Riverside Manufacturing's SmartTek eight-button Switch Panel and Mini I/O Control Module allows a user to more efficiently operate a vehicle's electrical systems. The product is a solid-state, controller area network (CAN)-based module for electrical systems that power external headlamps, turn fans on and off, control internal dome lights and perform other functions. The Allen County (Ind.) Highway Department has installed the modules in several dump trucks so drivers can control functions such as activating the salt spreader, power take off, and controlling plow strobe lights.
