If you come up with a working model, let me know. I work in the service department at an RV dealer, and we could market them as an option.

If your driving with headlights and running lights on (2 oclock position) and you switch to any other position your headlights go out.

So in order to flash the running lights you would have to go from 2 oclock to 12 oclock and back to 2 oclock , consequently flashing your headlights and running lights


I thought the OBS trucks were essentially the same operation:
position "0" (knob all the way in) - all lights off
position "1" (knob pulled one click out) running lights on, headlights off
position "2" (knob pulled two clicks out) running lights and headlights on

therefore you would also have to flash your headlights in order to flash your running lights....


(Im talking about driving at night, when you have your headlights and running lights on. Hence why I am saying you cannot flash your running lights independent of your headlights)
NOW YOU tell me that it's NIGHT TIME that you want to do this...I don't pull my trailer at night so....
 
So if you turn your dial to the 1o'clock position, you can't turn it back to 11 or12 o'clock without going to 2 o'clock first? I have the old pull knob with detents.

Doesn't the headlight switch have two positions? Mine does, so I don't have to cycle the headlamps.

I have found that the people who take the time to give you an all clear to move over, understand pretty much any thing as a thank-you.

Since you have to move your hand and flip a switch, why not just use the headlight switch? Maybe it's just me, but it seems like you could use the up fitter switches for something more important, since the ability to cycle your marker lights is "built in". I use the brake control or headlight switch myself.
