Dimmed high beam as DRL?

[Ot_tO]

You mean with *pulse width modulation* (PWM)?

Which countries have this dimmed high beam as DRL?

(Which countries have dimmed low beam as DRL? At which %?)

I read, the bulb should run at least with 76 % of max brightness.
If not, it will reduce the life of the bulb, because it need certain amount of heat for the regeneration.
This could be correct?

How are the experiences of the owner of such cars with dimmed low/high beam as DRL?
You need every few months new bulbs?

Thanks.
