AE86 Headlight + wiper wiring (levin)

[Ivan141]

Looks like a coil to me, although I'd say it's not actually a loose component but wound from the wire itself.
If it's only the shielding that's gone brittle, clean it off and paint it with plastidip. If you want to replace the
wire, count the number of windings and unwind then rewind the coil with new wire, but I'd advise against it.
