FAQs
How does it work?
The LED bar is a bright red rear light. The laser projects a red spider pattern onto the road on both sides of your rear wheel, marking out your space so drivers give you room.
Is a laser bike light legal?
Bike lighting rules differ by state and country. Most places require a red rear light at night, which the LED bar covers; some have rules on flashing lights or projected light. Check and follow your local laws before riding. LazrVex is not responsible for fines or penalties resulting from how the light is used.
Will it fit my bike?
The rubber strap fits most round seat posts and handlebars, on road, gravel, mountain, hybrid and city bikes.
What's in the box?
The LazrVex light, the rubber strap mount and a USB-C charging cable.
Can I see the laser during the day?
The laser lines show best at dusk and at night. In daylight, use the LED bar in a flashing mode.
Is the laser safe for eyes?
The laser points down at the road, not at people. Never look into the laser opening or aim it at anyone's eyes.
How do I charge it?
Plug the included USB-C cable into the light and any USB port or phone charger.
Can I ride in the rain?
Yes. LazrVex is rated IPX5, sealed against rain and spray. Don't submerge it.
