Our Dual Tone Bike Horn and Light

Really long story short, we developed this dual tone bike horn and light. First, we discovered the Piezo speaker and its circuitry barely taxed the battery to drive the sound. Sitting right there in front of us, we had everything we needed to add LEDs. So, we ended up combining two products: a beacon light and a horn into one small and (we think) beautiful product.

Dual Tone Bike Horn and Light
This is the second Orp Engineering Mule.

Orp was started by Tory Orzeck, an industrial designer in Portland Oregon. He is a former GE Plastics and Nike designer before co-founding FUSE.   FUSE is a boutique industrial design consulting firm. FUSE does award-winning product design and development work for some of the largest brands as well as some of the newest. The work spans from athletic footwear, building and construction products and electronic enclosures to contract office furniture and sporting goods.  You can view more of the FUSE team’s work at fuseid.com.

In addition to the more reactive FUSE work, Tory always works on some sort of proactive science project. These are projects outside of  FUSE that he thinks is just a good idea. The goal of these projects is to
make something as a portfolio piece and or a try to sell or license to an existing manufacturer. A recent example of this sort of project is the Gerber Steady.  Tory patented the idea of a multi-tool that doubles as a mini tripod able to hold a smartphone or a point and shoot camera. Tory licensed the idea to  Gerber legendary blades and within a year the project was released.

Orp’s development was prompted by a couple of well-documented bike accidents in  Portland, Oregon.  Both riders were right hooked by commercial trucks
within the city. In both cases, the riders were neither seen or heard by the drivers. Tory wondered if there as a way to make cyclists more visible and or maybe more “hearable” to drivers.  Existing bike bells are just not loud enough.

It started with just being a really loud horn

Tory assembled a small team of an electrical engineer and a sound designer and set out to make an attenuated super loud and super small bike horn. This was to be a horn with a gas pedal like actuator so that a small displacement yields a friendly sound{76dB} and a larger displacement produces a  super loud 96 dB sound. We built breadboards and it all worked.
To keep it as small and green as possible,  we powered it with a rechargeable Lithium-Ion battery. We soon discovered that the battery was barely taxed to sound the horn. It was also very apparent we had everything to power a set of LED. This would allow us to turn our horn into a literal chimera of both light and sound.  Commuting cyclists all know they need a light so it seemed pretty logical to combine the two products into one. And,  what would become Orp, would still be super small.

Orp has one big button on his back that serves as Orp’s Mode Control.  It works like this:

  • Press for 3 seconds to power up. Orp’s horn is ready
  • Press again for battery status and the LEDs go into  slow strobe  mode
  • Press again for battery status and LEDs go into fast strobe mode
  •  Press again for battery status  and LEDs go into Constant On mode
  • Press for 3 seconds st to completely power down

The product is easily removed for avoiding theft and easy recharging. Orp was also designed to be highly serviceable. For example, if a mechanical part is damaged or broken, it is easily replaced.


While developing Orp,  Kickstarter came on the scene. Kickstarter is a crowd-sourced funding platform that allows creatives of all sorts to exchange rewards for small amounts of capital which can then be used for funding a project.
With Kickstarter, developers set a funding goal and if they meet that goal within a specified amount of time they get the money to fund the project and fulfill the rewards/pre-orders they’ve promised their backers.
Thanks to the backers, the journalists, and the media that covered Orp, the campaign was successful. This website is the serves to provide detail and news about Orp, and if customers want to buy they can do so right here, I mean, here.


Orp’s mission is to make human-powered activities safer and more fun.


The team is charging forward with great enthusiasm to get the word out and expand Orp’s line. We are working hard to learn from our users,  to refine our innovations, and realize new technologies that can make us safer and perform better. Of course, we will continue to strive for building highly functional, compelling and beautiful products.
