Usually it's Left=Acc/Center=off/1 click right=run/right=run and lights.

1 click right=run/right=run and lights.

And to expand - on some bikes, there is no difference between these two positions.  I.e., run also turns the lights on.  Originally that may have been done due to laws in various countries.  This was accomplished by a "bridge" between circuit breakers.  It is easy to modify to be able to start without the lights by removing that "bridge".

Your trike may very well have custom wiring and components, so who knows how it is wired up?

I think there are a few reasons for the two run positions. The one with lights off is probably to help starting, less draw from the light on the battery. Batteries weren't as strong back then.
Another reason is less draw on the charging system so it can recharge the battery easier.
And the third, as mentioned, was no daytime headlight laws.

And number four, if your charging system takes a dump, can get farther on "IGN" and no lights on just the battery...

DOT forced HD to put the bridge between Ign and Ign/Lights.  Because the Gov decided bikes need to run with a headlight on cuz its safer.   Which I would agree with... but with crappy little battery you really need to be able to start without the additional light load.

Yes there are several reasons why there were two positions (run vs. run+lights), but I meant (I think) the reason they short-circuited the two positions were due to laws requiring lights to always be on in many/most jurisdictions.

We had one guy in the neighborhood who really had no business riding a motorcycle, much less an old Shovel. If I had a dollar for every time I had to try and push start that POS, I could have paid for one hell of a bar tab. It really was comical how many times that thing didn't start. Push starting was no guarantee. 50-50 at best.

I hope you had the sense to make that dude push YOU on his bike to get it started.  ;-)

I don't really do factory bikes but I have always wired mine up to be able to start and run without lights for all the reasons pointed out in the above posts. I installed a later model 3 position switch a while back (replacing my old shovel 4 position switch) and the way I wired it center was off, left was ign. without lights, and right was ignition with lights. The problem was you couldn't start it on the left side and then turn on the lights without killing the motor. I ended up installing a relay for the lights powered by the starter relay. Now if you start it while the lights are on it automatically kills the lights until the start button is released.

Today i will be changing out my H-D battery date  6/07 on my sporty . starting to give a couple clicks in  am when cold. That and my 03 bagger both have a separate on/off switch for the high beam . starting rocker is on high (no light)  bike running rocker goes too low beam. High beam flip the switch at night if needed. Batteries last me yrs longer .A lot easier than changing out to a different ign. switch.

Sometimes on the 76 I forget to turn it all the way to -LIGHTS-  after I start it. Usually that moment comes a few miles down the road.   Then sometimes I forget to cut the throttle when I reach down and flip it to - LIGHTS-. Usually that's followed by a loud bang.
