I searched the forum first before asking, but the rear parking lights, brake lights, turn signal lights and reverse lights are driving me nuts. They constantly go out, but the connection is what goes bad, not the bulbs themselves. I have cleaned the terminals, even replaced both bulb receptacles and eventually, they start going out and I have to jiggle the connections again and they last about a month. Any thoughts as to what would work to get a better connection back there?

Thanks
