Dual filament signal to a single filament ?

[chillinfellow]

Have a 78 kz 400, (b1) I had ordered some new turn signals totally spaced out that the fronts were a dual filament not a single filament like the rears, would prefer to still be able to have them function as a dual, I know I could use them as turn signal only but would like the running lights on too if possible. Did some digging and found a few folks that have done the attached diagram/s and wondering if this would work on this bike ? the lights I had bought ARE NOT LED they are a generic single filament socket & bulb, I did explore looking to change out the socket & bulbs for a dual but could not find anything small enough to fit in the housing, they are a smaller bullet style. Not looking to make this overly complicated, worst case I will find others to use, but like the styling of the ones I just bought, which are not available in a dual. Your Input and suggestions / confirmations appreciated.

I don't understand? Don't you have a local Pep Boys or Napa in the area? Bulbs are cheap....Or are you talking the complete blinker mechanism?

 

[chillinfellow]

Have both Pep & Napa in area, yes complete

I can't see how the indicators would flash when the running lights are on if you use those diagrams.

There are 2 inputs and one ground so works fine

 

[hillsy]

The 2 inputs are joined together after the diodes.

:-[ I only just noticed ;D
Using different resistors with diodes should work but I would just get dual filament bulbs or LED, just so much easier

Dual filament bulbs aren't going to do you any good if the turn signal sockets are engineered with only 1 positive terminal.

I'd personally skip the complications and not worry about the running light aspect of it. I can appreciate the idea if you've got frying pan sized signals like I had on my stock 1976 CB550F, which functioned as running lights, but if your new signals are small discrete lights, they're not going to make you much more visible anyhow.

If visibility is a concern, wear a high-viz yellow helmet and jacket.

I wear a yellow and black jacket ;D
In nature, it's a danger sign

You can make a circuit like the one in the picture but omit the diode in the flasher circuit. Keep the diode in the running circuit, as the diode has a natural voltage drop of 0,7-0,8 volts. Maybe that is enough to make a dim running light, if not, you have to add a resistor in the running light circuit. Make sure both the diode and the resistor can handle the current to the bulb. Tip: the resistor can be another bulb....
