iSeeTheLight is a programmable identification (ID) strobe light for boaters, campers and all outdoor adventurers.

"Light ID" concept

For many centuries, people use different kinds of lights to be able to see their assets at night. Lighthouses, navigation lights on boats, strobe lights on bicycles, you name it. All these lights serve one purpose - to allow you to locate something in the dark. Most of them, however, were not designed for you to be able to identify your particular asset among many other similar ones, for example your particular boat on a busy anchorage among 50 others. For that, you need some kind of a unique light signal, and unique means you should be able to choose it, so that it will be different from any other light sources around. This is exactly what iSeeTheLight is designed for. Using a programmable combination of different colours and durations, you can easily produce your unique "light ID".

What can I use it for?

iSeeTheLight was designed with night time outdoor activities, such as boating, sailing, cruising, camping and alike. The casing is strong and weatherproof, so you don't need to worry about it at all. Of course, you can use it for any other purpose too, if you have any interesting use case in mind please let us know!


Semi-transparent 3d printed casing with a lid at the bottom and a lanyard at the top. Power switch is located under the lid. THe normal working position of the light is vertical, which helps to keep the lid weatherproof, together with the silicon rubber O-ring.

The project was originally conceived around late 2013 after one of the regattas, where lack of such light was very obvious and frustrating. First hardware prototype was created in April 2014. First public demonstration of electronic prototype happened in December 2015 on Christmas meetup of a local Hackware community. First prototypes of the complete device with the casing and Android app were completed around June 2016 and field tested since then on numerous occasions, including the famous Neptune regatta. After getting some positive feedback from the sailing community, crowdfunding campaign was launched on KickStarter on 21-Mar-2017.

Where to buy

* "Duty cycle" means percentage of time the light is on, e.g. 1 second on 3 seconds off is 25% duty cycle, 1 second on 1 second off is 50%.




What if I forgot what light signal I set?
Just open the app and tap "replay" button. You don't need to be connected to your light for that. Video
Can I control multiple lights with one phone?
Yes you can, see this video for an example.
