Electrical Issue?
 

2016 SD with only 35k miles. Changed my tail light bulb a few weeks ago on passenger side. Today I noticed my driver side was out and changed it as well. Heres what the plugs look like on both sides. Looks burnt? I do run my head lights or parking lights probably about 80-90% of the time. Im guessing it is getting too hot?
Is this normal?
