if the beam pattern has a proper cutoff and few if any hotspots, the number of lamps running doesn't really matter
although there's a potential issue that usually you want your high beams to be more like a flood light, with no cutoff, in order to better illuminate the entire road
Ok so here is the long awaited beam pattern I apologize for taking so long but life has gotten in the way with side projects. 20' back from wall low beam shown. Its a grey building The look with low beams on Here is the High beam pattern. This is how all four look on high beam
I installed the lights as they had been intended from the factory. The new lights do come with a third wire attached to the inner high beam bulb if you would want to use all four for both high and low beam.
I hope this information is helpful to some.
thank you for taking the pics, much appreciated
but that's...not a good beam pattern.
it definitely isn't everywhere, but there's a lot of hot spots and its uneven and the cutoff is rather fuzzy.
for the price it's pretty good but be wary of oncoming drivers for sure

An experiment to possibly improve the beam pattern
clock/rotate the LEDs in the headlights until the blade is aligned vertically, so the chips are facing 9 o clock and 3 o clock.
Apparently that's the "correct" way to face the bulbs, and being even a little out of alignment can have a dramatically negative effect on your beam pattern
I'm confused which ones you ordered? Do you have a link? The description you posted says 24 watts? Do you wihich they were brighter? I'm looking at those same housings but with 40Watt LEDs?
ah, if that's the specific set i now have a better idea why the beam pattern isn't great
the bulbs in that kit are the four sided kind and they actually goof up the beam pattern much more than the two led "blade type" bulbs like this one
notice how the LED chips are sunken in, so the distance between them is super tiny, this best simulates how the filament in a normal halogen bulb is teeny tiny and in the center
this video goes into really good detail on what kind of bulb geometry you want
i just caved today and bought these led bulbs off amazon i've heard good things about.
i also purchased the same lights as OP but with the halogen bulbs a few days ago as just something to up my brightness
those housings + these bulbs positioned just right...i wonder if it'll be the ideal beam?

These are installed in my 1976 Corvette so I don't know if the earlier years (like 68) will be the same.
Ok so I installed one set of headlights and they fit as advertised as OEM. I had to do absolutely NO modifications. When I pulled them out of the box I was not sure because of the way the mounts are on the side of the lights. but the retainers fit perfect with no modifications or longer screws.
These look best to me because they look like a regular replacement light. Showing retaining ring fit on the low beam You can see my old inner high beam bulbs. Aircraft landing lights just low beams in better shot of high beam landing lights The bulb does say made in China Showing headlight protrusion from the bezel
the picture shows the housings are made in china not bulbs unless the bulbs arent replaceable and are part of the whole housing assy? thats the way mine are but mine were also only $25 a housing/bulb with shipping... since these are from china that means they are very likely sold by other vendors rebranding them also and at different price points.
These look like a good alternative too that should fit without mods and will take any of the aftermarket led bulbs designed for the h4 bulb housing but as mentioned you really want the ones that have the leds in the stock postion where the halogen filament would be to get the best light pattern.. I went through a couple sets of led bulbs on my ridgeline (they were only $12-15 a pair so no big loss) till I found a set that worked well in my stock halogen housings last years and actually worked better than stock halogen bulbs. https://www.ebay.com/itm/5-3-4-Round....c100005.m1851

The housing do say made in China and the bulbs do appear to be standard H-4 bulbs. The bulbs are removable but I did not try to install a standard H-4 bulb.
I guess an alternative may be to purchase a set of lights with the halogen bulbs and hope the LED ones will fit. I thought of going that way but figured for the money I would try these to give some feed back to the forum.
I generally don't drive my car a lot at night but it is nice when I did As far as blinding other drivers I did not get the high beams warning shots from other drivers. The very first impression I got driving with them was Holy **** these are bright. The signs on the road lit up and I could actually see things. Yes I was waiting to get the old light flash from other drivers. Now trying to compare these to my daily driver is you cant.
ok so, a comparison shot.
i threw those hikari LEDs into the octane housing that OP used, and the results are interesting
above is halogen, below is LED
annoyingly, there are concentrated hot spots more than the halogens, but the general beam shape is remarkably similar and the cutoff is comparable, although there are some bits in the middle that reach above the cutoff
so, projectors would be superior but this is surprisingly good
I can try to get better pictures of mine from post 22. The photo from post 22 was not the best it could have been, a few things are the car was sitting down hill from the building the building was grey and the air was very heavy with haze in it which I feel distorted it some.

Well you need to stop smoking the tires off the rims before you take pictures pal!!!! lol
ok here are the headlights I installed. I will get you better pictures of the exact cut offs and beam patterns against a better back drop. I can not say whether they are a perfect beam pattern or not but are a much better than stock. Two bulbs per box.
update: got it out of the garage finally
this is the pattern after adjusting the lights a bit so the beams are overlapping properly in the vertical and horizontal
i don't have access to a nice flat wall with 25ft in front of it, which is the proper spec to aim headlights, so i don't have it exactly right yet
but it looks pretty good. No blinding but nice and bright
