I'm kinda liking the stock Phillips. I'm a Hella H1 H4 guy on my 62 but here I can see farther in your pictures with the Stock it seems
 
So, in the end ..... to me, the best pattern was the stock lights.

The yellow 100/80 and 130/90....honestly could not tell any difference.

The bright white are good but that’s just a personal thing. Some like white. Some like yellow.
In the end, the stock bulbs went back in. I like the pattern the best.

Mr Kyoto likely spent a few hundred thousand coming to that same decision. I’ll go with him too.
 
Electrical Engineer Wayne Tangen of the 3FE list build a dozen or so harnesses for members more than 15 years ago. We also had a group buy from Susquehanna Motor Sports for Hella Lamps and H1 and H4 bulbs. Wayne's harness is very involved and works great. With 80 W low and 100 W high I put 400 Watts down range on high beam and it looks like an alien abduction is taking place. I have the schematic, parts list, bracket template and instructions. I think I remember he was releasing the design to anyone who wished to commercialize it.

the reason I asked Onur that was the instructions show a 4 light system

I think it might be the Phillips design rather than the wattage. I like the Phillips and Sylvania higher performance bulbs better than
the Hellas but the price reflects that. A Phillips Xtreme vision 55/60 is 22.00+ a pair where the Hella 80/100 is about 12.00.
I think side by side the Phillips may actually be brighter. Same with Sylvania Silver Stars.
This just may be a case where the Phillips is just a better product than the Hella all around

This is really good info and appreciate your sharing of this and research. I agree the stock bulbs from those photos are superior. I will be putting a pair of these in my 60
 
A bit more tech on H4's...

All of these reflector housings are designed for a omnidirectional light source to be installed, ie. a halogen filament. The IFP, the Hella's, the Roundeyes, and the latest Koitos are all designed for a halogen filament bulb. Any other type of bulb, especially an LED bulb, will be sub-optimal for these housings. LED bulbs give off a directional light source and as you can see in @wngrog's photo, and as @lcwizard has pointed out, they don't work right. LED H4 bulbs are a big compromise... a directional light source made brighter to compensate for not being an omnidirectional light source.

There's some great, very exhaustive tech, on H4 lamps over at Tacoma World. The guy who authored that post has a whole series of VERY good tech on headlights.

I've got Hella's in my 40, and the Koito's in my 75... the Koito's are just a bit better. And as @ToyotaMatt has pointed out, they have the classic look the original poster was going for.
 
LEDs were awful in them.

I’m running 24v Bosch units that work very well.

Any way to get a part # for the Bosch 24V to save me looking for them?
 
FYI....I’ll post this both places being discussed. If you have closed light housings and the dopey wire bar on the fender, the plug and play kit is not plug and play. You will have to drill a big hole in your housings or put the relays upstream of all your factory stuff

Edit. See below for another option.

@wngrog , are you talking about the headlight buckets that the headlights go into? Not sure if thats what you meant as the "closed light housings," but I manged to fit mine into my "closed light housings" and they work fine. The only problem i would run into is not being able to swap out the light bulbs as easily if one were to burn out. By the way, thanks for the light bulb comparison test that you did.

I’m talking about this style. Is this the type you have? If so, how did you get that plug from the supplied harness in that housing ?

Yes, that's the style that I have. the closed headlight bucket with the flat faced profile of the new H4 koito headlight shown in the pic above.

The wires need to be pushed out from the OEM socket and fed through the small opening of the headlight bucket individually . The photo shows the socket on the left and the wires when pulled from a socket on the right.

Once each wire is fed through the hole of the bucket , you can connect the wires back into the OEM sockets and hook up the headlights.

However, I do wish I had the open-style headlight buckets for ease of changing out the lightbulbs. The way I have it set up isn't any different than how it was before with my sealed lights, though.

Right. Cool. Yeah I did not say it was Not doable just not a quick plug and play. Thanks for adding that.
 
Fantastic report, Nolen!! I thank you. Just got my new harness installed today and tested the Phillips lights tonight. Totally pleased.

Wish I could buy a similar kit for my '92 Toyota pickup which has the H4 rectangular lights. Does anyone know if such a kit is available? I would buy it in a heartbeat.

Another approach and one that is just a bit more involved is cutting the wires on the harness side and then rebuilding the harness. I felt like there was tons of extra wire length so I chopped and rebuilt to the length I wanted.
