## Description

See and be seen with Garmin Varia RTL515 rearview radar with tail light. It pairs with your Edge bike computer, other Garmin device or compatible smartphone to alert you of vehicles approaching from behind up to 140 metres away. When used with your compatible smartphone, the Varia app helps increase your awareness with vibration alerts and more. With daylight visibility up to 1 mile, motorists will be able to see you from a distance. The radar’s compact vertical design allows for device mounting on most road-use bicycles. And peloton mode provides a low-intensity flash that is kind to other riders’ eyes when riding in a group.

Review: Great light and the radar is a helpful additional safety feature - I cycle a lot, all year, in all weathers. Primarily road cycling. This rear light and radar is expensive. But. Its a good light with good range and handles spray and heavy rain well..no issues with battery life and I'm told that it's pretty bright. It links to my Garmin Edge 530 easily for the radar and for any necessary software updates. Comes with variety of attachments to suit your seat post. The radar, which is the main reason for my purchase activates pretty accurately and in my view is a great safety addition especially at night or bad weather. Its radar function notifies vehicle proximity on my Garmin Edge 530 by flashing orange and reporting the cars location as large white dots approaching you on the right of the screen. The first beep and flash to indicate a car is approaching from the rear occur at about 60-75 meters away. It also indicates how many cars there are each with their own dot closing in on you. In my view it's pretty accurate most of the time. The Edge display functionality is not affected when notifying you. Display screen borders change colour when there is a car directly behind you roughly 2 to 3 meters away. It does not replace physically checking before making a move or turn. But it helps as an additional safety tool to improve your road awareness and a prompt to check before moving. Could do with a small elastic lanyard to larks-foot around the seat post incase it's mountings we're to loosening come off, in the same way as the Edge 530 has. Would I recommend....Yes. Strongly. I don't cycle without it day or night.But its not cheap!
Review: Superb aid to cycling safety - To be honest, this device actually works better than i'd expected. It gives a clear audible and visible indication of approaching vehicles (cars/bikes and lorries). The sides of the screen on the Garmin head unit light up amber or red depending upon the approaching speed. Once a vehicle (or multiples, it shows a dot on the right hand side for each vehicle) have passed, the screen sides go green for a few seconds to show it's clear. This unit has allowed me to know that vehicles are approaching before i even hear them. Of course you can't tell how close someone is passing but it's a massive help overall. It's actually useful to just know when there is nothing behind to, without having to keep looking back. It hooks up to the head unit with very little effort and just works. Brilliant piece of tech !!!!

## Questions & Answers

**Q: Does the light frequency/intensity change as cars are approaching - to alert the driver of the cyclist?**
A: As the light is on the seat post facing on coming traffic it flashes. A driver would not necessarily know about the sensor, so it does not make a difference. Your bike computer will emit a beep as a vehicle gets closer, similar to parking sensors on a car. It also shows a car symbol on the bike computer and the beep with be faster if a vehicle is coming up behind fast. It's a fantastic bit of kit. If you are cycling with another person the beep is loud enough so they too are alerted to a vehicle or motor bike coming up behind.

**Q: Anyone use this with a garmin 520 plus if so how do you find it works ?**
A: Although i haven't a 520 plus,  I've used the varia with a 25 and a 530 with no issues - clear display and audible beeps (that you can turn off in settings) when a vehicle is approaching. I don't leave the house without mine as it gives me so much more awareness of traffic approaching from behind, usually a few moments before you hear anything.

**Q: What’s the difference to the more expensive £299 one?**
A: I believe £299 includes the Garmin bike computer too as a package. If you have a bike computer already or use your mobile phone the light sensor can be linked to various ones. Mine was linked to a wahoo bike computer I already had so didn't need to spend the extra.

**Q: Is this a rtl 510, which is a different product to the 515? that is what is printed on the back of the light, on the product picture.  thanks.**
A: The RTL515 has a light and radar, the RTR315 is just the Radar and the newer RCT715 is the camera, radar and light.
The RTL510 is the previous model of the RTL515.
I do not know when they changed the designation.

### ⭐⭐⭐⭐⭐ Excellent product for increasing personal safety on the road.
*by D***. on 21 November 2025*

This is an excellent product to increase your safety whilst out on the road. The device gives plenty of warning of approaching traffic and the display on my garmin computer shows the distance the vehicle is behind which is a great feature. Battery life is good and lasts a couple of rides for me which is about 7 hours approx.
