Taillight issue resolved

Put in a new led third brake light and new smoke lensed clear taillights. Right parking light and left brake stopped working. I unhooked my trailer light hook up thinking that was the problem. Then I put the old third brake light back in, didn’t work. The fix was putting the old taillight assembly back in with the new smoked lenses. The only thing I can figure is the oem assemblies had metal sockets and the new ones were all plastic. Anyhoo it works now so awesome
