Title: VIA Rail Siemens Venture Charger - SCV-42 - Lights
Post by: Takapu Road on January 18, 2026, 05:03:08 AM
Hi

On the front of the SCV-42, below the 'headlights' between the ditch lights there is a single light that currently does not light up.

Using JMRI Decoder Pro, where is the appropriate configuration to control this light?

* I believe I am looking for a control on either the "Lights" or "Function Map" pages - possibly a combination of both...?

And/or, what action on the controller activates the light.  (Using NCE equipment)

Any help would be appreciated.

Hi Takapu Road,

This light is the auxillary headlight. It is controlled by entering Light Mode by pressing F8 twice, then pressing F5. It can be toggled on or off when the headlights are at full brightness. When Rule 17 dimming is used, the Aux Headlight will be off.
