I've incorporated the Radio City Music Hall on my layout.  The building has 2 types of lighting: an internal bulb and marquis lighting.  I've replaced the internal buib with a 12 VDC LED.  The original 3 VDC power adapter feeds the marquis  via a momentary push button switch when activated provides either a flashing marquis or full on illumination.  Inside the switch assembly is a small circuit board.   When the building is turned on, it comes up flashing first and requires a button push for full on illumination.  I only want full on illumination.   Can I provide 3 VDC directly to the marquis and eliminate switch assembly ?  I'm not sure if the marquis is LED or incandescent.  I don't want to inadvertently damage the marquis by eliminating the switch assembly which might provide LED current limiting or voltage change.

Here's some data for those who follow:  The switch assembly circuit board contains the flasher and switching logic.  The output voltage to the marquis is 2.1 VDC for the flasher pulse or full on.  The input voltage is 3.0 VDC so the switch assembly provides a voltage reduction to the marquis.  Based on the above, applying 3.0 VDC directly to the marquis would result in an over voltage condition.
