Mine only worked when it wanted to also. I called the number on the light & was going to order new mounting receptacles for the lights (they are only 1$ each from stan sloan bait co.) But before I placed the order I cleaned the pins on the bulbs with some scotch-brite & bent the contacts out a little (to make better connection). Works perfectly now. Don't know if it will help, but it may be worth a try.
