Note
For proper headlamp operation in Model Y vehicles, both headlamps must be of the same type (Global or SAE), and the vehicle software configuration must match the installed headlamp type. If one headlamp is damaged, and the replacement headlamp is not the same type (Global or SAE) as the undamaged headlamp, the undamaged headlamp must also be replaced. If an SAE type headlamp is damaged, replace both the damaged and the undamaged SAE headlamps with Global headlamps.
