Abstract
Light bar assemblies configured to be mounted at a rim of a steering wheel of a vehicle are disclosed. The light bar assemblies can include components of a driver monitoring system. The light bar assembly includes a PCB bar having a plurality of visible and infrared LEDs and a LED driver. The PCB bar is coupled to a support plate of an outer shell surrounding the PCB bar. The support plate transfers heat generated by the LEDs and LED driver away from the PCB bar.
