My ZS is on standard bulbs - whilst not fantastic, I currently find them adequate for my needs. The ZS also has the headlight adjustment wheel that you mention.FYI. The MG5 exclusive does not have auto levelling headlights. They do have adjustable levels from a dial next to the mirror switch, but they’re not the automatically levelling type that you need for aftermarket HID units.
I find the headlights fine, with a standard halogen yellowish colour temperature and the projector lens giving a very sharply defined cutoff.
It is this colour temperature that gives the appearance of being dim, hence some have a preference to change the bulbs to a whiter/bluer colour. It’s personal preference.
Yeah - It’s a problem that is now given to the MOT station to parole instead of the police.They were always illegal, so now the MOT has been updated in alignment.
Strictly speaking LEDs in any "exterior" lamp not designed for LEDs is illegal, but it seems they are only after headlights.

Aftermarket LED Bulbs: MOT Rules And Legalities

LED lamps do suffer from a much shorter life span than the standard OEM lamps.I’ll worry about it in three years..
I hope MG will take all these comments on board and next 2022 EV should have LED’s on. I had to upgrade mine to night breaker ones, yet can’t compare to the BMW LED lights I’m used to over 8 years !!They are definitely not as good as the lights I’ve had in recent years, Xenon & LED but they are adequate. They emit more “yellow” than bright white, as a guide I noticed because of what I’ve been used to (10 years of Mercs) however my wife didn’t, and she drove the other cars. ?
