anyone have any idea what the dash indicator light in the bottom most left is for? Looks like rear lights, or brake lights....I recently changed one of my brake lights, and all of my lights work, but the indicator light turns on intermittently

 

it means one or more light is going bad.

 

out of which lights? The tail lights, brake lights, or the upper mounted LED brake light

 

Have someone stand behind the car and test each light until you isolate the problem.
