Aircraft's panel problem:
First be aware that some panel don't have the required button separated
(strobe, landing light and beacon) Some panel have two lights connected
to one button (strobe and beacon for example) And last some use their
own system not connected to Fs2004 value (as PMDG for example)

if you have one of the above case disable the light penalty in FsPassengers
to fly those aircraft or edit the panel.cfg to replace with the correct button.

It's a 737NG (The PMDG NGX).
It has a 3 positions switch:

UP = Strobe and Steady
Center = Off
Down = Steady

I set it to Steady for taxi, Strobe and Steady for takeoff and back to Steady while leaving the runway where I landed.
Am I doing it wrong?

Thanks.
