I'm not sure of their function yet, but there are a heckuva lot of relays in this box. Lamps make sense.

Here's the link to some documentation on eBay:

No idea if those are complete or not, or if they include wiring diagrams. And $30 seems a bit much for a guy to run off another copy of his .pdf of the docs. $1/page!
