The radar system is one aspect of Garmin's new Varia range. It's also marketing a set of smart lights that adapt to your speed and weather conditions. If paired with a compatible Edge GPS system, the Varia headlight will project its beam further ahead at faster speeds, and closer at lower speeds. The matching tail light uses the same data to increase its intensity when a cyclist is slowing down in order to warn approaching traffic, and both can automatically adjust their brightness via the GPS unit's ambient light sensor.

All the Varia products go on sale this fall. The complete radar system will cost $199.99 if you just need the sensor, or $299.99 for a bundle including the handlebar display. The smart bike lights will set you back $199.99 for the headlight, $69.99 for the tail light, or $299.99 for a bundle including a remote.

Bonus points go to Garmin for creating such a terrifying advert. "The threat is real," people.
