1. A lighting fixture for a vehicle comprising:
- a lamp assembly;
a grounded reflector including;
a conductive thermoplastic layer; and
a metal layer having the shape of the conductive thermoplastic layer electrically coupled to a ground plane of the vehicle via the conductive thermoplastic layer; and
a capacitive switch electrically coupled to the lamp assembly to control the lamp assembly by detecting a capacitive object within a detection field.

Abstract
Apparatus are disclosed for a grounded reflector for a vehicle lighting fixture with a capacitive switch. An example disclosed lamp assembly for a vehicle includes a lamp assembly, a grounded reflector, and a capacitive switch. The grounded reflector has a metal layer electrically coupled to a ground plane of the vehicle. However, the metal layer is not directly coupled to the ground plane of the vehicle. The capacitive switch is electrically coupled to the lamp assembly to control the lamp assembly based on detecting a capacitive object within a detection field.
