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

I bought one for my ebike, but had to make a custom plate to mount on my bicycles rear rack, as I have a rear box that blocks installing under the seat. I liked it so much I bought a second one. They look and work great when I'm riding at night. I need to update this, after a week one of the lights no longer shuts off automatically. It works fine on manual, but I did like the convenience the auto off provided. Still a good deal, and the brake stop light function works fine, drawing favorable comment two times now.

I have a beautiful bike and haven't wanted to clutter it with ugly attachments. But obviously a good taillight is essential. The XLite100 fits the bill perfectly. It's small enough to tuck under the seat, bright enough to be clearly visible from far away, and smart enough to turn itself on whenever the bike moves, to sense when braking is occurring and function as a brake light, and to turn off when the bike is no longer in motion. Plus several more convenient features. The USB charging port is weather-protected. Access for charging couldn't be simpler. I can't speak to long-term durability yet, but I have high hopes. This is a beautifully designed product!

This product does not actually flash on and off but rather slowly dims and brightens when in use. Each of these settings holds for several seconds before changing back. This means that when you brake the cars don't know because it registers as a regular brightening of the light. If it were flashing on and off, as in the videos that I saw, then the flashing stopped for the bright light, that would signal a braking similar to a car's brake light. Close, but no cigar.

I really like this little tail light, auto everything to do with safety. Only thing not automatic is the charging. It does need to be removed from mount to be recharged, but no biggie.Auto & manual settings gives a rider plenty of choices.

I liked that the light was extremely easy to use and simple to mount. I would prefer that the unit came with additional mounting hardware in case I wanted to switch it from the seat base attachment included to a shaft or tube base attachment.

its awesome!! I installed it on the seat.

I bought this product and it worked great for about two months but now the unit has stopped working.

Installation is as easy as it gets.

Great Product, this light is Brilliant.

la luce è abbastanza intensa e luminosa ed evidenzia la frenata come descritto. ma nel mio caso non riesco mai a finire il giro con la luce accesa, arrivo a casa che è sempre spenta e non perchè scarica, infatti riaccendendola ci resta finché non la spengo. Insomma non sono proprio soddisfatto.

Fonctionnait très bien le 1er mois mais depuis le mode automatique ne fonctionne plus et le mode manuel commence à avoir des ratés
