Thanks Pat. Any recommended source for a 6-volt HD flasher? Steve

Steve, When I had my '35 3W, approx 4 years ago, I installed new 6-volt fog lamps from Mac's (Unity) and used them as turn signals. I used a N.O.S. 7-wire turn-signal switch (with rubber cancelling wheel). You will need a heavy duty flasher. That is the long one. It will accept more resistance than the shorter one. The heavy duty flasher allows the bulb to blink at a good pace, whereas with the shorter version flasher, the lamp blinked too fast. I am about to add turn-signals to my '40 Conv. Good luck. Pat

My '34 pickup has only 1 tail light so I suppose I could wire it for left turn signals only. Seriously, what bulbs are in the fog lights? That will tell me what kind of sockets are in the cans. From there we can find a 6 volt bulb that will work in the socket. I did a quick Google search and found 6 volt flashers available. Also found 6 volt bulbs with a power dissipation of 18 watts. That computes to a current of 3.33 amps with a 6 volt supply. The resistance of the bulb in a DC circuit would be about 1.8 ohms. The sockets are the key because your fog light wiring is already sized to handle the load of the higher wattage bulb.

Steves46 One of the great things about this forum is that sooner or later someone will ask a question that I want an answer to. I have a 38 that I have wired a turn signal circuit separate from the original harness. I have the fog lights, and my plan was like yours to use them as turn signals. My plan is to use smaller bulbs, as the flasher (which relies upon resistance to determine the flashing rate), prolly wouldn't work with the high-amp fog bulbs. So....I was going to simply replace them with smaller bulbs. What say the "electrical experts"?

I have a nice set of Ford script 6-volt fog lights on my 46 Coupe and would like to use them to function as front turn signals. Can this be done or will the amperage be too much? I am running stock 6-volt system. Thanks and by the way, I replaced my tired starter with a rebuilt unit that I purchased from Vern Davidson (great fellow to deal with). Boy, what a difference! You would swear that I was running a 12 volt system. Appreciate any info on the fog lights.
