If the light bar is designed and marketed for use on motor vehicles (including off-road vehicles), it generally falls under 851220 as electrical lighting equipment for motor vehicles. However, if it is a general-purpose work light not specifically designed for vehicle mounting, it may fall under the portable lamps heading (8513) or another lighting heading. The vehicle-specific design intent is the deciding factor.

Backup cameras and parking sensors are primarily data-capture or signaling devices rather than lighting or sound-signaling equipment in the traditional sense. They are more likely classified under the heading for transmission and reception apparatus (8517) or instruments and apparatus (9026/9029), depending on their principal function. Consult the relevant chapter notes or seek a binding ruling before filing.
