I need to get my car inspected but cant because my third brake light is blown. not sure if i nned to repalce the whole bar or if i can replace just the bulb looks like it is built in but i cant find the piece online anywhere can someone please help!

 

It's called the CHMSL in the manual (Center High Mount Stop Lamp).
Check at the light itself to see if it is geting 12 volts when the other brake lights are on.
If not, check Connector S301, a blue connector in the body wiring harness, located near the driver's left leg.

Let us know what you find.
