Headlight fault warning light
What it means
The amber bulb-and-exclamation warning indicates a headlight fault. It is not confirmation that lighting is switched on.
What to do
Arrange inspection by a BYD authorised dealer or service provider. Check the accompanying headlight message and do not treat this warning as an ordinary lighting-status symbol.
