A steering wheel includes: a hub; a rim connected to the hub through a plurality of spokes; and a first steering wheel remote control and a second steering wheel remote control arranged on sides of the hub, respectively, in a symmetric manner. A biological parameter measuring apparatus includes: a first conductive bezel arranged around the first steering wheel remote control; a second conductive bezel arranged around the second steering wheel remote control; and a signal processor, which is electrically connected to the first and second conductive bezels, configured to process and calculate a biological parameter based on a signal detected by at least one of the first conductive bezel or the second conductive bezels. The first conductive bezel is spaced apart from the second conductive bezel.

Various implementations include a light bar system for a steering wheel of a vehicle that includes a high intensity light source, a light diffusing layer, and an outer lens. For example, in certain implementations, the light diffusing layer is disposed between a plurality of high intensity light emitting diodes (LEDs) and an outer lens, and the light diffusing layer causes the light from the LEDs to appear as a continuous stream of light across a length of the lens and provides sufficiently bright lighting to warn or communicate with the driver in various ambient lighting conditions. In certain implementations, the outer lens is colored to blend in with the rest of the steering wheel when the LEDs are not activated.
