I've recently bought some machines, both snack and soda. I don't know the history on them but several of them have the lights gone and need repaired or replaced completely. As I'm going through them several are missing one or both of the sockets others look burnt and I'm very doubtful that they work. All of the drink machines are Dixie Narco, some are old single price machines with a few 501Es as well. Snack machines are all over the place, mostly Polyvend and USI. Can someone walk me through the quickest easiest way to add lights to these machines. LEDs or fluorescent, I really have no preference. I've got about 20 machines that need repaired and some are older so cost is the main concern.
