Is this light mainly for being seen, or can it be used to see bumps on the road ahead when biking at night?

This light is excellent at lighting the way. I depend on it daily to make sure I have a clear biking path.

You can see everything! You can adjust it so you can see 30 to 40 yards ahead if you want warning of upcoming obstacles or you can aim it down towarn roadway and still see a fair distance

You can see bumps etc.It s very very bright .if not for the size it may be passed for small motorbike light when approaching.

Extremely bright light - I do many nighttime rides for training and have no fear of bumps with this light. I tend toward mounting it on my helmet as it is a great option for seeing farther away the higher I mount it. Although I have no issue with seeing bumps, if one mounts this on the bar, then the bumps will also cast a longer shadow and be even more visible than they would with a helmet-mounted light position.

In my opinion, it is strong enough to spot anything ahead on the road by about 30 or more feet easily!

No, it has a buffer battery, so even at a full stop it is full brightness as long as you have ridden for a bit.

its weak unless you are using it on road and there are street lights. For mountain biking I would by one of the cheap 4000 lumen lights on ebay for about 30 bucks, that's what I did and it worked out great

Angela, As soon as you hit the road and start riding it starts blinking. I haven't yet seen how it looks when I ride in the night. But it should lit up entire rim of the tire as the light is fitted into the opening of the tire tube and when tire turns the light spreads across the tire.. If you are a night bike rider its worth buying this..low price and best

I dont believe so. But it does have a light blue hue to it though the light it gives off is fairly dull. You definitely wouldn't be using the light for a safety aspect when riding at night. However, if you're considering the light more for it's looks and design, its perfect! I actually ended up buying a mini led light from Trek (that I was mostly able to hide when mounted) so I could ride at night.

I ride a road bike but have used this at night on a tree covered trail that goes through the country side in the rain for a 25 mile ride 5 times a week. It does have multiple brightness settings. I ride a paved trail, I can see sticks, small animals on side of trail but it is flat. Not sure how shadows would show for bumps or dips in dirt.

The light is bright enough to make other bike riders stop at about 30 to 45 feet away. They say it blinds them. I had it point to high. As for total distance it is about 85 feet is a very very dark setting on the stand at the beach.

It's quite bright, but I'm not sure it would give you a sufficiently wide or lengthy cone of light to see ahead in the dark. The diameter of the bulb is only about an inch. But, it would certainly make drivers aware of you on the road if you clipped one to the front and one to the back of your bike. On the other hand, you can do that with reflectors.

Excellent questions. It will illuminate reflective street signs to a point, but I found I really needed two lights, one aimed ahead, for signs, pedestrians, etc. and one aimed down, for potholes and debris. In fact, I did buy two of these lights. I mounted the straight-ahead one on my handlebars and got a handy device to be able mount the downward one on my front fork, at wheel-level.As for illuminating an unlit path, this light is good if you ride at a slow, leisurely pace. You will "outrun" the light if riding im dark conditions at 10-15 MPH, though.In thd end, I settled on a 600-lumen NiteRider (lots of other, similar choices are commonly available now) to provide a single light for signs and surfaces.

Actually, it is quite bright (don't know how many lumens) and has a focusing feature, which means that you can go from flood to spot fairly easy. If you are putting up a tent in the dark, it will work fine. If you are caving, it will work good enough to see what is ahead of you, but I would suggest also carrying a much brighter light with you. If you are trying to use it for bicycling at night, it probably won't work for you. Did I cover all of the bases?! It should stand up in the rain - the battery compartment is gasketed, but I've never tried it on the rain.

Umar, This light is mounted on the back of the bike, facing to the rear--so i have no idea--however when i look in my rear view mirror i can see it reflecting off the road behind me--so i guess it would reflect off street signs. I use it on pulse mode and the battery last almost all summer long. I use this when i ride day or night to help bring attention to drivers that i'm on the road , making me more visible. The built in reflector makes this even more of a safety device in case the battery dies and you are not aware of it. A great light , i have one mounted on each of my bikes. I really can't say enough good things about it--easy to mount also.

I live in a city, so there are streetlights around, but I can say that the visibility is good. Hope this helps.

It's a fairly narrow spot. I use it on my bike but also working at night ( getting firewood this winter) but it's so dang bright you get a nice field of view. Great light! It's pretty much bright enough with 1 led on.. with 3 it's extremely bright.

I am pleased with how it works even during the day. But where I ride, I use one behind the saddle and one down low by the rear cassette to maximize visibility. As far as lumens, I do not know, but it is bright.

I had only use this on the road, but it's quite bright even in the pitch black part of the city. The helmet mount and bike mount are also very robust.

This light puts out bright light for about 3.5 feet in front on the bike. If you need anymore light than that, you need something else.

It is way brighter than my more expensive light, I use it when riding at night on the road, it is very bright
