Whether you're commuting when daylight is at a premium, or you're pedaling out pre-dawn base miles, you probably blowing through eight packs of batteries like thorns on tires. So, to save you some cash, without compromising on safety, NiteRider create the new Solas 2 Watt USB Tail Light.

The Solas provides four modes (two flashing and two steady) and a "Group Ride Mode" for those who need to feel visible in the pack. Rechargeable via USB connection, the Solas will last around 36 hours on low-steady mode, 4.5 hours on high-steady, 18 hours with a single flash, and 7 hours with a double flash. The bright two watt bulb is visible for blocks, increasing your visibility to motorists when office meetings run late.

The NiteRider Solas 2 Watt USB Tail Light comes with a bike mount and a USB charger.

Great for the dawn patrol

  • Familiarity: I've put it through the wringer

We've got a group that rides t/th at 0530. I've got this mounted down low, on the seat stay. Its got a mount that lets it mount on a tube which is not just seat tube diameter - and that's great, as I've got another light there. Anyway, this thing is bright. Super bright. Run it in steady mode, rather than blinky, so it doesn't make the guys behind me go nuts on the group ride.

The mount holds on on the road and on the dirt - admittedly, I'm more cautious when my road bike goes on the dirt, but it does, and this light stays in its mount.

I like that it tells if it needs a charge by lighting up blue or red when you turn it off. Pay attention and you'll know when to plug in the USB cable and charge it up.

Negative: The USB cable has one standard side (usb) and one light-specific side, so I cannot use a standard cable to charge; always the one that came with the light.

Bright and Safe.

- It is small and compact.
-No external wires.
- East to swap between bikes.
- It’s extremely bright and provides amble visibility to cars as they pass. It charges easily.

Cons: No complaints.

Excellent tail light. It's very bright and lasts on my three to five hour rides. What more can you ask for.

NiteRider Solas Tail Light

  • Familiarity: I've used it several times

Turned it on and immediately blinded myself lol. This thing is BRIGHT. This might be pricey for a tail light, but I got mine on sale for $30 dollars, including shipping, and that's a steal for this. Compared to the Bontrager Flare 3, that costs more, the Solas wipes the floor with the Flare 3 in every aspect. Four modes, water resistant, rechargable, VERY BRIGHT... what more could you want? Definitely recommend to anyone that rides any type of bike. This light is great.

Super Bright

  • Familiarity: I've used it several times

Super bright light. 2 flashing modes and 2 solid modes make it easy to be seen by vehicles and other riders alike. I go with one of the flashing modes on the road by myself, dim solid mode for group riding, and bright solid for night time MTB woods fun. It pairs well with the Niterider Headlights I have (I have a 400 and 700 lumen model) to make for a really highly visible package. Easy to charge with USB, and for $30 (when it's on sale), it's a STEAL.

This light is super bright, which is what you need.
It comes with a short USB cable for charging and a slightly flimsy bracket to attach it to a seat stem. I got it for $30, so happy with that.
UPDATE a week later and the flimsy bracket broke

Great Night Rider Rear Light

    I brought this light for $44 and thought it was a little expensive for a small rear light. But, it is worth every penny. I have been riding with it for about a week. My buddy told me this morning that it is a little bit annoying when riding behind me, but he said he would take that any day to be safer. The light can be seen very good. Much brighter than my AAA battery model. Holds a charge for over 30 hours of riding.
