KIT-R1 Rear Bike Lights USB-C Rechargeable LED Back Taillight 18hr Max Ultra Long Run-time Cycling Safety Flashers Blinkers 4 Light Modes (2 PACK)

Unlike my previous, almost identical, rear lights - these recharge by USB C cables, not micro USB. They have the same choice of flash patterns, and attach to the bike / trailer by rubber straps (which seems common nowadays, though I'm not keen on that method as the straps seem to perish and fail within a few months). Like my previous set, these lights can be mounted horizontally or vertically; and the strap attachment allows the angle to be adjusted (very necessary when using on my trailer). They click into position, and the "click" seems much firmer than on my previous lights, so I'm hopeful that it will actually hold the light in place at the correct angle rather than flopping downwards when going over bumpy ground! [Update - it does!]The lights arrived almost fully charged. It's too soon to say how well the batteries will last, but my previous cheap lights were still going fine after many months of recharging, and frequent use during the winter months.These lights arrived in a well padded presentation box inside an Amazon envelope, which gave good protection in transit (a cheaper set arrived unpadded in just small ziplock bags in the Amazon envelope. No wonder neither worked when they were delivered!)My only complaint about these lights is the rubber strap attachment. I have severe arthritis in my hands. There is a little lever to press to release the lights from the fitting to charge them, and unfortunately, this lever is so stiff (unlike my previous ones) that I strugged to release the lights (but then again, they're consequently held firmly and don't fall off mid ride, which happened to one of my old ones). But then, it's always possible to remove the whole thing for charging.UPDATEI've been using these lights a lot this winter, not just for night rides, but in foggy / wet daytime conditions too. They recharge quickly and last for a few rides (I'm mostly out for between 60 and 90 minutes per ride). My only complaint there is that, like most of these cheap rechargeable lights, there is no indication of how much charge is left; I worry that they'll fail mid-ride, so I probably charge them much more frequently than strictly necessary ...They're easy to swap between mounting on my bike frame, or attaching to my trailer when I'm towing it. They're definitely bright, and on the double-flash mode give me confidence that traffic coming up behind me can spot me easily!So far, so good, and I can recommend these as good value, effective rear lights.

I'm a powered wheelchair user and I'm often our when it's dark. I use these lights on the rear of my wheelchair (bought 2 sets) and use them as side lights. Very bright and easy to use, recharge quickly, usually 1hr approx. Long battery life, I've have a battery life of 15hrs roughly and at time of reviewing I've used them everyday since July 2024. Attached securely to my wheelchair with the supplied rubber straps. Definitely waterproof, I can 100% attest to that.I've been let down by multiple different rechargeable LED light previously but I definitely recommend these lights.

Great set of lights that seem to hold their charge well, and are fast charging when needed. They can be installed really quickly and I love having two lights for greater standout. There's several flashing modes so I set each to something different.

Super little set of rechargeable rear lights for bikes.Pretty bright, and eye catching if fitted correctly.Easy universal elastic mount system means that these can easily be carried and fitted for use when needed.Why risk not being seen at night when these little gems could save an incident?Very reasonable, hopefully reliable, and a potential life saver for occasions when caught out in the dark,Highly Recommended

Excellent and being long, not round, they can be mounted vertically or horizontally, they give you more light to be seen by drivers. Love the options on steady, flashing or chasing light.

Cheap, works well.

I like the lights

Very bright so we'll worth the money
