Before I bought the Varia, I didn't think I needed radar. Now, I'm convinced it makes my riding safer. It is solid hardware and works very well in real life.

Garmin Varia Radar RTL515 Rear Light
Staying safe on the roads can be a concern, especially if cycling on busy roads or during long solo training rides. The Garmin Varia Radar RTL515 Rear Light promotes an extra, comprehensive level of safety to the rider via its advanced warning system and bright light combination.
Attached easily to the seatpost, the neat and discreet Varia RTL515 unit holds a rear-facing radar system that communicates wirelessly to Garmin Edge computers, compatible smartphones and other, select Garmin wearables. When paired with these devices, visual and audible alerts are emitted to notify that a vehicle is approaching from behind. Vehicles up to 140m away are detected to provide ample prior warning that extra attention and responsible road positioning is required imminently.
The rear-mounted Varia RTL515 unit also houses a rear light that has multiple brightness levels to suit the riding conditions. Of particular note are the day-flash and peloton modes with the prior providing an extra bright flash for daytime riding and the latter a low, eye-friendly beam for when cycling in a group.
A robust external casing and an IPX7 waterproof rating complete the unit by ensuring durability and reliability within even the harshest of riding conditions.

What type or charger cable is required
Hi there, The RTL515 charges over Micro-USB, and a Micro-USB cable comes in the box, so any standard Micro-USB lead works as a spare. Many thanks Joe W
Can this be mounted to a topeak saddle bag (clip mounting ) instead ot a seat post. And do you sell such mounts ?
Hi there, No this cannot be fitted in the way, Many thanks Joe W
Does this product have a mounting for aero seat posts or does that need to be purchased separately?
Hi there, This is sold separately, Many thanks Joe W
