Thank you all for your comments.
So I bought the new bulbs and installed them yesterday. So far so good! I will keep you all posted. I can tell you - They are bright!
It was dark yesterday when I installed the bulbs so I didn't notice the cables going to the tail lights. Are they visible or easy to access so that I can check them every now and then at the beginning to see if there are any visible signs of heat at the wire harness?? Do you know what area the cables have??
