RevoLights ARC LED bicycle fender with integrated blinky and brake lights

Revolights, which has launched two wheel-based bicycle light systems on Kickstarter is back for their third act.

The Arc LED light system is an add-on product that fits onto existing fenders, letting people simply add it onto the fenders of their choice. There’ll also be two complete options, one with a plastic universal fender and one with a higher end metal fender.

“The design is able to conform to different shapes,” says Drew Ocon, Revolights’ marketing manager. “All of the electronics we’re using and the plastic itself is pretty flexible. Not only does that allow it to curve to the shape of different size wheels, but also open or close (think hot dog bun) to fit wider or narrower fenders, too.”

The built in sensor detects deceleration, trigging the lights to become a solid brake light when you stop. The blink pattern will also speed up as you slow down, providing plenty of visual cues to drivers that something’s changing. Video intro, pics and more below…

The stretch goals double up on the project a bit. They want to add turn signals, which would be controlled by a small wireless toggle switch on the handlebars.

Help fund the project and you can get one for as little as $69. Pledge $629 and you’ll roll away on a Public V7 bike with the Arc light fender preinstalled. Plenty of other options are up for grabs, too. Check the campaign here for full details.


  1. As much as I loved my original Revolights, they always had a bit of impracticality associated with them–tricky installation, any little misadjustment would unbalance the wheel, and very limited rim compatibility. This, however, looks like it’s going to be a real winner. You get the best features of Revolights–the visibility and uniqueness–in a more practical from factor. These will make a great addition to my bad weather bike. (Where the original Revolights ended up just making lots of nooks and crannies for mud and street debris to get caked in.)

  2. I’d love a matching front end version of this – not for primary lighting but for visibility like the wheel mounted version.

  3. I think it would be better if the “brake” sensor actually measured when cable was being pulled. That way you wouldn’t have your brake lights go off every time you decelerate, for example when hitting the bottom of a hill. I’m not sure what the best way to implement this would be, but I think it would be more sensible and you wouldn’t get so many instances of “false” braking.

  4. I’m not sure I’d want to compare my fender to a hot dog bun. They always seem to break in half when I try to split them…

    My guess for the brake sensing tail lights is that you have a threshold of deacceleration that is met when actively braking to a stop but isn’t met when the road turns uphill, but I might be wrong. I think that at some point in the near future we have the equivalent of Di2 that actuates brakes as well as a derailleur. When that happens, sensing that the brakes have been actuated is fairly simple. In the meantime, you don’t really want anything sensing cable motion because it’s likely to make brake modulation and response feel worse, like a gunked up cable.
