Of course you should ask! Save whatever you can. Try your best to get them.
It's like me saying this, "Should I save some mercury lamps and ballasts from the mercury vapor underpass lights that are soon to be removed?" (actually about to happen here, by the way because of a big improvement project going on).
Well, If I catch them with the bucket truck, I'll try to pull over on the side of the freeway and I'll ask.

I'm probably leaning more towards the intersection ones, which they have multi-volt ballasts and the freeway ones are 240/480v ballasts. But I'll probably might change the ballast on the 240/480v ones, or get a dryer plug to run the 240/480v fixture from 240v.
