Cygolite Streak– 450 Lumen Bike Light– 5 Night Modes & Daytime Flash Mode– Compact & Durable– IP67 Waterproof– Secured Hard Mount– USB Rechargeable Headlight– for Road & Commuter Bicycles , Black

This headlight is very bright and fits any of my needs while night riding. The adjustable settings allow for a brighter "constant beam" setting for a little extra visibility or a dimmer "constant" setting to save batteries. I ran with this for about a dozen or so night and some day rides before the first recharge. There are also flashing settings for better visibility to cars but I do not personally have a need for those. I think the 350 lumen is enough power to illuminate a trail or road and still get good rechargeable battery life. Another bonus, the light is light and sleek. I use it on both a road bike and cyclo cross bike, the ounces and wind resistance are not noticeable at all. The quick release clamp allows for removal if the bike is being left in a public area and it fits wide handlebars as well as narrow handle bar extensions.The only con I have had so far: The rubber gaskets inside of the quick release do fall out and I lost the top gasket on both of the lights that I own. The quick fix is to rubber cement them on before you ride. In the long term the company should seal them in place more firmly at the factory. For me this was not a big enough con to drop the product below 5 stars.

Man; this light is off the chart; I was wondering why It wouldn't shut off right away; it has several settings and it gets extremely bright I've heard comments like he has a new light it's that bright. My one problem with this light is the elastic around the seat stem for the rear light is too small; but I use twist ties and they firmly secure the rear light. All in all this light is an excellent value for the money

Love the ease of being able to slide the light off the bike for charging, just after two hours of use It starts to tell me it needs a charge it blinks for me to know. I like the warning and it doesn’t take long to charge just wish it lasted a little longer. I go on night rides for safety. Not as many people out in my area and it’s comforting so I don’t have to dodge cars or people and I can ride semi relaxed. I just wish after two rides I didn’t have to keep taking it off my bike. I did buy a backup light just in case so yes I have two now.

This light is fantastic. Great build quality, very clear, bright light with both a spot illumination and a softer peripheral illumination. The mount appears sturdy and is very easy to mount, plus the release is easy. Charges via USB, which is very convenient. The modes are easy to switch through, plus it remembers the last mode you were in, so you don't have to cycle through all the modes again when you turn the light off and on. I can't imagine why anyone would need a brighter light unless they were doing down-hilling at night. I cycle commute 6-7 miles each way and then do long weekend rides, sometimes spilling into the late evening. Even in pitch-black, I have full illuminatio of the road. The high-beam mode is probably even too bright for cars. The light is lightweight, bright and well-priced. What else do you need?

This light is a substantial upgrade over my previous light in terms of light output and features. And it stays put on my bike, which is the real reason I made the upgrade. The price seems like a reasonable value for the light output and the build quality.It uses a usb mini cable to charge which has been deprecated 10 years ago.There are several light settings and flashing options. I think it's a bit overkill for my needs. However, I do wish there was a flashing mode for the lowest light setting to extend battery life. I probably won't need the high or boost settings during my normal urban night commutes. But I like that try are there for when I do need them.Finally, the light is small, looks slick, and easy to install.

Very bright and small with a bunch of lighting modes. It was more then I wanted to spend on a light but was rechargeable.Did not last long for the price though. Battery has already gone bad and won't hold a charge. If I leave it sit it will be dead in a day without it even on.If I had done more night rides I doubt it would have even lasted this long. If you need a bright small light it isn't bad but the battery reliability is poor and expect to replace it after 2 bike seasons.Warranty is only a year. Guess I know why now.

I'm very impressed with this light! Albeit I've never used it alone, (as I have another light on my handlebars) I did try using it alone once, and as another reviewer stated, it cast somewhat long, and sometimes deep shadows, to where I could'nt tell the difference between a pothole and a 'rise' in the pavement (probably from water getting under the pavement through a crack, then freezing and thawing, thus leaving an uneven spot in the pavement) but having the other light (which is a flood) helped. Albeit the flood light does'nt go far, this light (which is a 'spot' type) is just what I need to help me see further into the darkness. This light usually 'spots' the pavement WELL in advance for me to slow down, then my 'flood' light illuminates the area enough for me to know which direction to go in to avoid the hazard. (I try to stay on the road, if I can)This was just what I needed for an additional light to my flood to help me in the dark! The one thing I like, is that If I'm in the city (I go from urban [city], to sub-urban, to rural (no ambient light), back to urban during my commute) the "Daylightning" mode is great, since I can both be seen (necessary for city commuting) as well as see when it's dark, because it flashes while it stays on! Albeit on high, the battery won't last as long as a "Cygolite Metro", because the "Streak" is only 3.5" (88.9mm), whereas the "Metro" may only be 4.0" (101.6mm) .5" (12.7mm) longer, it is also 0.3-0.5" (7.62-12.7mm) wider,thus allowing for a larger battery. Still, if all you really do is commute, this is the perfect light for you!

This light is awesome. Well worth the price. Bright, easy to install and has a large range of adjustment. Can be adjusted Up, down, inwards and outwards allowing the user to adjust the light to be pointed in basically any direction. Lots of different light modes as well for a range of uses.

Bought this light in the middle of the winter, half a year ago. After the 1st charge it worked as expected for one month, but slowly dimming without any low-battery indication. Then, it suddenly turned off. After charging it it happened again, but now only after ~30 minutes of use on the steady pulse setting that should last for about 3 hours. And after another charge - same behaviour. I contacted the seller and sent it back to them to test the fault. They couldn't find anything and sent it to the supplier. After about 10 days they contacted me to tell me that they couldn't find any fault and will send it back on my own expense. I assumed that it was related to the cold weather. Not saying that it's a good excuse but maybe the battery somehow fail in the middle of the winter. Since then the light is in the drawer. Yesterday (June) I took the light out from the drawer, charged it for >4 hours. It doesn't even turn on.In summary, I'm very disappointed from the product. No chance that I will buy any product from this company again.
