Last night my left headlight became dim. It is now yellow instead of white like the other. I checked the connections & found that the cord that plug into the back of the headlight is almost melted looking. Will this be something I can easily fix? I'm attaching a photo of the plug thing. Sorry I don't know any technical names. This is my first jeep & also first vehicle that isnt a sports car. I would be so grateful for any tips or advice y'all could give me. TIA
