NiteRider Solas 100 Lumens USB Rechargeable Bike Tail Light Powerful Daylight Visible Bicycle LED Rear Light Easy to Install Road Mountain City Commuting Adventure Cycling Safety Flash

I've used the Solas 100 for many years and am very happy with it. It's rechargeable, bright, and has a long battery life. In my experience, the battery in blinking mode lasts longer than it claims, and I feel confident it will last me on the majority of my rides without recharging up until I see the low battery warning.With other lights, I've found battery drain and run out before even getting the low battery warning due to poor battery life. I've also tried the Solas 250, but found that the battery life was disappointing - I suspect the two products use the same battery. The 100 is bright enough and I'd rather have the longer battery life and peace of mind that it won't drain completely mid-ride.Also - a note on durability - I've seen folks comment on the charging point being a point of failure. In my experience, that has been a point of failure in the past. My first lasted only a year before failing, but that was because I did not firmly secure the rubber seal leading to grit getting into the port. My last light lasted 3-4 years - also failing from charging port (but acceptable given how long it lasted), but again due to user error - I got water up the charging point due to hosing down my bike without fully securing the seal.I think as long as you make sure the rubber seal is firmly secured after charging, or before a hose down, it'll last just fine!it's bright, light, and rechargeable. As long as you make sure the rubber seal is firmly protecting the charging port, it'll also last a long time.

In my experience, rear lights are more important than headlights when cycling on public roads before dawn. The battery lasts for about an hour which is plenty of time for my morning, pre-dawn rides. This is my 3rd NiteRider Solas 100 light in the past 10+ years. My only gripe is the USB female connector on the light shorts out and wears down over time and after many charges. This is replacing a dead Solas 100 with a bad USB connector. Still, it lasted many years.... good product. The light is more than bright enough to be seen over 100 yards for passing vehicles. Highly recommended.

Finicky light settings, great light beyond that

Love the light, but I've had to replace the mount several times (although I've gotten replacements with warranty).

I have had NiteRider products for years. They have excellent quality and last for years. After a few years when the battery life isn't as good as it once was I replace them with the same product. I have bought the Sloas 100 for quite a few years now (very bright) and when I used to ride to work I used their headlight which worked great for riding to work in the dark! I purchase two tail lights at a time because my wife and I both use them when we ride. The battery life wasn't quite as good as it was on the last one so I contacted their service department. It was so great that a real person answered the phone and they were easy to understand (no thick accent)! He was great at answering my questions and helped me with my problem beyond my expectation! I highly recommend the NiteRider lights and love their customer service!

Really like this light. EVERY vehicle that has passed me on the road since I installed this has moved completely over into the adjacent lane, never trying to share a lane with me. I lost one light due to user error- failed to completely seat the light on the mount and it vibrated off. Now, after 7 months and charging after most rides, the charging port has failed on the replacement. The interior contacts have folded and cannot make contact. The good news is that it took about 7 or 8 hours of daytime strobing before the light failed after the last successful charging. Now, however charging is not possible. I am currently away from home and don't have much in the way of tools. I may be able to jury rig a replacement charging contact when I get home. My other light (on the wife's trike) has been getting harder to charge. must carefully insert the plug part way in, and set it down on the table just right to enable a charge. I have done a bit of filing and have inserted a magnetic connector which enables charging. To do that I had to rip out the rubber weather seal. After I return home I will seal the opening with silicone which will still allow me to charge and keep the weather out. It looks like they really went out of their way to use the cheapest possible charging port available. I like the way it works, I like the brightness and the excellent battery life, but if I can't recharge it, it is worthless.

This tail light is great! Living in a city, I need lights that are reliable, bright, and easy to remove.I really appreciate how easy it is to pop this on and off the bike. I can't leave anything on my bike because if it isn't bolted down, it is going to be stolen.I love the different setting options so depending on if I will be in the street or on a bike path, I can adjust to save battery life or to be more visible when I'm on the road.

This light is bright, is easy to recharge, and worked well for just over 2 years. Then it quit. Refused to recharge. I would give it a higher rating if it had lasted longer.
