Hack - that helped... except they weren't new lights, but old ones from last year... so I had to pass in the Attic.Container(contentType.Decorations) to the constructor... bleh... now some work, some dont...
Need to test the bulbs to see which one is busted....
Code:
For Each Light as C7Bulb In Strand.Lights
    If not Light.Works Then
        Strand.Lights.Swap(Light, new Light(colorRandom))
    End If
Next
