Right turn indicator

Hello all.

I noticed today that my right turn indicator doesn't function when the headlights are on. It always works when the headlights are off, but it doesn't when they're on.

The left works all of the time.

Any suggestions on the possible cause and how to fix it?

Thanks!

Probably a bad ground, follow the black wire.

That, or a bad bulb socket

press in the bulb while the flasher is on ...
