When you need to "be seen", the Planet Bike BRT-3 tail light is just the ticket. Its weatherproof design is lightweight and durable.

This light can be seen from up to 2000 feet away, thanks to 3 super-bright LEDs and a parabolic reflector.

The BRT-3 is not only highly visible, its versatile! It can be attached to your jersey using the included clip, or mounted to your seatpost with the included mount.

Two AAA batteries (included) power the light for up to 200 hours.

Comments about Planet Bike BRT-3 Tail Light:

Good for when I need to occasionally run a short section of road on my mtn bike getting from trail to trail. I also leave it flashing during hunting season when I'm out in the woods.

As inexpensive lights go, this works well and is simple to operate. Off-on-blinking modes are straightforward. Mounting hardware has proven to be entirely reliable. It gets drenched and still works.

Looking at the projected beam pattern in a dark room, there is one bright "hot spot" in the center, with rapid fall-off in intensity toward the sides.

My friends and I compared it to a few other tail lights on a deserted section of road in broad daylight. We felt some of the lights would be the most visible thing in a driver's field of view during the day and would be immediately noticed even at a great distance. This one is not in that league. Nonetheless, we all agreed that a driver would be more likely to see you with one of these during the day.

At night, it is plainly and obviously visible. No problem.

No regrets, I'm happy with it.

        Comments about Planet Bike BRT-3 Tail Light:

        At it's core, a blinky light needs to be three things: bright, simple and reliable. The Planet Bike BRT-3 satisfies all three requirements easily. I bought one, loved it, lost it and bought two more Bright? My night riding buddies complain about it being too bright. Simple? On (solid)-On-(blinking)-Off. None of those fancy/silly special blinking patterns to have to cycle through trying to find 'Off'. Reliable? It always works! It also never jumps off the mount that it comes with, and I have taken mine on dozens of off-road night rides. My Planet Bike blinky has also seen thousands of commuter miles without issue. I've owned dozens of other blinky lights in my day, this is my favorite. Oh, it's only [$]bucks, too.

        Overall this is a very good product for street and light trail use. If using on rougher terrain I would suggest using strong rubberbands to keep the light from making a quick getaway when you least expect it.

        Bright and Cheap. What more could you ask for? It helps you to be seen on the road home. Long battery life is a plus. It was accidentally left on for a few days in a bag and still works great.

        This product exceeded my expectations as far as brightness and battery life. Although I bought this on sale, I would purchase it at full price.
