## Description

Shop WASAGA Waterproof Rechargeable LED USB 5 Modes Rear Tail Light (Grey). Free delivery and returns on all eligible orders.

Review: Bright, secure and easy to charge. - A very bright rear light, visible from a good distance even at dusk in one of the pulse modes. It recharges pretty quickly to give a number (it’s not run out after 4 hrs use) of hours’ light delivered in 5 Clear and easily selected modes. Easy to recharge and has a very great clamp/clip to fix to a bike frame, seat stem or back pack...my last light’s weakness and how I lost it. This one is very tight and secure when in place. A very good and versatile light. Certainly value for money.
Review: Excellent flashing LED rear bike light. - Well made, bright, rear, rechargeable red LED light. with 5 settings. Easily fitted to the end of my bike pannier. 5 styles of flashing to choose from. I've opted for the slow/medium strobe effect which maximises battery life between charges (about 35 hours). My only criticism is that the USB charging port is micro USB rather than USB-C. USB micro ports and cables are an absolute pain because of the fouter of having to make sure the charging cable is inserted the right way round (which can be a real pain if you're in darkness) whereas the USB-C simply plugs in without having to check orientation. Having said that, a micro-USB port and cable are NOT a deal-breaker. The merits of this tail-light outweigh any criticisms.

## Questions & Answers

**Q: How bright is this light in 'lumens', please?**
A: According to the info on the package, 15 lumen max.

**Q: Does it stay on sadle bag ok ..thanks**
A: The fastener is a rubber strap, fastener is rubber with clip around 27.2 seatpost I dont use saddle bag  , great and reliable so far. the light is good fully charged for 3-1/2 - 4.0 hrs they are cheap enough to run with two in evening or late afternoon.   Watertight for the damp runs i do in dusk dark conditions I can’t comment forain conditions I have used on wet roads with no glitches. I’m pretty confident in the two I use

**Q: Is this a good daytime light? Like those seemingly as bright as car fog lights?**
A: It's is bright, but as car for lights. No not that bright.

**Q: Hi, may i know how much is the battery life? And which mode consumes the least battery?**
A: The battery lasts a very long time. Better than any previous lights I've had. I use it on one of the flashing modes and commuted 18 miles a day throughout the winter. Honestly, it only needed charging every couple of weeks. I never used it on solid light mode but this would no doubt use the battery life quicker. This light is certainly the best option I've experienced over many years of commuting. Hope this helps

### ⭐⭐⭐⭐ Great lights with a couple of minor caveats
*by A***A on 15 December 2020*

Cute little tail lights that are plenty bright and with good battery life. They have several flashing modes (though they can't emit a solid beam) and seem to be fine in wet weather. They're easy to mount on bags and clothes with the built in clip, or you can wrap it around a post with the supplied adaptor. That also makes it easy to remove though, so if it's on your bike you'll find yourself having to detach and reattach it whenever you lock your bike up somewhere. We bought a couple of these, though one had a fault. It was easily replaced though and they've had no problems since. They are reasonably well built, except for the rubber USB cap which could be a tighter fit to help the weatherproofing longer term. Overall good lights
