The switches on both collectives are reproduced as a ON-OFF-ON instead of a momentary (ON)-OFF-(ON), to direct the landing light beam vertically.

Line number: 635 (for pilot) and 639 (for copilot)
Old line only for pilot (actually I rebuilt taking the copilot line as example, so it may differ):
elements["LDG-LT-2-1-PTR"] = default_3_position_tumb(_("Landing Light Control Switch , EXT/OFF/RETR"), devices.NAVLIGHT_SYSTEM, device_commands.Button_7, 205, true, true)
Corrected lines:
PILOT line 635
elements["LDG-LT-2-1-PTR"] = default_springloaded_3pos_switch(_("Landing Light Control Switch, EXT/OFF/RETR"), devices.NAVLIGHT_SYSTEM, device_commands.Button_7, device_commands.Button_7, -1, 0, 1, 205)
COPILOT line 639
elements["LDG-LT-2-2-PTR"] = default_springloaded_3pos_switch(_("Landing Light Control Switch Copilot, EXT/OFF/RETR"), devices.NAVLIGHT_SYSTEM, device_commands.Button_36, device_commands.Button_36, -1, 0, 1, 212)
