I bought 3 of these sets for 3 different bicycles and all were installed easily. All lights were in good condition. For my son’s bike which has the seat all the way down, we installed red blinky on the left back fork, the rotating feature made it easy to install to the side but flip out to face the back. Lights are working great 3 months later. Beamer 1 is great for visibility, it is not extremely bright, but we commute mostly in a well lit area and without heavy traffic - it will light a path dimly but you may prefer something brighter if commuting in darker, rainier, conditions with more traffic. For our purposes - commuting about 3 miles on bike route streets, these are an affordable option. Flash or solid features are simple but effective.

The rear light is great. Has a flashing or solid setting and can be seen very clearly, better than most other bike lights I see on the streets. It reflects as well, not like the new super small LED wristband type lights that quickly wrap on and if not placed well can only be seen from limited angles.It lets up a bit on the front light. No matter what I do, I cant get the light to stay mounted straight. I need to pay attention to make sure its not facing down on my knees where it likes to rotate too. Instead of helping you see you just look like a perv riding around the city with your crotch lit up.

Very good safety part to a bike... smart that they are packaged together. The flashing light on country roads is a wake-up for oncoming traffic.

not the best but very good for what i needed for, what do you want for the price.

does what it should do

First off, for deciding between different Planet Bike lights/light sets, I went to their website because they have this great simulator to show exactly how bright the lights are. I found that super useful.I just needed a simple and relatively cheap back and front light for short commutes at night around a busy university. The back light is perfect, fits onto the seat post very easily and securely and is really surprisingly bright. I always keep it blinking when I ride at night, because I feel like that attracts drivers' attention better and doesn't use as much batteries. Speaking of batteries, I've used both of these lights fairly frequently for the past 6 months and haven't had to replace any batteries yet.The front light is very sturdy. It's a little too heavy for my taste, and I would actually expect it to be brighter for how big it is. If you're actually in need of a light to ride in complete darkness, I would absolutely find something brighter than this. I don't think the range is very great. However, if you're riding on lit streets (like I do), this works just fine to alert drivers of your presence (which is really what I wanted). The front light is a little too complicated to set up, it has a quick release that I don't feel is really necessary, but once you get it on there it won't budge.Overall, a great light set for the price.

The review is a little mixed because I really like the tail light but don't care much for the headlight so I'll review them separately.Headlight:Pros: Well made, solid construction, easy to install, solid and blinking light options are good.Cons: The button is on top, so when i put it in my pocket while my bike is locked, sometimes it turns on by accident. It's also not very bright. I live in NYC. Thankfully most of my route is well lit, but some side streets or more residential neighborhoods have poor lighting on the street. It would be nice if it was bright enough for the streets that aren't well lit.Overall: Decent light if you just want to let cars and pedestrians you're there, but not necessary need to see what's in front of you.Tail light:Pros: well made, solid construction, clothing clip is firm, solid and blinking light options are good.Cons: Don't really have anyOverall: This is a great tail light. I leave it clipped to my backpack all the time. i don't remove it whether I'm biking or not. It's bright enough to let everyone know I'm there which is the most important thing about the light.Summary: i'd suggest buying the tail light by itself and investing in a better headlight.

QUICK SUMMARY: I like this product enough to equip all six of our family's bicycles with this combo unit. They're easy to attach to the handle bar (once you understand the mechanism), easy to remove, and do a good job helping others to see you. Don't expect to use this headlight to illuminate a dark road at night, though.There are six reasons why I like this set:1) LED lights are much more energy efficient than the old-fashioned, incandescent light bulbs I used to use growing up. Saves money on replacement batteries.2) The headlight beam, when focused correctly, is very bright and can be easily seen by an oncoming car from a faraway distance. Similarly, the red tail-light, when properly focused, can also be easily seen from an approaching vehicle.3) The physical size of both the headlight and tail-light are very compact, so they look nice on the bikes.4) They're weatherproof enough so if you're caught in the rain, both devices should keep working for you.5) They're easy to mount on the handlebar and seat post. I used one of the rubber inserts to ensure a tight fit on the handlebar. The headlight doesn't require a screwdriver to install; the tail-light does need a screwdriver.6) The headlight is easy to detach from the bike. I liked this feature when I was nighttime riding, and I wanted to stop and take a look at an armadillo along the road. So, it doubles as a handy flashlight, too. The tail-light is easily detached from the mounting bracket, too, but you'll probably do that only to replace the batteries.I have four caveats to share with you:1) The headlight isn't good enough to illuminate a dark road well enough that you can safely ride at night. You can do it, but the road will be dimly lit up. There's only one white LED in the headlight. It's fine if you're riding at night on a well-lit road and you just need a headlight so others can see you. If you need a headlight to really light up the road for you, look elsewhere.2) Both the headlight and tail-light need to be properly focused so an oncoming vehicle can actually see you. They need to point almost straight ahead so the beam can be highly visible to an oncoming or approaching vehicle. If not pointed correctly, the bright intensity of the LED lights won't help you become visible to others.3) Even when the lights are correctly focused, the bright light can only be seen from a relatively narrow field-of-vision. I would have preferred the tail-light to slightly offset the leftmost and rightmost LEDs so the tail-light could be seen by a wider field-of-vision. Because the field-of-vision is so narrow, take time to evaluate whether you've correctly installed the lights by moving 50 or 100 yards away from your bike, and looking to see how well the lights can be seen. (It's helpful if you work with another person to install the lights, where one person makes the adjustments, and the other stands far away to evaluate the results).4) Stupidly, you press the headlight button once to initiate a blinking action, a second time to have a steady beam, whereas the tail-light is just the opposite -- click once for a steady beam, twice to initiate a blinking action.In short, recommended!
