Hey everyone,

I was wondering if anyone knew what this yellow wire coming from my headlight is? It's on my 1983 W123.



It's clearly an aftermarket installation, as someone has drilled a little whole for the wire in the headlight casing. The wire goes out from the headlight main bean wiring to the black box on the inner wing. Any ideas?

Also, is it likely that I could remove it without screwing anything up?

I want to say it's for an alarm system on my car, but there's no alarm active on it, so perhaps it's defunct wiring.

Thanks!
