I bought blue halogen bulbs for my 07 dodge half ton. both worked for 2 weeks, then passenger side quit, had 12 volts so i took that bulb back and got a new one. the new bulb worked for 2 days. then i noticed my head lamp socket had a worn out connection point. the center port (black wire) was melted. i then replaced the lamp socket. both lights worked for 5 days, then the drivers side lamp socket also has that middle port in the socket melted. bulbs are fine (with a little burn circle around the male port on the middle prong on the bulb), still getting my 12 volts at the socket but the middle port is melted so poor connection. any idea why this is happening guys? bulbs? wiring harness? PCM? any suggestions would be appreciated/ thanks.

 

I would assume you have a bad or weak connection between the two contacts. That would cause a higher amp load or more resistance and cause heat. Just for chits and giggles, did you try going back to the OEM headlight bulbs since you didnt have these issues until you switched bulbs

 

so i found out that it was the bulbs. they were rated for the same wattage as my stock bulbs and were stock H-13's. But i guess they just produced more heat and burnt out my 2 40$ lamp holder sockets. went through 3 bulbs and 2 wiring harness' in less than 4 weeks. just for reference these are the bulbs: Putco pure nito blue 6000K's. I also did some research and found the middle prong that burnt out is the ground.
