E30/E24 US Ellipsoid headlight adjustment knob

Headlight adjustment knob for US Ellipsoids in E30 / E24. Mates with PN 63121385397.

This is meant to be used as a tool and not left installed permanently. 

Note: I've only tested this on my US 1990 325i E30 Coupe. I have not tested the clearance with other years or models.
