Hi Matt,

Merry Christmas, neighbor. The annoyance is just that and not a sign of impending lighting failure.

The turn signal / hazard issue is most likely separate and fixed by either spinning fuses or replacing the turn signal relay by your right knee.

The bulb failure warning circuit only monitors rear running lights, brake lights, and low-beam headlights. It has no involvement with front running lamps or directional lamps except where your tail lamp assembly shares the ground wire from the long ground strip to the chassis.

That ground could be the issue, but you cleaned it. More likely you have a problem right in the plastic bulb holder with the contacts that ground the shell of the dual-filament bulb base. You owe yourself the confidence a new set of brake lamp bulbs will give you.

Two questions you can answer without venturing out in the cold: (1) is the tail lamp assembly aftermarket, and (2) do you have trailer lighting wiring? The aftermarket assemblies use inferior metal plating on both the housing contact strips and the bulb holders. Trailer lighting means more chances for connections gone poor.
