Standard Ignition EFL-67 turn signal flasher for the 2003-2007 Chevrolet Silverado 1500 and other vehicles switches the turn signal lamps on and off so they blink. In the signal circuit it works as a relay that cycles current to the lamps.
A turn signal that stays lit, blinks unusually fast or slow, or does not blink at all can mean the flasher is worn. Before replacing it, look over the bulbs for burned filaments and the connector for corrosion or bent blades, with the vehicle off.
The 2003-2007 Chevrolet Silverado 1500, the 2003-2007 GMC Sierra 1500 and the 2003-2005 Chevrolet Silverado 2500 take this flasher as a direct-fit OE replacement, along with other vehicles. The 2003-2007 Chevrolet Silverado 1500 takes one. If your vehicle is not named here, look up its year and model in the "Vehicles it fits" section.
