Headlight Control by Start Switch

[DEcosse]

OK - I get what you mean now - a wig-wag circuit for the headlights.
You could probably do that fairly easily with just a flasher circuit using a 555 timer driving the headlight relays. But yes, could do through a PIC also.
Not something that I think would really have much broad market appeal though, so I don't see much return on the design effort unfortunately

Thanks, I know what to do now. Just though a wigwag circuit was what that young lady did as she walked around the block. I crack myself up.

You mean hazard flashers?
Those would be unrelated to either the KeyLess or the headlight Bypass but it's REALLY easy to do - the info is a freebie for you guys.
All you need is a switch of your own choosing and a couple of diodes.
- if you get something in a switch that is really miniature you can possibly mount it directly on your OEM switch housing and the diodes inside - but it's OK to go with an external switch if you prefer (easier to execute)
The switch needs to be a regular switch, not momentary one.

So just three components - 2 x 3A diodes and a switch; note my schematic shows the connections on the main harness side of the bar-switch connector, but these can be made on the bar-switch side or even inside the switch housing.
For those who like numbers, each diode will be supplying front& rear light on one side - total 20W - that is ~ 1.7A, so 3A diode is well safe.

DEcosse...you come up,with some pretty cool stuff. I see you are showing a flasher module on your diagram and as near as I can tell this is something the Rocket 3 Touring does not have. The turn signal flashing appears to be controlled by the ECU. I assume if you wanted to do this on the Rocket you would need to add a flasher relay. Although thinking it about now, the flasher circuit may be functional with the ignition switch in the Parking Light position. I'll need to check that out. In that case no other flasher would be required.

The flasher module is integrated into the Instrument panel on the Touring - but the mod is executed identically on the Touring.

I'd check your local laws before doing the wig-wag headlights.
Some jurisdictions restrict this to police vehicles.

Good point. You may have saved me from my self. I'll check it out.

Back to the original theme re the start-switch operated lighting control - this would be a simple retro to late model Roadsters that already have the additional OEM relay for headlight circuit.
i.e. no complete EB or DEcosse headlight relay (key-switch bypass) kit required to get this capability - can be installed stand-alone on those models.
