Universal saddle-mount bracket for Garmin Varia rearview radar and tail lights Why this mount matters Keeps your Garmin Varia radar/tail light positioned under the saddle for better visibility and protection compared with seatpost mounting. Securely holds the device in place during rides, reducing vibration and movement so the radar and tail light work reliably. Made for riders who want a neat, low-profile installation that protects their equipment and increases safety. Key features and benefits Compatibility: Designed for Garmin Varia RVR315 Rearview Radar, RTL515 Rearview Radar Tail Light, and RTL510 Rearview Radar Tail Light. Fits most bike saddles with a two-rail (two-stick) design. Safer placement: Mounting under the saddle positions the radar/tail light behind the rider and away from impacts on the seatpost, improving protection and reducing the chance of damage. Durable material: Manufactured from reinforced nylon for strong, long-lasting performance that won’t harm your saddle or device. Stable attachment: Uses four fastening screws to secure the bracket firmly; minimizes wobble and keeps the radar/tail light aligned. Adjustable angle: Allows easy angle adjustment so you can optimize visibility for the radar and tail light depending on bike geometry and riding conditions. Easy to install and remove: Supplied with the necessary tool; quick installation and removal for maintenance or when switching bikes. Practical use scenarios Commuting: Attach your Garmin Varia RTL515 under the saddle for a protected, permanent rear light solution that stays visible to traffic during morning and evening rides. Group rides and training: Use the RVR315 radar mounted on the bracket to monitor approaching vehicles from behind while keeping the unit stable on rough roads. Night or low-light riding: Combine the RTL510/RTL515 on this mount to keep a reliable tail light low and centered behind you, improving visibility for drivers and other cyclists.
