right rear brake lights / signals out

Hey new bird owner here, working on getting it ready to fly again.

88 bird, right rear brake lights are out, and the right rear turn signals will not flash. the front signals stay on steady. the left side seems to be working normally other than a slow flash. tail lights work normally. don't know if the hazzards work - haven't checked yet.

I'm thinking a flasher, and a MFS....

Or a bad ground.

A DVOM is your best friend. Buy one and use it often....

Or the wrong bulbs.
