Relaying dim-dip headlights - Type 44

    Excellent stuff. I knew someone must have come across this before.

     Now I know to try hunting for a red relay first. Did you notice the
very interesting way that the solenoid circuit works for that relay?, seems
its earthed thru the main beam filaments!

    I'm quite possibly just going to accept the disablement of dim-dip,
meaning full dip on the sidelight position with ignition on. But I reckon
that it would be possible to disconnect the end of the resistance wire from
the existing low beam feed and connect it into the new low beam feed
downstream of the relay. After all its already been relayed once.

    Now if only I could find where the resistance wire is located on the
type 44 ......
