At first I was hesitant to get a battery powered headlight and taillight, but after I installed it (with ease), I LOVED IT!! The LED headlight is very bright and the LED taillight is virtually impossible to miss (I think it is as prominent as some motorcycle taillights). The ability to flash each light and the taillight also having orange lights on the side makes it even more visible. Mounting the lights on my bike only took 15 minutes and only the taillight needed for me to use a screwdriver (to tighten and tweak the angle). The LEDs are really great and so far after using it for over 4 hours, I see no fade in the light power. The headlight has four LEDs with 3 modes (4 steady, 2 blink 2 steady, and 4 blinking (which looks like a strobe light)) and the rear also has 3 modes (steady, steady blinking, and random blinking). Be aware that you will need a jewelers screwdriver to open the rear taillight to install the batteries. Each of the lights detaches from the bike mounts and allow you to use them when camping or to clip on the taillight to your bookbag or clothing for visibility when walking along a highway or where cars are present, and the headlight can be used as a nice flashlight. The only thing I have to say is that you still need to look out for cab drivers in the Big Apple, since they can't stand that your lights are brighter than theirs and seem drawn to bikers while driving. Get this light, you won't regret it, I sure didn't. :-) 5 stars

I recently rode my mountain bike in the Houston Moonlight Ramble at the end of Oct, which is a 20-mile ride at night (2-4am) in downtown Houston. About a month before the ride I was looking for a good light set that wouldn't break the bank as I do not do a lot of night riding. I could tell the cheapie ones at Target/Walmart just were not going to make me happy.

Was very pleased to come across this Blackburn combo here at Amazon. It was just a few dollars more than the Walmart versions that surely would not have been as bright. Plus the styling of these lights look SOOOO much better.

The optional modes are nice. For night riding I prefer the front solid w/flashing sides. The pure flashing mode is like a strobe but is good for dusk type situations where there is adequate light for riding but lots of shadows, so you are not really using the headlight to see but to be seen.

The tail light is all about being seen. As others have said, it is SUPER BRIGHT. But that's a good thing. You can have constant on, or the more attention getting flashing or chase modes. I used chase mode (goes up and down so a light is always lit) as flashing gets lost for half a second so you can't tell change of direction immediately like you can with constant on.

I would highly recommend this light combo set for casual night riding and/or commuting with mostly city lights. If you do a lot of night riding in dark places, I would suggest a stronger headlight and get the Mars 3.0 tail light by itself (great tail light). 5 stars

As others have mentioned, as lights, these are bright, visible and wonderful safety aids for bicyclists. I use mine not only in darkness, but especially in the early morning and evening twilight hours. They are quite visible and send a clear message to cars. The front light is well executed and has gotten through many rainstorms without a hitch, though it is a bit loose on my 22 mm handlebars, so I will need to add a shim. The problem lies with the rear light. As a light, it's great, but the clip is very cheap. I have now lost two of these to the clip breaking. it is that kind of plastic where, if you try to bend it, it will snap quite quickly. Unfortunately, it is also a very tight clip, so, when putting it on the leather or cloth strap for a light on the back of my panier rack/bag or tool bag, it's very hard to get it through and eventually snaps, especially if you tend to remove it for any reason. Sadly, this is the trend with Blackburn. I am now looking for a new cyclometer, as theirs turned out to have a bad button, would lock up after every ride requiring a reset and reprogramming, and eventually died completely from a mild rainstorm. Great designs, poor execution. 3 stars

I purchased this set about 6 months ago at a bargain price (less than $17). After six months' use, I am still very pleased with the durability of the light, the long-lasting battery, and the ease of installation. (I am not mechanically inclined, and even I could do this myself).

Highly visible, three settings (steady light and two blinking light options). These make me feel much safer when I'm biking at night.

Highly recommended. Exceptional value for the price. 5 stars

Truly a quality light, constructed well, and bright enough for street riding. However, the mount for the Quadrant tends to shift easily even when hitting a small bump in the road (even with the mount fully tightened). I called Blackburn regarding this issue, but they don't have a fix for this, not even a small spacer. What good is a quality light without a sturdy mount? And what good is a lifetime warranty if they are unable to even provide a minimum level of support? 3 stars
