Lezyne Strip Pro Ai Alert 400+ Rear Light Info
The Lezyne Strip Pro Ai Alert 400+ Rear Light does something most rear lights don't: it knows when you're slowing down. Built-in Ai Alert brake-sensing technology detects deceleration and automatically triggers a rapid 150-lumen Active Alert flash — signalling your braking to riders and drivers behind you without any input from you.
Ten super-bright LEDs push up to 400 lumens in Day Flash mode, with 270-degree Wide Angle Optics ensuring coverage well beyond the rider directly behind you. When you need to stretch battery life, Femto mode extends runtime to 80 hours. The co-molded construction is IPX7 waterproof-rated, a versatile silicone strap fits both aero and round seatposts, and a 1900mAh internal battery recharges via USB-C — seven output modes give you control over the balance between brightness and endurance.
