Christmas Victorian Streetlight

This is one light from a set of 10 xmas lights, that look like vintage streetlights. (standard 120v series-wired mini lights)
Saw it (still in box) at a thrift-store & thought it was pretty cool looking, so I grabbed it.

They just have a standard incandescent 12v mini bulb inside (not sure how the things come apart to get at it tho) Would be even cooler if they had made all 3 light up, rather than just the center one
If they still made 5mm Cyan LEDs, I'd be tempted to convert this to LED, so it'd look somewhat like MV!
