Rear LED Bike Light, 3 Modes, Saddle Post & Bag Clip Mount | BTR

Simple, Reliable Rear LED Light for Any Bike
A straightforward red rear LED bike light with three modes, designed to clip onto a saddle post or a bike bag in seconds. If you want a no-fuss tail light that just works, this is it. Perfect as a primary rear light for casual riders or as a spare to keep in your commuter bag for the times you forget to charge your main set. Three light settings let you switch between steady on and two flashing modes depending on the conditions, and the clip-style mount means you can move it between bikes, helmets, bags or jackets without any tools.

Looking for something brighter or USB rechargeable? Take a look at our newer 300 Lumen USB Rechargeable Front & Rear Set or the 500 Lumen Twin T6 Set with Battery Indicator for unlit roads and country lanes. Key Features
Bright Red LED
Clear red rear light visible from a long way back, so drivers behind you have plenty of time to see and react. 3 Light Settings
Steady on plus two flashing modes. Match your light pattern to the road conditions and the rules of where you ride. Saddle Post Bracket
Comes with a fitting that mounts to standard round seatposts so the light sits cleanly under the saddle.

Bag and Jacket Clip
A built-in clip lets you attach the light to a backpack, jersey pocket, helmet strap or jacket loop instead of, or as well as, the bike. AAA Battery Powered
Runs on 2 x AAA batteries (not included). Good runtime per set of batteries, and easy to swap mid-ride if you ever need to. Compact and Portable
Small and light enough to live in a saddle bag or commuter pocket as a backup, even if you already use a primary rear light. Who Is This Light For? Casual riders and commuters
If you mostly ride lit roads but want a sensible, always-on red rear light, this is a quietly effective pick.

Reliable, easy to fit, easy to swap when batteries run out. Backup tail light
A great second light to keep clipped to your commuter bag or in your saddlebag, for the days you forget to charge your USB rechargeable set. Multi-use visibility
The clip means it works on a bike bag, a backpack strap, a running rucksack or a dog harness. Useful for runners and walkers who want a red rear blinker too. Need Brighter Lights? This is a simple battery-powered rear-only light.
