Is your light bright enough for road riding safely in unlit areas up to around 25mph? If so, which light is it? I bought a Light & Motion Solo Logic a couple years ago and while it's a good light I start wishing for more illumination at around 15mph. It puts out 390 lumens on high. I would consider anything less than that pretty much just a safety light or only for use in lit areas or at low speeds.

Thanks.
