Notepad is not good.  Better to use a "programmers editor" or at least
a line-based editor.  I think Wordpad will do it.

You want to look for paragraphs like this, beginning with shaderNodeParm:

        shaderNodeParm headlight_PoserSurface_6
            {
            name headlights
            initValue 0
            hidden 0
            forceLimits 1
            min 0
            max 1
            trackingScale 0.01
            keys
                {
                static  0
                k  0  0
                }
            interpStyleLocked 0
            }

Delete everything from the shaderNodeParm line to the bottom bracket
of the paragraph.  (You may have to count the ins and outs of the brackets
to be sure, if the paragraph isn't obvious.)
