- White or amber-colored lights are permitted on the front of vehicles, with certain restrictions on intensity and height.
- Red or amber-colored lights are allowed on the rear, with specific rules regarding placement and visibility.
- Blue lights are generally prohibited, except for emergency vehicles.
