Here's my opinion , aidanhh :
Most people who buy lamps want to use them as lamps .
High on the list(s) of concerns for rewired/restored electric lamps include -
Is the wiring 'vintage' replacement/restoration hardware , or has an item been rewired with actual 'period' wiring (there's much that can be 'wrong' with period wiring , including asbestos & deteriorated insulation , even if it's vintage wire from an un-used spool) .
Use of the proper gauge of wire & hardware for the application , especially with multi-bulb lamps .
The most important thing , provided that all of the above have been considered about the general condition of a lamp , is wiring the lamp with proper polarity (& using a replacement plug that only can be used in one direction - one wide blade , one 'thinner' blade prong on the plug) .
The problem is that many household 120vac receptacles (in the U.S.) are wired 'backwards' .
Improperly reversing the polarity of an electric lamp can electrify any metal parts of the lamp that are in physical contact with the 'hot' lead (usually the barrel 'socket' of the lamp) .... this could lead to electric shock , or worse .
Simple way to avoid liability would be to explain how the lamp was rewired (properly) & include a disclaimer/statement of non-liabilty for you , the seller .
