AKALE Rechargeable Bike Light Set, LED Bicycle Lights Front and Rear, 4 Light Mode Options, Bike Headlight, IPX4 Waterproof, Easy to Install for Kids Men Women Road （2 Pack Black）

Product is great but would recommend two improvements: limit to 2 modes and support USB C charging. Otherwise no compliants.

So I had originally bought some battery powered rinky dink "universal" lights that were total garbage BEFORE upgrading to these lights. Now I've actually mounted all 4 of these lights on my road bike. For me, it's about visibility and boy let me tell you, I look like a friggin spaceship rollin down the trail at 530am to do my hill repeats. Multiple blinking modes, (and why they included 4 charging cords I really can't say) but they are formidable; I now no longer worry about if folks can see me, that's a no brainer. If the lights don't last the entirety of my next 4 hour ride in 2 weeks, I'll come back and update this review to reflect that. But it does give me peace of mind that I have a higher liklihood of being seen and coming back to my family.

These bike lights are economical and very bright. But, I bought them for a completely different application. As an RV'er, I wanted to add nighttime roadside emergency lighting as an added conspicuous alert to my collapsible reflector traffic cones I carry in the vehicle. The handy belt clip on these make it easy to attach to the cones, or me too! Would work on the DOT Warning Triangles also. I tested the white and red lights in direct sunlight, and I feel they are bright enough to help catch an approaching driver's eye (especially the white ones). After a first recharge, I did a battery life test and they ran a solid 8+ hours, although noticeably dim near the end. That's good enough for an all night roadside emergency.I should note that I looked of course at most all the various styles of LED road flares first. Wanted the brightest light possible. The popular puck styles project light in all directions when traffic is approaching mostly from the rear. It seemed the overall brightness was reduced because only one LED projects in any direction. So I decided to try the bike lights which projects 4 BRIGHT LEDs in one direction. Secondly, anything that sits low to the ground might not be seen right away depending on the road surface topography. I place these lights about 17" high on top of the traffic cones aimed at approaching traffic to provide better visibility.

These are much better than I thought they would be! Actually very bright. I use them to keep myself visible to motorist, so I am in flash mode so far. I charged the two lights over a week ago, ride 20 miles every other day, so they flash for about 2 hours each trip and they are still working! Have not had to recharge yet! Mount is simple and small. Nice non-cumbersome option for my bike!

I bought TWO (1 set) of this brand and feel comfortable enough that I decide to buy this one (2 set of lights). So I now own 4 sets of these for my (4) 20" folding bikes. It is easy to set up and there's really nothing else I can say more about this product. The product came with charge, and I have not used up my battery charged yet. So far it works great and I notice it's very bright. I feel comfortable enough that cars and bikers will notice/ see me. I will update more once I need to charge the battery! Buy with confident!!
