Great product and support from PDW

I've put it through the wringer

The Danger Zone puts out a very bright light. It also has a lifetime warranty. After one of my Danger Zones would not turn off, I returned it to PDW and they promptly replaced it. I appreciate a company that stands behind their products.

Fine.... 'til it disappeared.

I've used it several times

The Good: Bright and I liked the attachment system. The Bad: Just back from my third ride with this light to find that the front of the housing (the part with the lights and batteries) had become separated from the back somewhere on the road. I had had a fairly fast decent and hit a few potholes, but nothing out of the ordinary. Unless you ride only on extremely smooth roads, find something better.

First Impressions Are Great!

I've used it several times

After using this light for half a dozen morning rides, I have to say I'm very pleased. I went with the Danger Zone, rather than comparable models, because the DZ runs on AAA batteries. This means I can throw two AAAs in my stash pocket along with tubes, and multi-tool, and if my batteries dies, I can swap them out and won't end up a deadman. For extra credit, I use rechargeable AAA batteries making this a no-brainer for me, since USB charging ports are not mega durable on small electronics in general (and inconvenient when 20 miles from home and the battery dies...Now what you gunna do?) Another reason I went with the DZ light is the presence of two bulbs, which allows the light to double-team a driver's attention, making it more effective than a single bulb's dance. And, these bulbs are NOT SO bright that you'll scorch the retinas of the guy/gal behind you if riding in a group, so no worries there. Also, the three light modes are all I could ask for: a simple alternating top-bottom-top-bottom mode, a crazy schizo mode, and a steady stay-on mode give me all I need. Finally, I'm uber pleased with the mounting system, the STAYPUTNIK! It is easy to use to mount the light (not tools required), it's fast (probably 2-3 seconds to install or remove), and secure (it doesn't move around, but you can make micro-adjustments with your hand if needed). The mount is great and makes it even easier to fall in love with this light. If you're hesitant to drop $35 on a light, just remember you can't put a price on safety, and, ER visits can be terrifyingly pricey. Do it!

Fast forward 14 months and this little light is still going strong for me. It's very easy to mount, turning it 'on' and toggling between settings is simple thanks to the large button, and the battery life is better than expected.

Nice to read a helpful review...kudos!

light, cheap, simple

I've used it several times

It's bright enough for the expense and it's light and simple. Really not much you can take away from this light. It's not the brightest but it's not the worst ever. Good all around item

Great Commuter Light

I've put it through the wringer

Great little commuter light. Love the seatpost attachment which is an easy to attach elastic strap. High visible for only running on AAA's and a few setting to choose from. Burn time is definitely 50 hours, it's lasted a long time!

Rad Little Vid

A funny video put together by the neat folks over at PWD using their bike lights. Cool company!

This IS a rad vid. Thanks!

The Best!

Best rear light I have found. In use for two years on (especially) night and even day riding on New England roads. (bike lanes are rare to non-existent) I have actually had many people clear a full lane when passing later advising that they thought it was the rear light from a police stop. You will not be disappointed. Six stars please!


Will this mount to aero posts, and is it good for day time riding? Thanks
