Does the highmount brakelite work? If not, check voltage feed to and from brake switch, use a voltage tester. Orange wire is hot all the time, feed to brake switch. White wire goes hot when brake switch is activated, voltage for brake lites.

If the highmount brake lite works and the lower ones don't, I check the feed from the multifunction switch.
