Yes, sorry I have just been browsing and saw your post now. I’ve converted my green line to the Monte Carlo version headlights here in India and faced the same issue.
Its possible to do and headlights them self have an extra cable inside which needs to be connected via relay to the shutter power which will provide the bulb power when you switch to high beams. I’ve done this and explained it here - https://www.team-bhp.com/forum/diy-do-yourself/180348-skoda-fabia-diy-monte-carlo-edition-mods.html
I don’t recall taking pictures of the actual connection and will update his if I find any. Is definitely possible and has been working since.
You can take the connection from the HL connector harness inside the headlight with wire taps or lug connectors soldered in and then use that (power to the solenoid) to power the relay to power the bulb (via a lug connector soldered to the bulb holder).
I had made a harness to do this for both sides with one relay (30A).
Im currently using Xenons (Osram) and they’re good.
Thanks.
