Lighting

Beyond headlights and tail lights, BYD electric vehicles feature extensive auxiliary and interior lighting systems that enhance safety, convenience, and cabin ambiance. This category covers front and rear turn signals, reversing lights, fog lamps, interior cabin lights, step lights, door courtesy lights, ambient lighting strips, ceiling perimeter ambient lighting, storage box lights, dressing mirror lights, and charging port indicator lights for BYD Atto 3, Dolphin, Sealion 7, and Denza D9. These LED-based assemblies are controlled via the body control module and must match the original CAN-bus protocol for proper dimming, color temperature, and activation behaviour.
