My van is pre 1960, and I can legally use all red indicators, my issue is I only have one smallstop/ tail light per side, and I do have a plan,  what I need to know is what resistor do I need to run in line to trigger a 2 pin flasher with ONE normal incandescent bulb, I'm guessing a pair of 15 ohm, 10 watt resistors in Paralell would probably do, but I would like a bit of confirmation. |

you will need to so some serious rewiring, American cars have complicated turn signal switches which have the stop lights running through them, so they have 2 inputs and 4 separate outputs. you could probably make a conversion circuit with a couple of relays.

I have something like that planned, I can make a 4 relay system that should duplicate something like that, or if I can find a Lucas DB 10 flasher relay from a Morris Minor MM series that will do exactly what I need, it playing on my mind as I'm Laying out the wiring thru the van at the moment. I did somthing similar on a MK1 zodiac many years ago, |

Are you thinking of something like this sort of arrangement for the rear lights?  If so, the ballast resistors can each be 10ohm 20W (or a pair of 18ohm 10W in parallel). What will you do for the front signals though? I was able to put a second bulb holder for a 21W silvered orange bulb behind the existing white lens on mine. |

Instead of using a flasher relay why not use one of these to trigger one relay (capable of switching the required current) no need for ballast resistors and with correctly rated relay additional lamps (front) could be added. The built in relay is rated at 10A.  Linky |

Thank you gentlemen, Clamity, that very similar to how I did it before, I I have started thinking along lines of using a shared feed between from and rear indicators on a relay(NO) switched by the stalk, that could run both front and rear indicators on a 2pin flasher, providing I run one for each side, the only down side of doing this is it gets relay heavy if I insist on using automotive relays, at the moment I cant find any double pole NC relays, otherwise I will need 6 relays and 2 flashers. Jimi, I never considered something like that,indipendant flashing load bearing SSRs, a bit of research is coming today |

This can be done with 2 double pole relays, fronts included. Look at Vehicle Wiring Products for relays.
My last rod was done like this as is my pickup.
Finishing breaky at the moment, I'll put a drawing up in a bit.
All assuming that I've understood the question!
Edit. My memory is not up to scratch. I used small industrial relays that were double pole change over relays.
I got them from RS Components.
Is a drawing of interest?

The problem i can see with that diagram Calamity is... there is nowhere to connect the front indicators.

Here's how I did it. The first drawing is from about 30 years ago when I sat down and worked it out (nowhere to look it up then) hence the scribbled out bits.  Then the same in a different way when I did my pickup.  On my pickup I used some relays from Schneider (and bases). You should be able to get them at a local industrial electrics supplier. |

I have ordered a pair of dual pole NC/NO relays, lets wait and see what turns up, now my thought are rolling along, and I need to power my number plate lights that feed will need to come from the rear running lights, now of course, if I feed from one running light and I indicate the numberplate light will go out, so, if I feed from both bulbs That will cure the problem..... nope, I will get cross feeds from one side or the other, If I fit in line Diodes, one either side of the number plate bulb, that should stop the cross feeds to running lights, what ratings for the diodes would I require??..... thank you chaps, you are helping and inspiring

are the tail lamps not twin filament?

What datman said. Normally a 5w rear light and a 21w brake light. It's the brake light you make flash.

they are twin filament, but as I will cancel both on that side and flash the 21w I would get a back feed from the number plate light and turn on the running light.

Ian, that's not how it's normally done. It's the brake light that flashes.
Why do you want to cancel the side light?
