A method includes energizing a light source of a vehicular lamp assembly according to a duty cycle. The light source emits light responsive to being energized. While energizing the light source, and during an off-cycle of the duty cycle, the method includes transmitting an outgoing short-range wireless communication to a user device. The outgoing short-range wireless communication is transmitted from an antenna at the vehicular lamp assembly. During the off-cycle of the duty cycle, the method includes receiving an incoming short-range wireless communication at the antenna at the vehicular lamp assembly. The incoming short-range wireless communication is transmitted from the user device responsive to the outgoing short-range wireless communication.
