Garmin varia™ RTL 500 ANT+ enabled cycling tail light with radar

Features

Overview: Garmin Varia Rearview Radar is the world's first cycling radar that warns you of vehicles approaching from behind. Because getting hit from behind is the leading cause (40%) of cycling fatalities in the U.S. (according to a study by the League of American Bicyclists), Varia radar helps protect you by giving you an extra set of eyes watching behind you. This package includes the RTL 500 Rear Tail Light radar unit.

Varia Smart Bike Lights: The Varia line of cycling awareness products includes smart tail lights, smart head lights, and dedicated display units. This RTL 500 rear tail light can detect vehicles approaching behind your bike, and wirelessly display the relative speed of approach and threat level on compatible Garmin Edge cycling computers. The RTL 500 also brightens and flashes to notify the approaching vehicle of your presence.

RTL 500: The RTL 500 rear tail light mounts high on the seat post on your bicycle. The RTL 500 uses low power radar to detect up to 8 vehicles approaching from the rear, and alert you through a dedicated Varia Radar Display Unit (RDU) or a compatible Garmin Edge bike computer (such as the Edge 1000 or Edge 520). The radar detects approaching vehicles up to 153 yards (140 meters) away, at speeds between 6 and 99 mph. The radar beam width is 40°, to provide coverage for typical bends in the road. The tail light features eight red LEDs. The four middle LEDs flash at all times. When a vehicle is detected, additional LEDs progressively turn on and the flashing frequency intensifies to alert the approaching vehicle of a cyclist ahead. You can also switch the LEDs to solid mode, if desired. The RTL 500 uses 2.4GHz ANT+ technology and wirelessly links to the RDU or Edge unit. Dimensions of the RTL 500 are: 2.852"W x 1.71"H x 0.913"D. It weighs 2.2 ounces.

Garmin Edge Compatibility: The RTL 500 is compatible with the Garmin Edge 1000 and Edge 520. These Edge units will indicate the detection of a vehicle approaching from behind through a series of LEDs along the right edge of the display. The single Threat Level LED changes color based on the potential level of the threat: green (no vehicle detected), amber (vehicle approaching), or red (vehicle approaching at a high rate of speed). A column of LEDs indicate the position of the approaching vehicle. The lit LEDs move up the column as the vehicles get closer to your bike.

Rechargeable Battery: The Varia RTL 500 is powered by a built-in rechargeable Lithium-ion battery. The battery life is approximately 5 hours in constant illumination mode and up to 8 hours in flash mode. The battery charges in approximately 2 hours via USB, using the included Micro USB cable.

Mounting: The RTL 500 is equipped with two "quarter-turn" mounts, a universal mount and a seat post mount. These are the same type of mounts used by many of the Garmin Edge bicycle computers, and allow you to easily attach or remove the tail light.

Water Rating: The RTL 500 has an IPX7 water rating, making it suitable for use in rain or snow. It can withstand incidental exposure to water, but is not suitable for immersion.
