Description of Change: A new rocker switch is now available for activating the head lamps and marker lamps on the listed off highway trucks and tractors. The new switch has four sets of switch contacts rated for a maximum lamp load of 10 amps per contact. This provides a higher electrical load capability than the previous switch.
