Varia RTL515 Rearview Radar with Taillight

As functional as the bar and helmet-mounted mirrors are, there is a cost in aerodynamic drag and, for some reason, an insurmountable drag to the image of the road-devoted cyclist. Garmin preserves our pride and taps into some nifty tech with the Varia RTL515 Rearview Radar with Taillight, that packs significant features into a small package. Fitting onto most road bike seat posts, it tucks out of the way and is a rear-facing, red light flasher with a built-in automobile radar feature.

The standard bulb modes are found here with 20 lumens on solid beam, 29 on night flash, and 65 on day flash, however, the Varia sends it over the top with a courteous peloton specific mode with 8 lumens of brightness. So keep your group ride safer without creating frenemies along the way.

The Varia's primary feature is the radar that picks up traffic headed your way from 140 meters behind, and relays that information to your Garmin Edge bike computer or Varia app on a smartphone. The "car" shows a relative distance to help you judge proximity and gives you time to make lane adjustments or turn corrections. And the bulb provides enough visibility for you to be seen from up to one mile away.

Battery life is impressive with 16 hours of on flash mode and six hours on solid, which will see you safely through most training rides.

  • Seatpost mounted taillight and radar provide peace of mind
  • Oncoming car data is displayed to your Garmin Edge computer or phone
  • Proximity display helps you make lane corrections in time
  • Taillight is visible from up to a mile away
  • Conserve battery with various bulb intensities to suit the conditions
  • Peloton mode turns down lights to keep the pack happy

Game Changer for Serious Riders

I've put it through the wringer

My wife and I ride 9 months of the year here in New England and put on thousands of miles and hundreds of hours. We typically rely on helmet mirrors and handle bar mirrors to keep track of approaching vehicle traffic. However we are blessed to ride on many lightly traveled country roads. The Varia for us is a game changer. It picks up approaching vehicles about 150 yards to your rear, notifies you with a distinctive sound and then allows you to see precisely how quickly the approaching vehicle is overtaking you on your bike computer screen or iphone/smart phone or both. It's so consistent and accurate that you gain a sense of freedom and confidence in terms of owning the lane because you know there's no car approaching. And if you regularly use a headset or earphones, (we do) you don't have to keep checking your mirror every 5 seconds because the alert tones always give you plenty of heads up to ease back towards the shoulder. The reliability of the unit is outstanding. As others have noted, once we started riding with the Varia we both felt we couldn't ride without it! The only problem if you're a riding family or couple, is everyone who uses it will want one for themselves! It's that good.


Does this device allow for USB charging?

Hey Mario, Yes, this comes with a small charge cord that works via USB. So it should work with any current charge boxes you have, or more simply your computer!


will this work with a Garmin 510 computer?

Hey John, Yes this will work with any Garmin or Wahoo Head Mount, all you need is the most current firmware on your system, and it will synch right up!

I've put it through the wringer

I agree with Gene D. The best cycling accessory I’ve purchased. Definitely worth the money. I’ve been using this for over a year and it has never failed me. Ever have a car speed by you then make a right hand turn in front of you because the driver thinks he has time to make the turn. You hit the bakes to avoid T-boning the moron. Now you can look at your head unit and watch as the car approaches you from the rear and be prepared . Highly recommend.

Buy this now.

I've used it once or twice and have initial impressions

Are you thinking about buying that fresh jersey? Maybe those lighter pedals? New shoes? If you don't own this, stop your browsing for incremental or style upgrades and buy it now. Yes its pricey compared to other rear lights and yes you need a compatible head unit. But chances are if you're shopping here you own a head unit already. Paired quickly and easily to my Edge 530. I took this on the first ride yesterday. Its uncanny to have eyes in the back of your head. It detects cars easily 10-15 seconds before I can even hear them. Especially now in the autumn with more chilly headwinds to contend with, the alerts this thing provides are invaluable. Riding around northern NJ on busy suburban and country roads, I really can't say enough good things.

Varia Radar Tailight

I've used it several times
True to size

My son has been using a Garmin Varia radar tailight for 2 years, and now that I'm doing more riding on streets & country roads with my local cycling club I want that extra level of safety. It works just as expected and is very reliable indicating the speed and closing distance of an approaching car. Setup was easy with my Garmin 830.

Wouldn’t ride without it

I've used it once or twice and have initial impressions

Went for my first ride with this amazing piece of technology. Works exactly as indicated. Easy to set up and use. Paired with my Garmin Edge 520. Display is great. Instructions in box are a little understated, but there are some very good you tube videos available. Haven’t tried it in a paceline, but I sure felt safer out on my own.
