Dynamic Dashboard Lighting

The Car Inner Optical Grade PMMA Light Guide Plate enables dynamic dashboard lighting that responds to driving modes, navigation, or music. In sport mode, the dashboard can glow with a more intense, performance-oriented color. When navigation prompts a turn, a subtle light pulse can guide the driver's attention.

 

Adaptive Door Panel Lighting

Door panel lighting can adapt to passenger presence or activity, providing personalized ambiance or functional lighting. When a passenger is detected, the door panel can gently illuminate to welcome them. When they reach for the door handle or window switch, the lighting can brighten to improve visibility.

Interactive Center Console Lighting

Center console lighting can interact with touch controls or display information, guided by the plate's precise optical performance. When the driver's hand approaches the climate control panel, the surrounding lighting can brighten to highlight the controls. When a setting is adjusted, the lighting can change color to confirm the action.

 

Personalised Cabin Ambiance

The plate supports personalized cabin lighting, enabling users to create custom lighting scenes tailored to their mood or activity. Whether it is a warm, relaxing glow for evening commutes, a cool, focused light for early morning drives, or a vibrant, colorful scene for weekend adventures, the plate delivers consistent, high-quality illumination.
