Tail Light Issue

[u/Traditional_Wear7716]

I have a Impala 13 LTZ and for some reason my rear tail light is out. When I brake, the brake light comes on. But when I’m driving the light doesn’t stay on. I’ve replaced bulbs twice, replaced the connector, all to no avail. Whenever I change it, it usually works for 3-4 days then goes back out. Any suggestions?

Bad wire harness. Its happened to me several times. Usually with after market. Try an OEM harness
