Why We Like The Seca 1800 eBike Light

Time-tested since 1989, Light & Motion is one brand we're into because of their name in the industry of portable lighting and the versatility of their products. This brand is passionate about lighting for photography, cinematography, and scuba diving, but right now we're zeroed in on their Seca 1800 eBike Light.

Bright and compact, the Seca 1800 eBike Light brightens our way when our ride gets away from us and we're caught in the dark. According to Light & Motion, it's the most powerful light engineered for e-Bike integration in the world. We're using it for gravel paths and country roads on dark, cloudy nights, where a good bike light is a necessity.

Doesn?t turn off

I've used it once or twice and have initial impressions

It doesn?t turn off. I called L&M and they told me it is designed to stay on all the time. I asked them what the power button was for...they replied it?s not a power button. ...Well, it looks like a power button to me it has the power button 1/0 icon on it. Item returned.
