Saving the old lights

What do you do when the old wiring in your building can’t handle 120 volts? Our electrician had a brilliant suggestion: convert the power to 12 volts (the equivalent of car batteries) and get RV light bulbs. Thanks to his suggestion, we were able to save all the old lights in the retail area of our building. We’d like to preserve as many original features as possible, and we’re happy when we find ways to do so.
