-unless that is an optical illusion, making the low beams look larger than they are meant to be- I've never seen that on a European E24 before. They are the correct buckets, but I think someone has modified/bodged that, using low beam units from another model (E28?) maybe?
In your photo above that is the RH headlight; the low beams are meant to be on the outside and the high beams are on the inside. You should (unless they have been swapped about somehow) have odd low beams, the lamps in the high beam positions look original type (*).
ETK lists four different headlight sets, changing 5/82, 9/86, 7/87. What is the production date of your car?
They all have same sized high and low beam units (with single filament H1 bulbs in them, plus a small sidelight in the low beams) , and the E24 headlight wiper assembly (which is unique to the E24) won't work with different sized lamp units to that. Both headlights need to have a chrome edge ring with 'parking tabs' on it for the wiper blade, too.
BTW the headlight wiper setup changes in 5/82 but the change is (I think) confined to the type of connector plug on the motor unit. The buckets are different at that date too but if they take the wiper unit (not all will) they will accept the same wiper unit to 6/87.
I think the low beam units and the high beam units are not 'handed' in pre 5/82 cars (so LHD and RHD use different low beams, but left and right on the same car are the same and the same high beam is used everywhere in Europe apart from France ) but in later versions the left and right side are different on the same car, because (I think) the mounting tabs are 'handed' on each reflector unit. Thus for 82-87 high beams (which have a symmetric beam shape), there are (excepting France) only two part numbers; one fits to the right side of the car and one fits to the left side of the car (because of the mounting tabs), whether the car is LHD or RHD. Looking at the ETK, this simple piece of information is presented in the most tortuous way possible, I'm not surprised you are confused...
BTW it seems likely that to fit a larger headlight unit to your car, the plastic headlight surround pieces would have had to be modified (cut away) too.
Hella make lots (and lots) of headlights BTW.
(*) both units in the photo above have arrows on the glass; this normally indicates that they are low beam units, not high beam units, because only low beams lenses/reflectors are handed. Is it possible that someone has installed the original low beams in the high beam position? If so the car may not be legal if you only have the inboard units lit up on the dip beam setting.
cheers
