VCCA Home Forums TECHNICAL - GENERAL Trucks and Vans flasher for guide 6004 signal switch

What kind of flasher do I need to operate the guide 6004 4 wire flasher. I have upgraded the wiring to 12 volts and Im using dual filament bulbs. One filament for brake lights the other for signal lights. I am using another single filament bulb for running/license lights. I need a flasher that will flash when using the one dual filament bulb. Any help appreciated!

You can decide yourself by looking at the socket that holds the flasher unit. It will be a 12-volt unit and most likely a three prong unit. I am not familiar with the 4-wire flasher unit. Most units are either 5 or 7 wire.

Ray the flasher to be used will be in a 38 chevy pickup truck. I have no fuse panel thus no flasher holder. It will only be mounted under dash some where.

I know it will take a 3 prong flasher. What I don't know is what kind. Since it will only be flashing two bulbs plus the single pilot (indicator light)on the Guide 6004 switch I need to know what kind of flasher has the least amount of resistance for the flasher to work.

Most flashers have to have more resistance than a single bulb to have enough resistance to operate. I am only trying to flash the two bulbs in the left and right tail lights since I have no signal lights on the front of the truck. Resistance would have to be at a minimum to work wouldn't you say?

The flasher socket is normally a part of the directional switch unit. It sounds like you will not have a signal for the front? The characteristics of the flasher will depend on the manufacturer. A good parts man should be able to advise you as to a flasher that will work with your plan.

Good luck with your project.

Ray you are right. I have no up front directional light hookup as it is now. When I get fog lights they will serve as the directional lights on the front I should just be able to splice into the left and right wires at the firewall for the front left and right directionals.

I took your advice and the parts store hooked me up with a flasher that not only uses less resistance but it does not recognize a bulb burned out. The pilot and flasher will keep flashing with a burned out bulb. I will have to check frequently to see if the bulbs are still good though. It will be like driving a rig for a company, "do a walk around befor leaving the yard."

Thanks for the help. I enjoy reading the advice you give here on VCCA. Keep up the good work it is greatly appreciated ....Riff

Riff,
You said you are using your two filament bulb for brake and signal. Normally the brake and signal lamps share the bright filament in a two filament bulb. Your setup means either your brake or signal is going to be at a lower candle power like the tail lamps would normally be. If you use the low power filament for brakes, they may not stand out much when they come on. If you use the low power filament for signals they will not overpower the brake filament to let those behind you know what you are doing. I would use the two filament lamp for tail and stop and your extra lamp for signal. This would do a better job of getting the message out to those behind you. Just my opinion.
