left tail light has a bad ground. probably coroded. when you use the brakes and the brake light goes on it has no ground so it is grounding throught the turn signal circuit. common jeep problem. Take the left tail light off the Jeep and clean the ground points and use dielectric grease on them before you re install
“He who knows not and knows not that he knows not, he is a fool, shun him.
He who knows not and knows he knows not, he is simple, teach him.
He who knows and knows not he knows, he is asleep, wake him.
But he who knows, and knows he knows, he is wise, follow him.”
