Superior Signals has expanded its offerings of truck and trailer lighting products by including stop, tail, turn and back-up combination lights. Two functions are combined into one light. Drivers can signal reverse and either stop or turn patterns with a single light. Two options are available: a four-inch round light with 12 white LEDs and 13 red LEDs; or a six-and-a-half-inch oval light with 12 white LEDs and 14 red LEDs. Product codes are SY1425RCK and SY1626RCK. Each light comes with a rubber grommet and a right-angle PL-3 plug.
