Gotta replace the entire light fixture, cord and all. Be sure to get a light that will fit the existing niche. Also, make sure the existing conduit is large enough for the new cord. Most 12 volt lights use a much larger size cord. Finally, install a 120 volt to 12 volt transformer in the supply side of the new light. Lot of hassle for no apparent reason.How do I change a pool light from 120 volt to 12 volts?120 volt would probably be much easyer to use
it is way more common
