a bit bigger than the usually one's, thats because of the lens which really helps to magnify the out put, and because of this, these are the only one's i would consider using maybe 3 as the main back light.
It has a nice solid click on/off switch.
It only has two modes, flashing and steady on.
Im guessing the run time is similar to other smaller lights, as this uses two batterys instead of one.

Cons: Water can get into it though if the rain is heavy enough, or if there is direct spray coming from your wheel, as it will eventually force a few drops through! You can seal it up by running a bit of silicon around the edge between the clear plastic and the white plastic, and this does the job.

Other: To sum it up -
These are better overall than any other wee light on DX so far.
Get these and dont waste your money on any of the others.

Pros: -Small size;
-Very bright for such a small size;
-Easy to mount almost everywhere - on the bike, on the bars or even on the backpack. There cannot be too much safety lights - I use 4 red blinkers when riding at night.

Cons: -A bit pricy, IMHO;
-Might be not waterproof (haven't tested them yet, though).

Other: Very good bargain. Every cyclist must have minimum a pair of these blinkers.

Pros: I use a bike a lot on streets and also at night, returning from work/classes. This and sku44096 were perfect choices to attach lamps on my helmet (Wich I prefer, since that is a more visible position to put lamps when biking). I've submitted also a video showing both on the helmet. - Good quality - Can be easily attached to different places. Including helmet

Cons: None that I can really see for now. Looks a little bit more fragille and less water resistant than sku44096, but its fine.

Other: Good product, good quality, good price.

Pros: Cheap light, works fine and is very bright. Easy to intall - no tools needed. Barata, funciona bem e tem brilho intenso. Fácil de instalar - não há necessidade de ferramentas.

Cons: Bought two of each - white and red. One of the white ones was not working when arrived. Changed battery and it is ok now. One of the red ones worked for a week and the battery ran out. The batteries are not good so make sure to order spare ones here in DX (two for each light). Not waterproof at all - got a rain these days and one of them stopped working. Back again when dry. Comprei duas de cada - branca e vermelha. Uma branca não estava funcionando quando chegou. Troquei a bateria e está ok. Uma das vermelhas funcionou durante uma semana e a bateria acabou. As baterias não são boas então seria aconselhável comprar algumas extras aqui no site DX (duas para cada). Não é à prova d'água - peguei chuva esses dias e uma delas parou de funcionar e só voltou depois de seca.

Other: It is a good product for the price paid. The batteries included - two for each - are weak so buy some extra ones (here in Brazil, the batteris may be more expensive than the product itself...) Make sure you won't get any rain... É um bom produto pelo preço pago. As bateria inclusas - duas para cada - são fracas então compre algumas extras (aqui no Brasil as duas baterias podem custar mais caro que o produto...) Não pegue chuva...

Pros: Very nice! Love it. It is very bright and easy to strap on handlebars, helmets and other parts. It is light and the batery will work for days of continuous.

Cons: It is not waterproof. It may manage to work in rain, but you cant throw water directly on it. Once it is wet, you cant turn off. If it gets wet, open it, remove battery, let it dry and put it all back together. Worked fine for me. Uses 2 batterys.

Other: Awesome buy. I have bought more than 8 that I use or gave to my friends. Still on my bikes.

Pros: Pop in the bubble and turn on this light. Just like popamatic trouble. Maximum diameter of ~ 3.8 cm Minimum of ~ 1.5 cm. Easy to change the batteries and seems very high quality. Not lopsided, like other DX silicone lights and so does not slide down out of allignment. Just as bright as the double LED DX lights

Cons: one out of 4 with dead batteries. The rubber colour may not be discrete enough to prevent theft.

Other: better than the lopsided DX lights for vertical bar attachment.

Pros: Excellent lights with a powerful bright. Not recommend to have the light directly to your eyes. I need to check the battery utilization. However, until now, I didn't have the opportunity to use these lights for a long time.

Cons: One of the lights came without power in its batteries. No more cons found.

Other: I recommend this product. Cost/Benefit is good. Materials seems good.
