I noticed my headlights were flickering every once in a while. So I decided to chekc it out and noticed the female plug was melted inside. I know this can happen with high wattage bulbs, but I they are just stock. Is this a plug and play replacement or is some serious splicing going to need to be done. Any info would help thanks.

Most parts stores should sell a replacement 9007 plug with wire pigtails. No way to "plug and play" since you have to cut off the damaged connectors and splice in the replacments.
This usually does not happen with stock bulbs, are they OEMs or something else?
