3-Prong Wig Wag Flasher
Also available as a kit (with bracket/harness), CEC Part # EF30WWK
This flasher has 3 prongs.The prong marked must be connected to the 12 Volt (battery) through a switch, the other two prongs are connected to the lamps. Each lamp should draw at least 10 Watt.
If you are using LED bulbs, or other bulbs that do not draw at least 0.8 Amp, you should use our LED-compatible flasher (EF30AL)
IMPORTANT #1: It is important that the X prong be wired to +12 Volts through a switch. If you don't, it will click and flash your lights ALL THE TIME
IMPORTANT #2: If your vehicle is wired for a "regular" flasher, you cannot simply plug in an alternating flasher and expect it to alternativey flash front and rear, or left and right. If that's what you're looking for, additional wiring is required.
Please review the specifications for suitable wiring harness.
