My passenger side low beam headlight has an electrical problem?? We have had to change the light blub 4 times in 1 year. The connection is over-heating and melting. Got a new plug and it did not help. Any suggestions?

Check voltage AND grounds for proper current/voltage (power side) and resistance(ground side) power should be within a tenth of a volt of battery voltage (generalized) and ground should be near zero ohms.High resistance (ground side) or lower than expected voltage(power side) can both cause early failure of any electrical item.
