Description

When my dad was getting into his BMW 335i not too long ago, his knee hit the headlight knob and broke it. It turns out that the part of the knob that is keyed to the switch is notoriously weak.

He ordered a replacement but it was going to take a month + to get it from a third party seller on amazon and so we drew this up.

It's a direct replacement for the normal knob. The hex is keyed so you'll be able to have the knob oriented in the same way as the factory one, and it has the tail so that it won't let you rotate it further than you're supposed to.



**Here's the fitment info from the amazon knob:**
