r/bikelights

I already have a good full-size headlight for riding at night, but I'd like to find a smaller, lighter option to use as a daytime running light, i.e. a white front flasher. Ideally it'd be USB-C rechargeable, and could mount to a 1/4-20 or Garmin or similar fitting, so I could just mount it under my bike computer mount.

Everything I've seen is trying to be a true headlamp, with a sharp cutoff and long throw, and a large battery capable of sustaining hours of steady light. That's great, but for daytime rides, it's overkill for me. Are there any good daytime running lights with a wide spread, smaller battery, and attention-getting strobing?

What are the best, cheap bike lights you can buy in bulk?

I'm looking to buy as many lights as I can to give away to any riders who need them. Ideally, they'd be water-resistant and rechargable.

Some riders think so. I’ve seen complaints about multi-click sequences just to change modes, hidden long-press functions, and app menus that feel heavier than the ride itself.

One rider said his old light had one button and zero confusion—on, off, done. Now he needs a cheat sheet for brightness levels and flashing patterns.

Others don’t mind the complexity, as long as it stays predictable once learned.

Feels like the real question is whether “smart controls” actually make night riding easier, or just more technical.

What’s your experience—simple or too many steps?
