Check for a bad ground circuit. At the taillights ensure all wiring are secure. You might need a test light or Digital Volt Meter to perform test.

The link explains how to use the DVOM. A test light is similar in usage.

Test the wiring at the light. The light itself is likely bad.

MY BESTUS BUDDY HAS A 2000, TAIL LIGHT/ TURN SIGNAL ISSUES.

THE BULB HOLDERS TWIST INTO THE FIXTURE ON THE REAR LIGHTS.

WE DID SOME SWAPPING AROUND OF "TWISTY HOLDERS" AND FOUND THAT THE SMALL CONTACT ON THE HOLDER HAD TO BE BENT OUT A LITTLE MORE (LITTLE COPPER TAB DEALEES), AND THE THREE CIRCULAR ARRANGED CONTACTS ON THE FIXTURE, HAD TO BE SLIGHTLY SANDED OR SCRAPED CLEAN WITH A KNIFE BLADE, TO CLEAN 'EM UP---JUST FOR "INSURANCE", WE APPLIED A THIN DAB OF DIELECTRIC GREASE ON ALL CONTACT SURFACES (AVAILABLE AT A PARTS STORE)

ALL SEEMS GOOD NOW, HE USUALLY FINDS ME WHEN SOMETHING AIN'T WORKING RIGHT!

LET US KNOW HOW IT GOES
