There are many companies that will give fire departments discount prices. I would start with http://wholesalefireequipment.com/ as they have a huge selection and wholesale prices.
At the site Project Responder, http://www.projectresponder.com/, there are plenty of lights and supplies for volunteer or other first response units' vehicles. Lights are sorted by type and color, and mounts and switchboxes are also sold there.
Here are some fire trucks for sale: http://firetrucksplus.com/. You can also check Craigslist or ask your fire station what they do with the old trucks when they get new ones.

Yes. There is nothing in the law that says police must have their lights on on the side of the road. Think of it as parked car, do you need lights on when you park your car on the street in front of your house? Even if you do, most states have laws that exempt emergency vehicles from such laws, ie police cars, fire trucks.
You can find toy fire trucks at most stores that sell toys and most hobby stores as well. If you are looking for collector's toy trucks then checking out local antique shops will be your best option.
Every vehicle has the ability to turn on flashing lights. Most commonly, police cars, ambulances and fire trucks employ flashing lights as a warning to other drivers of an emergency.
