Is it safe to use an old lamp without rewiring it?

Often not. Old wiring can become brittle, cracked, or frayed with age, and early cords and sockets were not made to modern standards. Using a lamp with damaged wiring can create a risk of shock or fire. If you see cracked insulation, exposed wire, loose sockets, or a plug without modern features, have it checked before using it.

Rewiring is a common, generally accepted repair for antique lamps and usually does not hurt value much when done carefully. A good lamp repair shop will replace the cord, socket, and plug while keeping original parts that matter, such as distinctive switches or fittings, when they can be preserved safely.

Ask the repairer to save any original parts they remove, so they stay with the lamp. For lamps of significant value, choose someone experienced with antiques who will avoid drilling or altering the base. Electrical codes and safety standards apply, so use a qualified repair shop.
