|

Does anyone have a diagram, or link to one, for adding flashing indicators to a semaphore system? _________________ Alistair

The simplest way is to use two flasher units. One for each side. Wire the left side semaphore to one and the right side to the other. If you want a warning lamp too the wire a small lamp across the two flasher outputs.

If you would like to keep your original semaphores working at the same time then another moderately simple way uses a single flasher unit, plus two ordinary 12V relays with a single set of contacts.
Each relay's coil connects to one of the original semaphore circuits so that one energises when you turn left and the other when you turn right. Both relays' contacts are fed from the output of the flasher unit, and the output from each contact goes to the left or right side flashing indicators. Any convenient fused supply feeds the input of the flasher unit.
This system has the advantage that it can be extended to provide hazard flashers by adding a double-pole relay, energised from a dashboard switch. |

Glenn,
Thanks for the reply. My car has semaphores and flashing indicators...I was looking for a diagram to send to someone who wanted to do it in Canada. A picture is worth a thousand words...or just my laziness to create my own!
I have actually found one from Autosparks web site and have forwarded it to him.
Thanks for the info... maybe I should have explained better!! _________________ Alistair
