Side Lights for Cyclists. Amber, Bright, Rechargeable and Waterproof

Fantastic!Due to my work hours the majority of my riding time falls at or after dusk. I have more than enough front and rear lighting, as well as reflective gear, but I often encounter distracted drivers at two and four-way stops. The only way that I can get their attention has been to turn my handlebars toward them and blind them with my headlights (when I am stopped) or to hope they see me (when I am moving through the intersection)... until now.On to the review:I ordered four lights for the family and was pleasantly surprised when they arrived on the earliest day listed in the range of dates for delivery. They had, in fact, shipped the day after I ordered them. Something I find refreshing since so many companies take what seems to be an unnecessarily long time to process orders. They all arrived in great shape too.My first impression is that they are well thought out and well built. For details on the operation I suggest you check out the company website but suffice it to say that they are easy to mount and work as advertised. I have not had a lot of time to ride with them so I can't yet report on their long term durability but I am quite certain that they will do very well.I wanted to see how a driver might react to them so I had my daughter ride through a nearby intersection in order to determine what a driver would experience. I was unable to distinguish her headlights from the ambient light as she passed through the intersection but the fact that she was there was made abundantly clear by the very bright amber light from the Brightside light. Success! As she continued away from me I could see the taillights clearly but I was also able to see the Brightside light as it reflected from cars and houses on both sides of the street. She then came back and turned toward me. While her presence was clear due to the headlights the Brightside lights were what caught my eye. They were the first lights that could be seen well as she approached and began her turn and were visible through the entire turn.Bottom line: The Brightside lights provided the most consistently visible warning that there was 'something' that needed attention. They were visible in one form or another whether coming toward me, moving away from me or crossing perpendicular to my line of sight.I plan to add to this review once I have had a few months with them but don't wait for that. My advice is to give the Brightside light a try If you ride at dusk or during the night and have to ride in areas with cars.David C. Thompson

"Brightside" Bike Side Light(+) Nice small size.(+) Mounts securely. (I push the light to one side of its mounting bracket and use two velcro straps to "dummy cord" it to the frame as precaution against it coming detached inadvertently, but it has not fallen from its mount riding over rough terrain yet)(+) Light mounts perpendicular to the bike frame, to shoot amber light beams out from each side of the bike for lateral / side visibility. (1x Steady light mode or 2x flashing modes [1x simultaneous and 1x alternating]).(+) Large lighted soft push button on top for easy operation.(-) Charging port, on bottom side of the light body, is partially covered when light is centered in the mount (so to charge it the light must either be taken out of the mount each time (risking breaking the thin hard plastic mount) or one must keep the light pushed to one side of the mount (which I do).(-) Rode for two weeks (10+ rides of over 1 hour each) before charging. Took several hours plugged in (to the provided micro USB cable) to get it to "go green" again with a full charge.

Bought this light to increase my visibility at intersections. Installation was easy, opted to use both rubber straps to secure the light to my bike. The micro usb port is odd, it requires a longer tip to charge since the port is recessed, they include a cable for this. The rubber cover over the usb port is flimsy and could easily break off. Wish they would release a USB C version.Official specs from their own manual (for some reason this info is not on amazon or their own website):Battery: Li-ion 3.7v 650mahCharge port: Micro USB (requires an extra long micro usb tip since the port is recessed in the housing)Cree LED - Amber - 1 LED per sideLight Modes:Double Flash - 15 lumens per LED - upto to 15h run timeFast Flash - 30 lumens per LED - upto 23h runtimeConstant Both - 15 lumens per LED - upto 2.5h runtimeAlternating Flash - 15 lumens per LED - upto 36hr runtime

UPDATE of 11/29/22 I contacted the company and the OWNER answered my email. He welcomed my comments about charger cover and failure to charge (documented below). Sent me a brand new light, which I received today. Changed my rating to five stars because of the personal and kind attention by owner. Thanks, Aidan.ORIGINAL COMMENTS FOLLOW Like: Amber light is visible, although not brightly, it the daytime; gets attention if you're looking. Very bright at dusk or night. Very long battery life (a week's worth of rides, maybe 15 hours++). Solid construction. Can be charged (as from a power-pack) and operated at the same time, but long battery life probably makes this unnecessary.Dislike: The charge port cover failed (separated) the first time it was opened, thus negating any water resistance. The cover has no retention stub/knob at the attachment end that fits into the light body. I'm not ham-handed; the thing just fell out of its own accord, with no way to repair.UPDATE of 9/12/22 The light will not recharge now. As another reviewer has stated, you have to hold the USB terminal in place in order for the light to charge. Not gonna do that. Unsatisfactory.Because of these two failures (charge port cover and now the charge issue) I've changed my rating to one star from four. I leave one star because it did perform well for 9 months since I bought it.
