This is the story behind the picture:

Something happened to a part of my 1987 RX-7. It’s just above the signal light & just below the headlight. I’m not sure what it’s called, but I took a picture of it (passenger side) broken out & another picture of the driver’s side one (still good). Whatever happened now the passenger headlight doesn’t go up. Can someone tell me what it’s called & where I can get another one? I’ll try to attach a picture here.

 

You're missing the "flash to pass" lens. It's just a plastic lens, there is no mechanism involved and it's not connected to the headlight in any way.

 

The missing FTP lens shouldn't stop the headlight from going up or down though. Looks like you have two issues. 1. Your missing the FTP lens. 2. Your headlight motor isn't working properly. The issues aren't connected. I recommend testing the headlight motor.

 

lens is FB01-51-360B for the right, and FB01-51-370B for the left
