ok i have a 2002 ram quad cab i have had the lamp out **** and one thing i find out that my headlight will go out with i put the lights on i will turn off turn on and its works ok sometimes the parking light will not work too all on the driver side i have put new boards in taillights and new bulbs all around what could be going on it only happens sometimes mostly int he rain or something likte that

 

Grammar might help a little for us to understand. If it only happens in the rain and no other time,water is getting into the connection causing it to lose continuity. If it happens at other times then it sounds like a loose wire or a dirty connection.
