I need to add daytime running lights (DRL-s) to my car, and since I have separate high and low beam lights, I thought I could use high beams for DRL-s.
First idea was to connect high beams in series, but since both are grounded I think that I can not do that.

My leatest idea is to use current regulator like this one:
Any thoughts, or better ideas?
Here is the solution for a later BMW model (E36):
