Dang that's a good deal! I'd snatch that up, fill the back with water, and haul kids around all day in the summer sun! Nice truck!
Headlights are dirt cheap. Just pick one up for maybe $12 and put it in. If you need to test the lights, just move the one that works over to each of the others and see if it comes on. If it does, wiring's fine!
Also I noticed your username, is this with thoughts of EMP in mind? That's one of the reasons I picked up Cecilia for originally. I want to be able to get work and light traveling done if things get hairy.
