Bicycle light trial – Light Insights Trial (LiT)

To fill out our Expression of Interest form, please scroll to the bottom of the page.

The LiT trial is now underway

The TAC is collaborating with Deakin University, See.Sense and the iMOVE CRC to run an Australia-first trial using See.Sense’s smart bike light technology. The technology will let cyclists who participate in the trial share insights which will go towards understanding how they ride and what impacts their safety. If the trial is successful then the insights could be used to help inform future policy planning and infrastructure improvements for cyclists.

About the trial

One thousand Victorian cyclists, of all abilities, have been specially selected to participate in the LiT for the next 12 months. Participants will be out riding using See.Sense’s ACE smart bike lights which will enable them to share data through an app that will offer the research team insights. The technology allows cyclists to share:

  • Cyclist crash events – including mapping collision and close pass hotspots
  • Abrupt Accelerations or Decelerations
  • Swerving
  • Road Surface Roughness
  • Average and Instantaneous Speeds
  • Dwell time
  • Origin-Destination and key routes/gateways
  • Cyclist feedback

For participants

For those who have been selected as part of the trial, you can find FAQs and how-to videos to set up your lights below. If you have any questions contact us at

About the technology:

The technology being used is a smart bike light developed by See.Sense. This light is a world-leading technology for cyclists that has been trialled in multiple cities including Dublin, Birmingham, Manchester, Oxford and Antwerp. As well as capturing ride data the lights provide an added layer of safety by reacting to its environment, flashing brighter and faster at riskier moments such as roundabouts, road junctions, filtering through traffic or approaching car headlights.

Participant FAQs

How does the Light Insights Trial (LiT) bike light work?

The bike light is the product of See.Sense a company that creates cycling technology products to make cycling safer and to engage the community in insights. Find out more about the See.Sense technology here.

How much data does the app use?

It depends on the phone, but for every hour of riding, the app will use about 1-2MB (about the same as uploading one photograph). If not riding, the data use is negligible.

How much phone battery will the app use?

It depends on the phone, but one hour of riding will use approximately 10% of the phone’s battery. If not riding, the battery use is negligible.

How do I get help with the lights or the app?

How does the light collect data?

The patented sensor and communications technology inside See.Sense lights identifies 800 sensor recordings/second. It then applies artificial intelligence to perform 32 million operations per second on these readings. The light then sends this processed data via low energy Bluetooth to your smartphone, then your smartphone sends the data to the cloud. It’s this combination of our patented hardware and app that allows See.Sense to gather never-before-seen insights that are simply not possible using an app alone.

What data is collected by the light?

The technology will gather data such as crash events, near miss incidents, abrupt acceleration and deceleration, swerving, road conditions, average speeds, dwell time and rider feedback.

When does the See.Sense light collect data?

To collect data, you must have your light on, be connected to the app (in the background is fine) and have agreed to the terms and conditions for data collection for your project.

How do I know if I am collecting data?

If you are collecting data, you will see your Ride Stats change in the app and occasionally you will be prompted to fill in a post-ride survey.

What does See.Sense do with the data?

See.Sense aggregate and depersonalise the data before sharing analysis and insights with Deakin University. As this data will be collected for the Light insights Trial (LiT) you will be given a project code so that your data can be anonymised, aggregated and shared with the research team at Deakin University. You can see examples of analysis from similar See.Sense projects here.

What data privacy controls are in place?

Ride insights can only be collected when you have opted into cycling insights in the app and agreed to the See.Sense Mobile App Terms and Conditions and Mobile App Privacy Policy. You must then have the app open, or on in the background, and your light needs to be on. The See.Sense mobile application gives the user the option to set privacy zones within which no data will be collected. It is recommended that the user include their home within their privacy zones.

Users can ask See.Sense to delete data at anytime. This will also be deleted from the Deakin University systems as well.

Why do I need to allow location settings?

The light doesn’t have any in-built GPS components (they would use too much battery life) so See.Sense relies on the phone’s GPS to pair location with the data collected by the light. Location settings are also required for crash alerts.

Can I run other location-tracking apps at the same time eg. Strava? And will it drain my battery if I am using both?

You can run the See.Sense app at the same time as other location apps such as Strava and Map My Ride. In terms of battery usage, apps using location data will use around 10% of your battery per hour. When you run a second app, this will bring total battery usage to around 12% per hour (depending on the make of your phone), which does not represent a significant increase.

Do I have to keep my phone with me when I cycle?

Yes, your smartphone will have to be with you on your ride and also connected through our app to the light (keeping it on in the background is OK). This allows for data to be collected and then sent to the cloud via your smartphone once your ride has ended. Your phone doesn't have to be on your handlebars, it can be in your pocket or backpack.

Do I need to cycle differently, e.g. cycle through potholes so they are flagged?

Not at all, simply cycle the way you normally would. The telemetry insights from the See.Sense light can detect road surface anomalies before potholes occur as well as any avoidance actions you take around large defects. Simply enjoy your ride as normal.

Why is the TAC investing in this trial?

The Light insights Trial is a project which will allow the TAC to uncover the opportunity that new and innovative technology and data sources offer. The TAC has chosen to invest in a technology for cyclists as data sources which provide road safety insights are particularly challenging for this road user group.

Why isn't the TAC just building better cycling infrastructure with this money?

The Light insights Trial is a part of the holistic investment in cycling safety being made by the TAC.

In addition to this trial the TAC invests significant amount in cycling infrastructure projects. Across Victoria, the $100 million TAC Safer Cyclists and Pedestrian Fund is delivering 44 walking and cycling projects. The TAC is also partnering with DoT as a part of the $13 million investment into the delivery of pop-up cycling lanes to help relieve congestion and provide an alternative to public transport for those living closer to the CBD.

How will the insights form the trial be used by the TAC?

The trial is being undertaken so that the TAC can understand if technology, such as the See.Sense light, can offer insight which can inform investment in safer cycling projects. In addition to the collection and analysis of data the TAC will also be undertaking an evaluation of the technology and trial findings.

Who are the trial partners?

The trial is being delivered in partnership with the iMOVE CRC, Deakin University and See.Sense.

Who is See.Sense and why are they a partner in this trial?

See.Sense is a company based in Belfast Ireland that creates cycling technology products to make cycling safer and to engage the community in insights.

  • Fixing the mount:
    • Slide O-ring into the notch in the bike mount
    • Place bike mount on seat post
    • Pull O-ring around seat post and loop over mount – again ensure O-ring slides into the notch on the mount
  • Attaching the light:
    • Fix light into mount ensuring light clicks in on one of the three mounting positions
    • Check light to ensure it is securely fixed to the mount and the mount doesn’t move on the seat post.

Please note:

Feedback from riders to the LIT team has indicated that the light clip that comes with the See.Sense lights can fall off on rougher (e.g. gravel) roads. We recommend fitting your light to the seat post of your bike using the clip provided by See.Sense. This video shows how to fix your light to your seat post using this clip.
