Bresuve USB Rechargeable Bicycle Tail Light, Super Bright Led Bike Bicycle Rear Light Automatic on/off, Brake Induction, IPX6 Waterproof, Red high-intensity LED Bicycle light for Mountain Road Bike

Love the light but had a problem mounting it on the saddle. It points down a bit. I have seen another version with a seat rail bracket and rhink this would be better, trying to contact supplier to see if I can just buy the bracket

Nice light, easy to fit and bright. The only issue with the saddle fitting is the amount of rail available. Couldn’t fit to my road bike but used in my hybrid instead. The automatic mode works well.

Absolutely love this rear light, it’s bright enough but not dazzling to motorists behind, it has a good array of flash patterns and the flare under breaking is superb.My main reason for the purchase though was the way it mounts to the saddle rails, the bracket just zip ties to the rails and the light screws into it perfect for a mtb dropper post.The hole thing is machined aluminium & and there’s an O ring seal so water can’t get in to the charging port or the master switch, the master switch is to set the light for manual on/off or auto where the light comes on with movement, the light also has a daylight/nightlight sensor so it’s brighter during the day but lowers the intensity at night.My use has been limited but so far I am super impressed with this little light.

Some serious quality issues with these lights. There are many different "Brands" but they all seem to be the same light the Xlite 100. Great in principal, the light works well and goes brighter when it senses that you're slowing down. Unfortunately, the 3 that I've bought have all failed (thankfully within 30 days, so returnable) Issues include, inability to charge, and the centre button stopping working.

brilliant product let down by rubbish service. The light lasted 5 months working perfectly then instantly stopped working. Tried all the usual stuff - charged up, properly connected etc- nothing! Contacted (Chinese?) supplier for replacement and 24 hours later got a lame excuse they needed me to make and upload a video for their supplier before they could do anything. All this for a £16 lamp! Told them no as they requested it was sent to a 3rd party address and to get on with my replacement as I use my bike twice a day to commute in the dark. Got another reply a day later spouting policy etc.. very poor indeed and not how it works in this country. Never had an issue like this connected with Amazon. Watch this space for updates

Was OK wile it worked, but stopped working after 2nd recharge. Supposed to have a 1 year warranty, but manufacturer is not replying to emails. Buyer beware.
