On the left is this product, and on the right is the Planet Bike Superflash.

The Planet Bike Blinky Super Flash Tail Light has been the gold standard for many years. It had a single half watt LED and two additional less bright LEDs that flash using a flash-pop arrangement that keeps at least one lamp lit almost all the time so that drivers of cars can always see it. Off axis visibility was good, so that it didn't have to be aimed directly at the driver. It was waterproof and you could drop it repeatedly without breakage. I own several of them and have been very happy with them.

But they suffer from a few shortcomings. First, they have a short repeat sequence. Drunk and high-on-drugs drivers can get mesmerized by such a sequence and will run right into a light like this like a moth to a flame. So I've been using the superflash on the sides, not the back. Second, they are very bright up close, but from a distance, with lots of other distracting lights, they get lost in the crowd. A half watt isn't very bright when there are many other 12 volt sources of light. So in a big city, they are less effective.

Enter the Portland Design Works Danger Zone. It has two half watt LED that punch through the clutter of other lights in a city, and a longer repeat pattern making a drunk driver less likely to hit you with one of them. You can see from the video that it seems much brighter, though if you stop the video right at the end, both lights have a single half watt LED on at the same time and you can see that, at least at that moment, they are both identical. Otherwise, it seems well built, waterproof and off axis visibility is just as good, just like the superflash.

I agree with all the good reviews - it is one of the brightest and lightest lights on the market.
It is also one of the more expensive lights and worked perfectly for me for almost a year.

It finally broke...how? one of the 2 plastic clips that is released to change the batteries snapped off while I was opening it.
The light still works and now needs a tyrap or rubberband to hold it in place.

I guess if they were screws one would have stripped them out if you are not careful. So be very careful when you open yours up.

*update - PDW is shipping me a replacement clip. They have a warranty RMA form on their website.

I had three Tail Lights on my Bike (NiteRider CherryBomb, Planet Bike Superflash and the Blackburn Mars 3.0). I needed to upgrade so I got the Portland Design Works Danger Zone Tail Light to replace the Planet Bike Superflash as the main center seatpost Taillight.

On night rides and night bike commutes, the Danger Zone tail light is a nice choice for being seen. This is a bright light in a small package, and is helpful for making sure you get distinguished as a Bike from behind at night. It is the same size as the NiteRider CherryBomb, Planet Bike Superflash, and the Blackburn Mars 3.0 Taillights. Includes 2 cheap Chinese AAA batteries, and a seatpost and seatstay mount.

It is noticeably brighter than my Planet Bike Superflash and a bit more brighter than the NiteRider CherryBomb, which only has one 1/2 watt LED light. The CherryBomb is quite a bit brighter than the Planet Bike Superflash. The CherryBomb's beam pattern is wide, thanks to the collimator, so off-axis visibility is pretty helpful for a stand-alone taillight but to get it aimed level is so hard, the beam is often off-target, therefore I needed another bright tail light.

The Danger Zone has Two 1/2 watt LED's with three light settings.

Flashing mode #1 - Very slow Flash but very bright - (top LED light, bottom LED light, then both LED lights, etc). Good for dark residential streets or bike paths or locations comparatively free from heavy car traffic. TWICE the brightness of Flashing mode #2 but not as fast or "Super Flash" bright attention getting. I'd use with another bright tail light as it's Very slow.

Flashing mode #2 - Super crazy, Flash bright, attention getting for 1-2 seconds then Slow for .5 seconds then Super Flash, Slow, etc.

This light kicks ass, super bright and a great random flashing pattern. Drivers may confuse you with a cop that has pulled someone over. Expect wide berths from passing cars.

I purchased what I thought was going to be the Portland Design Works Danger Zone Tail Light. What I received was far from it - what I received is a knock off. Also, they didn't even bother to ship a locking nut so I can't even install this tail light if I wanted to. What a joke, never again. I know I should have just bought directly from the Portland Design Works website. I have attached pictures of the knock off that I received which looks to be a "Raypal RPL-2230"

The back part doesn't always like to stay on, but it's bright and easy to operate with gloves. A recent wet weather ride made it so I couldn't turn it off without taking out the batteries. That stopped after a week or so and it went back to normal.

I once landed a jump pretty hard and the red plastic light portion fell out and was run over by another cyclist that was behind me. I put it back in and it worked fine.

EDIT- I had another one go out on me because of the rain. This time it sometimes can be turned out without removing batteries, other times I need to take it apart. I'll probably try something that's sealed from the elements better next time. It'll work for you if you don't ride in adverse conditions though.
