how it works

The RVR315 isn’t equipped with lighting. If you already have a light, this is a good option. My recumbent trike, for instance, has lighting built in. My wife’s e-bike does, too. And my urban bicycle for getting across the city.

Simply hand me the binoculars and consider it a day. However, the RVR315 only has a 7-hour standby time. The RTL515 will set you back $199, while the RVR315 will set you back $149. The RTL510 (the earlier model) has been on sale for $129 USD for the last few months.

Using Varia as a tail light 

Tail light

Sure. The Varia RTL510 and RTL515 may be utilized in this manner, but not the RVR315 (due to its lack of a rear light). You may use the RTL510/515 as an ANT+ light and an ANT+ radar unit at the same time. This has the effect of providing you to manage it through the ANT + illumination command center, allowing you to get the device turned on and off immediately whenever you switch down the brightness of your Garmin.
