If your light was purchased from a retailer in Germany, it will be one of our StVZO compliant lights. These lights are not compatible with Modemaker and cannot be updated, which is a requirement by German StVZO standards.
StVZO lights will give you an error or incorrect product ID and may attempt to register as a Bandicoot headlamp as default. Do not attempt to program the light as a Bandicoot as you will risk not being able to undo this and corrupting the lights software.
