Lezyne Ai Alert
Introducing the future of bike light technology: AI Alert. Lezyne combines artificial intelligence with advanced ALERT rear lights to produce the most precise cycling brake light on the market. This light automatically detects braking events, and intelligently changes its output mode to Active Alert: a fast, flashing 150-lumen "brake light" mode. It signals slowing down, effectively communicating your actions to motorists and other cyclists, which increases your visibility and safety.

IPX7 waterproofing
Submersion tolerance: this light can be submerged for up to 30 minutes, up to a depth of 1 meter. Do make sure you close the charging port well! Heading for a bike ride when rain has been predicted? No problem! An IPX7 rating indicates your light can handle a heavy rain shower and will get you home safe, even when the weather turns bad.
