Very bright and visible. Mine is blue. I wear it blinking. I wear it over my shoulder across my chest for comfort.

This headlamp is shockingly bright. So if your'e looking for a reading headlamp ... keep looking. This one's for seeing through the woods and down the trail a very, very, very long way. We go camping a lot, and we have three dogs that go with us. We typically take the dogs for a walk before we turn in for the night, and I needed something to help me navigate. I typically use the red light when I'm walking with my fiance, and the white light when I'm walking to the restroom facilities (he can actually see well in the dark, and the white light is bad for his night vision). I hope we never have to use the blinking red light. The band is nice and wide and comfortable on my head, and the bright color makes it easier to find. I can see us using this headlamp for years to come. I bought this at a discount for review purposes.

The claim to the be the brightest is not unfounded. It really is startlingly bright.  The elastic and foam backing on the lamp do make it comfortable to wear. There is the possibility of excess wire as the connector runs from the battery pack to the lamp, but I found it loops through the snap guides just fine.  Watched the product video to discover the use for the extra part in the box, which turns the headlamp into a bike lamp you can remove from the lamp and attach to some handlebars.  Do appreciate the versatility there.  Aims well and stays put.

Bought these for myself and a friend, and they are highly visible at night. The friend thinks these have saved his life on several occasions. Glad I bought them!

I love the fact that every body can spot you.  No matter if you  use it for running or cycling, it's very bright.

Very bright light and comfortable to wear.  Used it during 2016 Portland to Coast and was excellent to use in the middle of the night.  Highly recommend for use if running/walking at night.

This headlamp is comfortable and easy to wear, and frees up my hands for other tasks.  I use it to walk my dogs at night, and the light is more than adequately bright, enabling me to see quite a distance ahead.  The adjustable angel feature is perfect, and I can see where I am stepping right in front of me, or farther ahead. I've only been using it a few days, so I cannot speak to durability or lifespan, but so far I am very pleased.

Very bright, extremely visible, easy install.

The first mode, and the only mode I use, is a sort of random blinking mode and it is very attention grabbing. It almost looks like the strobes on an ambulance! Uses two AAA batteries, so hopefully battery life is good. I will update with more after I put some mileage on it!

This headlamp is great for biking at night, or for doing work in my attic or crawl spaces where you don't have light and need to be able to have your hands free. It is comfortable to wear and works great. It is very bright at its brightest setting. The strobe light is good enough for parties, but actually made me a little dizzy. Battery life is good depending on your batteries. It is easily adjusted and lights up what you are looking at. A sample was provided for an honest and unbiased review.

This light was a replacement for a previous bike taillight that died. I was concerned at first about its size, but it is very visible - the LEDs are powerful, and it can be angled to the best visibility. It comes with various ways to attach it to the bike or a pack, and I found the pieces versatile enough to come up with my own solution. A great buy for the money.

These shoes are very comfortable.  They are also very bright in color.  People will look at your feet if you are wearing these shoes, in this color.  Decent pricing also.  I recommend these shoes.

These are very bright and you could see across the room, and it brightens up the backyard up to 50 feet. I've dropped one and put it back together, it still worked! These have a plastic housing, unlike others which are made of some kind of metal. One of them now has a couple of flickering LEDs, while the other two I have still work. I have had them for four months which in that time I've only have to replace the batteries once; from moderate use. I would recommend these to anyone who want's a flashlight for camping, or doesn't like the scratches that happen on other LED flashlights.

These lights are terrific! They are bright so we are seen from far even during the brightest time of day. I bought them for my son and now my husband. It's a bit tough to be behind these lights as they are bright for the eyes, but the safety factor overrules.
