A clip-on handle grip increases the surface area of a handle. The method includes defining pixel sets S0, S1, S2 around a block boundary, selectively determining a deblocking mode as a default mode or a DC offset mode depending on the degree of blocking artifacts. The steering column extends below the vehicle to operate a front steering frame on which are mounted the front wheels. In other designs, the auxiliary power supply may be intermittently connected in series with the LED string only when needed.
