Lezyne just unveiled the newest piece of their Radar React System, and its called the Radar Pro 300. Essentially a smaller and lighter version of the recently released Radar Drive Rear, the Radar Pro 300 adds a feature and still comes in at the same price. Adding to their collection of in-house-developed radar tech, the Radar Pro 300 also includes an automatic brake light feature. The light will sense you slowing down and will automatically increase the lumen output either in solid or flashing modes, for an additional layer of rider safety. Otherwise, the light is very similar to the Radar Drive Rear with a 300-lumen daytime flash mode, 270 visibility, and radar that claims to detect vehicles up to 150 meters away. It can also be paired with the React Drive Front Light, which provides visual radar notifications without the need for a head unit. The two can be purchased separately or as a pair. In addition to connecting to any cycling computer that supports radar light notifications with Bluetooth or ANT+, the Radar Pro 300 can also be connected to the Radar Ally smartphone app for real-time visual and audio alerts, and the app allows you to customize the output modes and alerts of the light itself. A 2000 mAh battery delivers better performance than the Radar Drive Rear, now offering a maximum 24-hour runtime (on radar mode only; on Flash mode youll get up to 20h). And thanks to the EU Battery Regulation, the battery has a replaceable design should you wear it out in the distant future. While slimmer and more compact than the Radar Drive Rear, the Radar Pro 300 is still IPX7 waterproof with a USB-C charging port. Claimed weight for the light is just 94g, with the light plus mount starting at 108.2g and up depending on the post and adapter. The new light also has a new mount with a quarter-turn mounting interface to quickly install and remove it from the bike. The mount works for any round seatpost and includes two adapters for aero and D-shaped posts.

Thats right, but soon the Radar Drive Rear will be given a new lower price of $149.99, which will actually make it a bit of a choice. Either way, Lezyne now has two options for rear radar lights, which are priced extremely competitively and have great features.
