Terms of Service
Last updated 30 August 2026
Safety and lawful use. MercLight is for a vehicle you own, used off public roads, for show and demonstration purposes only. Operating non-standard lighting on a public road is illegal in most jurisdictions. You are responsible for how and where you use it.
What the app does
MercLight sends the same kind of diagnostic commands a workshop tool sends, over a Bluetooth OBD adapter, to change how your vehicle's lights behave while the app is running. It makes no permanent modification: the vehicle returns to its normal state on its own.
Your responsibilities
- Use it only on a vehicle you own or are authorised to work on.
- Use it only off public roads.
- Do not use it while the vehicle is moving or in traffic.
- Comply with the laws that apply where you are.
No warranty
The app is provided "as is", without warranty of any kind. Vehicles differ, and we cannot guarantee that any particular vehicle, control unit or adapter is supported.
Limitation of liability
To the fullest extent permitted by law, we are not liable for indirect or consequential loss arising from use of the app. Nothing here excludes liability that cannot lawfully be excluded.
Acceptable use
Do not attempt to reverse engineer, extract or redistribute the security material the app relies on, and do not use the app to interfere with a vehicle you do not own.
Termination
You may stop using the app at any time and erase your data from inside the app. We may suspend a device credential that is being used to attack the service.
