These round led lights are in 2 pieces. The outer chrome plastic ring needs to be pried off. Carefully cut around the outer edge to cut through the seal. Then use a plastic type scraper or putty knife to pry the ring off. The base of the light should be secured by 3 square headed screws. Should pry off after removing the 3 screws. The light base should have butyl putty around it to seal out water.
