Baywindow Bus Headlight Switch - 1971-79

This top-quality headlight switch with integrated rheostat is designed for Volkswagen Baywindow Buses manufactured from August 1970 onwards. Produced by DNI, this is a high-quality replacement part that restores correct operation of both the exterior lighting system and the dashboard illumination dimmer. The built-in rheostat allows you to adjust the brightness of the dash lights, an essential feature for comfortable night driving that is often lost when original switches wear out.

The switch mounts securely to the dashboard using the correct M10 x 6 escutcheon, ensuring a proper factory-style fit and clean appearance. Worn or faulty headlight switches can cause intermittent lighting, overheating, or complete lighting failure—this replacement resolves those issues while maintaining originality and reliability.

Manufactured to meet or exceed OE specifications, this DNI switch is ideal for restorations, electrical repairs, or preventative maintenance on late Baywindow models.
