  1. does the job 3 Star Review

    the frame is nice. the light was installed properly and glue placed over the nuts to keep them from vibrating out. wiring harness is plenty long.

    my only gripe is the fact you cannot use a normal brake light modulator with it. when I hooked mine up to my airhead GS with a red porter led taillight it only flashed once then went solid. I don't want to spend $40 on a smart controller. it's so bright I don't want it flashing or even solid all the time, like being stopped at a stop light. if you want it to flash you'll have to deal with upsetting drivers behind you and it's kinda pointless to have it solid all the time. especially in california where it's only legal to have 4 flashes then solid. this does do that but it constantly repeats itself. there are several cycles that do grab attention.

    (red to power+ black to ground- and tap yellow to power+ to cycle through)

    also the option to have something printed on it is nice but it's just a sticker that who knows how long will last. I thought it was printed right on. mine came with ADVmonster logos that were not shown on the pictures.

    overall I'd buy it again but now I'm searching for a cheap timer that will keep it on a certain time when brakes are activated. I may be interested in the smart controller if more information was provided for it.

    Once I figured out how to cycle through the different modes the light works and functions fine. I used the ezcan but the light would not cycle until I hooked it directly to 12v. It would have been nice to have some more instruction on how this is done in the pkg.

    Works great, used the rear light and brake light functions of the ezan to have the auxiliary brake light run at a reduced output until the brakes are on then full power. Setup the auxiliary brake light to steady on by touching the red wire to the yellow which cycles through the different mode.

    I installed this on my 2014 Honda CB500X. Install was straight forward and very easy. The included Posi-Tap connectors made things real easy! The frame is metal and not flimsy, very rugged. The LED's are awesome and very bright! I would highly recommend this as an easy way to help be seen on the road.
