Trek CarBack Radar Rear Bike Light

Helps drivers see you

Enjoy best-in-class visibility with an interruptive flash pattern that’s daytime visible from up to 2km away.

Helps you see cars

CarBack Radar can detect rear approaching vehicles from up to 240m away.

Visible battery gauge

A four-bar LED battery gauge makes it easy to read your battery status.

Waterproof USB-C charging port

An IPX7 waterproof rating helps ensure trouble-free operation in all conditions, and the USB-C port makes it quick and easy to charge.

Compact design

A smaller profile makes it easier to mount CarBack on smaller frames and with saddle bags.

Universal ANT+ connectivity

CarBack pairs with most major cycling computers, so you can use it with the GPS head unit you already have.

Smart phone compatible

Connect CarBack to your phone through the Trek Accessory App, which will let you see the position of oncoming cars in real time or get audio alerts from your pocket.

Be seen, and see what’s coming

A single light that helps drivers see the rider from farther and helps riders get advance notice of approaching cars equals more confidence on the road with fewer surprises.
