    Customers are satisfied with the brightness of the vehicle accent light. They mention that it has a strong light source, the strobe light is very visible, and it increases their confidence while riding in the bike lane. The rear light also works well and it flashes a bright red light toward vehicles coming from behind to alert them. The beep was louder but the flashing LEDs work good and it saves battery and minimizes the annoyance to other riders in a bunch.

    "...is also a fairly slow pulse that both saves battery and minimizes the annoyance to other riders in a bunch...." Read more

    Check your mounting situation first
    I have a small saddle bag, and I also have a bracket for attaching a pull-behind third wheel for my daughter on my seat post. This made the regular mount for the RTL510 impossible to use. The limited height on my seat may partially be due to my cyclocross bike's geometry. I didn't want to dump the bike bag because that's where I keep my multitool and CO2 cartridges for flats. (that's all that fits). I already have a bag in front for my phone, wallets, etc. so I couldn't just dump the useful stuff out of the bag...So I went on a hunt for a suitable mount. There's a couple pre-made mounts out there that can attach to the saddle or extend out from the seat post more, but they were all either really expensive, no longer made, or out of stock for months. I figured out that I could get a GoPro saddle mount, a 90 deg extension, and the Garmin 1/4 turn to tension mount adapter to mount it in behind the saddle bag. All the parts were available on Amazon, but I ordered the Garmin adapter direct from Garmin (it was cheaper). The 90 deg turn on the extension was essential because the RTL510's mount is rotated. See the picture for the final result.I'm using the RTL510 with my Edge 530. I wasn't sure what to expect, but the radar feature is awesome. You get plenty of notice when a car is approaching. It also notifies you of upcoming bikes when you're riding on the trail, but it sometimes doesn't alert of those until the rider is very close. I've used it a few times at night now, and the brightness seems like more than enough. It's definitely brighter than my old Blackburn light (don't know the model). I had my wife watch the pattern as I was riding, and it's cool that the pulsing and flashing changes as you slow down and stop, but honestly are drivers really going to know what that means?Anyway, I'm highly impressed with this light even though I had to come up with a special mount for it. I can't wait to get the headlight next!

    5.0 out of 5 stars Works great, looks clean, good implementation with Wahoo Bolt
    Reviewed in the United States on December 11, 2019
    I bought this for my primary road bike after Wahoo added integration to their head units. After a few hundred miles of road use I am very impressed by its performance and the integration.

    - Picks up cars about 4-5 times farther back than I can hear them
    - No issues found so far with false positives or false negatives
    - Will detect multiple vehicles simultaneously
    - Only picks up vehicles that are moving in your direction and faster than you. This will include other cyclists if a fast pack is overtaking for example but not others right on your wheel. Similarly, if a car comes up behind you then slows down to match your speed they will fall off the radar until they move to overtake. This is by design and I think works well but make sure you are aware of the functionality.
    - The audio queue can be turned on or off. I currently set it to off (still have blinky lights at top and graph along left side) as I am more interested in cars behind me when I am going to make a maneuver (move left in the lane for a turn or roll off the front of a paceline). I don't personally need notified of every car passing me as I would almost certainly hold my line in the road anyway.
    - Blinky light mode has ~16 hours of battery (tested by rundown on my desk) and ~7 hours solid. It seems plenty bright to me in all settings. The flash mode by default is also a fairly slow pulse that both saves battery and minimizes the annoyance to other riders in a bunch. When a car is detected the light flashes faster. Good design. Using it on blinky I can charge it the same time I charge my head unit as both are ~16 hours.
    - Light looks clean on the bike and comes with bands for round or aero posts. I was able to mount it at the top of the seattube below the seatpost clamp and it looks almost integrated that way. Quarter turn mount has proven secure.
    - Wahoo does not have the lighting control so you will need to turn this on/off manually
