    Hi, bergoff.

    That is a cool headlight. I've been wanting to upgrade as well, original 42 yr old bulb gotta blow soon.
    Long time ago I built a daylight sensor that controlled dome light delay in my hotrod.

    So, what about a daylight sensor to control the halo ring?
    You have enuff room for that 4" depth?

    PS...
    Here in TX, headlights must be on at all times (only if newer than `74, I'm excused)
    If it were down here, I'd probably use a simple relay, halo ON unless H4 ON, then halo OFF.

    Use a latching relay that operates and latches the first time you select Hi beam.

    Well, here is a possible wiring diagram using a DPDT 12 Volt relay:

    1. When you first turn on the headlights switch, the +12 goes through contacts A to B to power the Hallo.
    2. The first time you select Hi Beam, the +12 goes through the diode to the coil of the relay and powers the relay which switches contact A from the Hallo to the low beam filament of the H4.
    3. Contacts D and E close to provide power to the relay coil so it will stay energized.

    Thanks Pete that makes sense. I should be able to figure that out.
