Headlight upgrade for 4 bulb system

Looking for feedback from people who have made the upgrade and have a 4 headlight arrangement.

I made a legitimate attempt to search the subject here and Google but still have questions.

My main criteria is it must look like a T3.1200 lumens OEM-style halogen replacements are probably not bright enough for me.

I don't see 4 bulb kits that work like OEM, Low beam 2 filament, high one. Am I overthinking this? Do I simply install 4 of the same bulbs and burn the retinas out of all oncoming traffic??

I have 14 VDC to the headlights.

Questions for the crowd:
-What brand did you use?
-Do you like it?
-Did you install 2 or 4 bulbs?
-Lumens each?
-Dollars spent?
-T3 look-alike with glass globe or other?
-Plug and play Y or N?
-Any additional amp load on the system?

This is what I'm looking at. Headlight experts two bulb kit:

I love my E code headlights, not a T3 twin but not obvious either, check my post #6 in thread below. Other than a scrutinized appearance difference from T3, they would do exactly what you want. Some folks are happy with some of the new LED offerings but appearance may not be close enough for you. The only downside of the high watt bulbs is current draw, easily managed with relays and heavy wiring but 4x 100 high beams pull some juice. I can’t remember if I wired my low beams in with high beams but if they are, add 100+ watts. I love the brightness high or low, the pattern for visibility and also for not offending oncoming traffic.

Just looked at the lights you linked, they look pretty nice and you likely avoid the heavy wiring due to reduced current demands of LEDs.

I replaced my sealed beam headlights with the Hella H4 E-code kit in bccan's post above. I added relays at the same time so I can't comment on headlight switch, circuit breaker issues. You will need to open up the hole in the headlight buckets to make room for the rubber boot that seals the backs of the Hella housings. I like that they are glass and not plastic (as are some replacement kits, including most LED kits), one other thing that I especially like about the Hella kit is the flat face of the bulbs compared to the stock T3 bulbs. The flat face is pretty subtle but I think it adds a modern styling to the front end. Here's a close-up pic of the Hellas:

X3 for the E-codes.

How did y'all go about the relay mod?
Ice cube? Rating?
Whare did you locate the relay?

I used three, 20 A ice-cube relays. One relay for the two low beams, one relay for two inner high beams, one relay for the high beams that are in the outer, hi/low bulbs.

The relay with the highest load is for the two low beams, and it supplies less than 10 A.

I made a bracket for the relays and put it behind the battery, so you wouldn't notice it. I fed the relays from the battery through circuit breakers for each (I didn't want a fuse or fusible link to leave me in the dark).

The OEM headlight wires operate the relay coils, and they are accessible behind the battery too.

I ran 14 ga wires from the relays to each headlight. After the wires are vinyl-wrapped, you don't notice how fat they are.

The hardest part was to find the large slip-on wiring terminals that connect to the back of the headlights. I disassembled junk-yard wiring to get those, but have since seen them for sale.

I was amazed that my stock headlights were about 50% brighter from this change--even before I installed E-Codes.

Cibie and Koito are some other brands to consider. I have purchased from Danielsternlighting.com and have been happy with the results. His website has a ton of information too.
