Convert E30’s headlight into both high beam and low beam?

[Sillea]

Aloha everyone from Hawaii!
Thanks for all the great forums and I apologize if this has been discussed but I just spent an hour trying to find the answer to this and couldnt find it.
Anyway I am wanting to run the high beam delete intake (I know it’s not a power upgrade just a looks/sound preference so please let’s stick to how to make the high low beam work) and would like to make the low beam on the side I delete also work as a high beam. I assume I would need to get a new headlight for like a Jeep from amazon or something that has the dual function built in but as far as parts and wiring what else would I need to do this?
Is this even possible?
I would prefer to just modify the one side and keep the other side stock if possible as well 😅
If so how can I do this.
Thank you!🤙🏼

I guess you don't have sealed-beam headlights.

The sealed outer headlights already combine low and high beams.
You can improve them by buying a replacement H4 Hella lights. https://www.bimmerworld.com/Lighting...Kit-71456.html

So, the easiest factory way is to install the sealed-beam frame.
