Just buy a set of the euro H4's, Make sure and install relays.
Caution: You're about to enter the nerd zone....
It depends on whether it's important to you to be correct or not. Since it has sugar scoops it was a U.S. delivered car with the sealed beams which are the only headlamps that are correct for your car strictly speaking. You can fudge a bit with Bosch H1's as they were available at the time. You can also fudge with the reflector based lamps with incandescent bulbs standard on RoW delivered cars. H4's are totally incorrect as they weren't introduced until 1972.
There's also a mid-ground solution - the reflector based Euro headlights. You can use H4 bulbs with P45t bases when you want maximum brightness (essentially making them H4's) and replace the H4's with incandescent bulbs when you care about correctness. Of course then you should replace your turn signals with those with Euro lenses as would be correct for a RoW car.
If correctness is not an issue I agree that H4's are the best solution. They look good, have good performance, and are relatively inexpensive, at least compared to H1's.

Here's my best attempt at which headlights were standard when:
Year Covered Sealed Beams Sugar Scoops Euro Tungsten P45t H1s H4s 1965-1967 USA 911-912 non USA 911-912 1968 USA 911-912 non USA 911-912
except 911S after
Coupé 1180226 &
Targa 1185065non USA 911S after
Coupé 1180226 &
Targa 11850651969 USA 911-912 non USA 912 non USA 911 1970-1971 USA 911 non USA 911 1972-1989 USA 911, 912E non USA 911
- The H1 lamp was introduced in 1962
- The H2 followed in 1964--it's now obsolete but replacement bulbs are available
- The H3 followed in 1966
- The H4 was released in 1971
- French [covered] P45ts had yellow lenses
- French H1s had yellow lenses
- French H4s had yellow bulbs
- [Covered] Euro Tungsten P45t lenses came in asymmetric for /LL (left hand steering wheel) & symmetric for /RL (right hand steering wheel)
- H1 lenses came in asymmetric for /LL & /RL (left hand steering wheel & right hand steering wheel)
- H4 lenses came in asymmetric for /LL & /RL (left hand steering wheel & right hand steering wheel)
I recently asked my repair shop to replace my
current lights with H4s. They said they put in h4s
but had to reuse the Sugar Scoops. Isn't it possible
to use the narrow trim rings? I simply prefer the look.

Don...
Sugar scoops and true H4 headlights use different assemblies. You can put H4 sealed beam replacement inserts in sugar scoop assemblies but you can't mount the narrow trim rings that are used on H4 assemblies on sugar scoop assemblies.

Back to my statement that Porsche didn't supply asymmetric headlight lenses for RHD cars until the H1s came out.
Even the 911 Parts catalog says /RL cars had a symmetric lens, but I did find a post in a forum at The Samba which gives the headlight markings from the "'64 bosch catalogue (that has both old and 10 digit part no's) fitments from the headlight listing, lenses from the corresponding headlight spare parts listing.
Porsche rhd asymmetrical lense : 1 305 614 025 / LEFE 98 L 18 X"
I would be surprised though if a VW lens wouldn't fit and those are available. Karmann Konnection in England offers one "for 356B & C models" but doesn't list a Porsche part number.
Bosch and Porsche labels for a rhd P45T pre H1 headlight. The lens has the 7045 designation but I switched the lenses to lhd, the other parts are identical between lhd and rhd.
Thanks. I took a closer look and the parts catalog does indeed show 901.631.101.01 as an asymmetric RHD headlight.
The catalog also shows 911.631.112.00 as a symmetric H1 headlight for RHD.
Porsche offered asymmetric RHD lights starting with 356. I had a Bosch set, sold it to GB. I'd be surprised if they did away with it for the 911/912, since they would not be allowed to sell them in RHD markets.
@ Don - if you don't mind the H1 vs H4 issue, here is what you need. http://www.sierramadrecollection.com...86-p20045.html. they bolt right in.
