Frequently Asked Questions
It’s simply too bright. Just like car fog light, you don’t want it on all the time. It’s too distracting for other road users. The change in speed and intensity is also more effective in attracting and maintaining attention. It also allows a much longer runtime from a light which is compact and lightweight.
See.Sense. selects its power output based on your situation, so it can be bright all the time and really bright when you need it most.
See.Sense can also be personalised, so you can select the behaviour you want (see questions below).Last updated:

Yes. We offer a full one year guarantee.
Every light is carefully inspected and tested before being assembled and packaged by hand. These lights are ambassadors for us and for our future brand. We take a lot of care to get them right. Our engineers are right here in the UK and pride themselves on their craftsmanship.Last updated:
A lumen is a measurement of how much light a source emits. It takes into account the sensitivity to the human eye to the wavelengths emitted. So it’s a pretty good indication of how bight something will look.
But what you really need to know is that every version of See.Sense. is brighter than the car lights you see on the road every day. This enables it to stand out against traffic signals and the lights on other road users, like cars and trucks.Last updated:
Yes. We're finalising a new user interface which will enable you to personalise your light. It will allow you to control which sensors are active (or turn them all off), the power level and the flashing/constant mode selection.
This will enable you to set up the light for exactly the way you ride.
To learn more, see the personalisation question below.Last updated:
Yes. We've been working a lot on personalisation features, to help make the light your own. No two riders are the same and so no two lights need to be the same either. It works out of the box, or you can set it up just how you like it. It’s up to you. It’ll remember what you've set.
See.Sense. will enable you to select the following items:
- Main Sensor On/Off – select On for reacting to the road and to your movement. Select Off to turn it into a regular light
- Light Sensor On/Off – select On to react to car headlights and dimly lit areas. Select Off to turn into a regular light.
- Power level High/Medium/Low – select High for maximum performance, select medium to extend runtime with moderately reduced performance. Select Low to maximise runtime.
- Flashing On/Off/Morse – select On for flashing, or Off for steady (constant) running. Morse mode is for the custom message in the GEEK version only.
By default the light is set to : Main Sensor ON, Light sensor ON, Power HIGH, Flashing GEEK/ON. See.Sense will then behave exactly as described in the video. It’s deciding while you’re riding.
If you wanted to have a constant (Steady) light which changes in intensity when needed, set the light as Main Sensor ON, Light sensor ON, Power HIGH, Flashing OFF.
If you just wanted a really bright flashing light, set the light as Main Sensor OFF, Light sensor OFF, Power HIGH, Flashing ON.
There are 24 possible modes for most editions, with the GEEK editions having 36 possible modes.
See.Sense. has no switches, so these options are accessed through motion gestures and single or double taps. We’ll produce video guides to walk you through how to do it.
Are there any other options you’d like to have? Drop us a line, if we like your suggestion, we’ll add it!Last updated:
Yes. Saddlebag mounting is possible for the majority of bags. The bungee will enable connection to most mounting loops designed for clip lights. We have done limited testing, but found that the bag can absorb some of the vibration frequencies we use to determine the road surface. This makes the light slightly less sensitive in detecting the brake grip zone used at many junctions. What does that mean? In saddle bag operation, the light may take half a second more to identify that you are at a road junction or roundabout.Last updated:
Yes. The variation in brightness is mainly down to the efficiency of the LEDs. White LEDs are more efficient than red ones. Our Intense lights use a more efficient (and more expensive) variant of the LED used in the standard light. All the LEDs run the same power levels (watts), so all have the same runtime.Last updated:
Yes. As you know, rechargeable batteries start to lose capacity after a few years. See.Sense. uses a high performance RCR123A rechargeable battery. This has a high energy density and doesn’t exhibit the memory effect that degrades other types of batteries. We will make spares available in future, or you can easily source your own.Last updated:
We're very lucky to have a large group of testers. They're wonderful people who cycle long distances in all weathers to help us refine and improve the lights. This group has already cycled long distances to provide us with a huge repository of test results. This has enabled us to test the light extensively.
We're happy to note backers who would like to be testers. Just drop us a note and we'll tag your pledge. And if the opportunity presents, you'll be the first to hear from us.Last updated:
Yes, we a £5,000 ($8,000) Flir e50. Thermal management is really vital in making a good light since LEDs produce less light as they heat up.
A lot of manufacturers quote theoretical or calculated lumen output. Many don’t factor in heating of the LED. We’ve seen lights that quote 80 lumens and in reality produce less than 30 lumens when hot.
We invested in the thermal camera so that we could iterate the design to improve its thermal efficiency. Getting heat away from the LED quickly, reduces its operating temperature and increases the light output.
We’re really glad we bought this essential tool, it’s helped us extract 30% more light (for the same amount of power use) and run the LED much cooler than our first designs.Last updated:
Yes it can. A group is more visible due to being larger than a single cyclist. Therefore you don’t need the highest brightness settings (which could be annoying to your fellow riders). We’d suggest using the built in power selection to reduce the output to Medium or even Low.
At the moment, the sensor suite has no ability to determine you position in the group.Last updated:
Yes. A lot of our testers have aero posts and so it made sense to come up with a solution. The rear of the case is already domed to help it mate to a standard seatpost, so that’s a good start. We then used Sugru, a really great mouldable, self setting rubber fixing.
It's pretty simple to do: cover the seat post with cling film so that the Sugru doesn't stick, put some Sugru on the back of the light and press it onto the post to get the perfect shape. Let it dry. Take it off and remove cling film, then refit. Job done – a custom light mount that won't move around.
We’ll put some photos up soon. The black Sugru we’ve used is hard to photograph, so we’re just waiting for some coloured Sugru to arrive so we can show you just how simple and neat it is.
If you’d like us to add a pack of Sugru to your order, just pledge an additional £2. We’ll check with you before we ship to ensure we have your order correct.Last updated:
Yes. We met the £25,000 stretch goal and have added programming pads to the circuit board for all versions.
To program, you’ll need an Atmel AVRISP mkII and the free Atmel Studio software. You can program in C or AVR Assembly (ASM). The programmer is widely available, but if you would like us to send you one, simply increase your pledge by £40 and we’ll ship everything you need (apart from a PC or Mac!).Last updated:
