Volcano Eye Bike Rear Tail Light (2 packs), USB Rechargeable LED Safety Light for Bicycle, Ultra Bright Waterproof Cycling Taillight,Red/Green/Blue 7 Light Modes Fits on Any Road or Mountain Bike

Review based on just the one light I’ve used so far. Very bright indeed, but for some reason it switched itself off whilst on the back of my mtb. I’ve checked the charge which is fine, there seems to be an issue with the on/off button - which is a bit hit and miss. If the other one works I’ll up the stars, as when it’s working it’s actually quite good.

100 Lumens means that you will be seen from a very good distance by other road users so top Mark's to the manufacturer.The battery is a little short lived however I expected this as it is not very large.The deal at the time of purchase was for two which for a few pounds more over the price of one was a bargain also one has failed due to a fine wire inside coming away from the soldering point so my Brother is going to re-solder it.As I have another one I took the chance of opening it as I have chucked the original package.Quite a few of my workmates have been really impressed with the amount of light this little beauty puts out no surprise then as to the name Volcano.Only one gripe and that is that it switches on really easily if you store it in your pocket or bag so had to store my two in a small plastic container with a little padding.Would I buy again? ABSOLUTELY I'm going to buy another set as I dont want to be a roadkill Pizza thanks.

So good that I had to order another 8 for my cycling friends As soon as they saw how bright and vibrant they were...They have three colours Red,Green and Blue with static or flashing settings.Honestly they are so eye catching that car drivers actually slow down and see you in plenty of time and give you space.It was by chance I seen these advertised and took a gamble...and it paid off.Well worth the money.

Only used once or twice thus far, but seem very secure on my seatpost.Coloured lights are probably just a gimmick, but that's no reason to drop a star.The lights are actually quite chunky, but the fact you get two, and can mount horizontally or vertically, makes up for their size.Only really gripe is that rubber USB cover is a faff.No idea about how often they need charging, but for my intended use I'd likely be charging every night anyway. During winter my commute is in the dark both directions, and an hour long.

Very bright constant light. However the battery on mine only lasts 1 hour max with one unit failing completely after a few rides. Not what you want when you are pumping peddles on an off road. If the battery life was many hours I would give 4 Stars but I don't need to worry if I'm visible and have to keep checking. Poor tech, ok mounting. Try another brand.

Wonder light, warning all cars in the area these are bright.Normally battery needs charging after 1 week 5 days x 30 mins each day.Multi colour lights especially blue for for is a great option.Upgrade your lights if older than 2 years things have moved on.

Excellent piece of kit, very bright , got one on bike and one on helmet. Wish more cyclists used these. Or any lights would be better than none at all?

Super Bright!!! Amazing Volcano Eye lights. Comes in 7 lighting modes. Very bright and efficient. I attach it to my cycle helmet. It lights up like a Christmas tree. Very pleased to buy these lights. For night riders, buy these lights and stay safe.The lights last for days, very efficient. The best thing about the lights is that you can switch to red and blue colour, just like police lights.
