We welcome you to a new era of commuter safety
I bought the 'lite' version of the lumos helmet because I couldn't justify the additional pricing for directionals/brake lights. I have been ecstatic about the helmet, visibility to drivers is now at cycle level (my existing lights) and above - due to the helmet. I feel more confident riding and being seen by car drivers. Charge lasts >3hrs, so I have to plug it back in every three+ days (I ride ~1hr per day), and since I have yet to take it on that long of a single ride, it is not a problem. Other riders ask where I got the helmet.
Seems to work fine - during the daytime the lights on the front could be a little brighter (during dark they are fine) Helmet fit and finish is good. Comfort is good
