If you’re just riding under streetlight or during daylight, and want a ‘be-seen’ light, then the starting point is the Bontrager Glo or Lezyne Femto Drive. They have solid and flash modes, are easy to take on and off with rubber straps, are small enough to fit in a pocket, and are powered by watch batteries.
Still in the ‘be-seen’ category, but slightly brighter, are the battery powered Bontrager Ion 35 and Ion 120, or the USB rechargeable Lezyne Zecto Drive.
Staying on the road, if you need to see the ground in front of you the 400 lumen Lezyne Micro Drive will suffice for slower riding on well-made roads, with the 600 lumen Macro Drive providing a better experience if you’re moving quickly.
Moving off-road, go for the 1200 lumen Super Drive, or 1500 lumen Deca Drive.
Unconditional Bontrager Guarantee - all Bontrager lights come with a 30-day trial period, if you don’t like it, return it for a no-quibble refund.
