Headlight Upgrade- New Koito 7"H4 Headlights + Relay Harness

[theastronaut]

Pair of new 7" Koito H4 headlights with bulbs and plug and play relay harness. Very high quality; Koito is an OEM supplier to Toyota. Glass lens with metal reflectors, positive locking bulb retaining ring. I have multiple sets available.


Excellent beam patterns on low and high beams- ranked as the best performing 7" halogen H4 headlight available on candlepowerforums, beating both Hella and Cibie. No glare for oncoming traffic on low beam when aimed properly. I use these in my own cars, the long distance visibility on high beam is incredible. No modification to the original wiring harness needed. These are perfect if you don't like the look of modern 7" LED headlights and want to retain the classic fluted lens look.


$99 plus actual shipping, send your zip code for a quote. Paypal, Venmo, Cash App, and USPS money orders accepted.


I had a PM asking if these mounted like stock, thought it would be good to add this to the ad- They mount up and plug in just like stock sealed beams, they have the same three locating tabs and are held in with the same ring as stock. The only real difference is the rubber dust boot to seal the bulb on the back side; some cars have really small openings in the back of the buckets with only enough room for the harness/connector to fit through. In that case the back of the bucket might have to be opened up to make room for the boot; the part of the boot that protrudes is 2 3/4" diameter. I had to slightly open up the back side of the bucket in my '66 C10 to clear the boot.

I currently have three sets left, but should be restocked late this week or early next week.

[ryeguy2006a]

I got the headlights last week. Very nice, can't wait to get a project to put them on haha.

[mikewoods]

Any chance you can get some 5.75" housings for the 4 bulb cars?

Glad they got there safely!

Koito does make 5.75” lights and they’re also better than Cibie/Hella, but I wouldn’t really recommend any H4 low/high in 5.75”; there isn’t enough reflector area for adequate lighting. In a dual filament light the low beam only uses half of the reflector to create the beam pattern. Half of an already small 5.75” reflector isn’t enough to multiply/distribute light.

If you can find them, Hella Bifocus H1 5.75” low beams are low beam only so the reflector isn’t limited to half of the reflector and are much brighter than a H4 5.75”. They also are fluted glass lens/metal reflector so they look at home on classic cars.

Daniel Stern Lighting has 5.75” Koito H4, and two different versions of a high beam 5.75 if you’re set on H4 5.75’s.

Two sets to 98826 please.

Many years ago I ran Cebie H4 55/80 and Marchal H1 100W in a mid 70's Capri. We were running up to Ely NV for the Silver State. I had a 43A alternator on the car and we flattened the battery charge during the run on the Friday night (we left from Los Angeles after work). But it sure lit up the desert.

Over the years the reflectors corroded, and I recently bought the referenced Kiota H1 & H4 lights from Stern to replace them.

[BonzoHansen]

Just want to say I gotta set within days of making a payment. Thanks

Maybe this weekend all install and see how they are.

Let us know what you think! I've been driving with them in my '66 C10 for about a month now, and had them in a Miata last year. The added light of the e-code pattern on low beam on the right side of the street is really nice to help read street signs at night; DOT pattern lights don't cast as much light in that area. The high beams are the best part though, they reach way out but still have plenty of peripheral lighting.

Hi, are the len's surface "curved" or domed or do they have a flat face? Hard to tell in the pictures.
thanks

They are flat faced. Here are a few pics of them mounted in the same body style trucks, sealed beams on left vs Koito on right.

Thanks to theastronaut,
Received mine in record time, look forward to getting them in my project as well and checking them out.
Thanks again.

[vcho455]

Received mine on Friday. UPS seemed to have some kind of problem as the tracking never updated.
Well packaged with bulbs!
Thanks to the Astronaut.

[theastronaut]

Bump, I got another shipment of these in this week.

[markaaron80]

PM sent. Let me know where to send $$

[Dodge383fi]

Are you still selling these?

[JuStBlAzIN]

Also interested in a set .. 94066 zip code

[theastronaut]

The source I had for these stopped accepting orders so I haven't been able to get another batch in. Still working to find another source.

[Bygblok]

can you get the smaller size for 66 chevelle's etc? I can use a large set on my 70 Camaro but the small's would be awesome too!

[AUTODYNAMICS]

I will take a set
Let me know what is needed

[Twentyover]

Reviving an old thread-

Another forum I'm on (MG Experience) just noted there is a smokin' deal on these- from an OEM Source.

Toyota P/M 81110-60P70 is a se of 2 LHD reflector/lenses, bub, and relay harness. Looks like E-code lights (flat face). Some on the exerience have found them for as low as $20 for a kit, I just bought a half dozen kits for $40 each for my own use. No financial interest

As noted, Daniel Stern indicates these are the probably the best 7" reflector/lense- and he gets $179 for a set. Not tryin' to each his lunch, but... Damn! for a coupla Jackson's the deal with relays was too good to pass up

I've noticed similar posts in Miata facebook groups in the past few weeks, guys saying they were approximately $20 for a pair at Toyota dealers. You'd think they'd be counterfeit at that price (under half of what I used to pay in 2022 buying them in bulk/wholesale before shipping was added) but they're coming direct from dealerships so it seems like they're legit oem Koito. Just googled the part number and found one place selling them at $16.92. I'm going to grab a few sets to have on hand for replacements/future builds.

If that's the place in Dubai, they want like $120 for shipping....

Just sayin'


Edit- whups, that was on ebay

[JuStBlAzIN]

I got the set of lights from Toyota. Has anyone installed this on their camaro? Are they plug and play or do i need to wire them in with the supplied harness and relay? This is for a 69 camaro

[theastronaut]

You don't have to run the relay, they'll plug into the stock harness- same style connection as a sealed beam. But, check for voltage drop under load and use the harness if there is any difference between alternator/battery voltage and voltage at the bulb. A small amount of voltage drop will really kill off output with halogen bulbs. I could visibly see a big difference between 13.8-14.0 and 14.5 volts back when my C10 had the stock adjustable voltage regulator and I could adjust it up to 14.5.

Plug and play. I had to work the housing in a little but it all went in with no cutting. Superior light difference at night. Thank you for your help.
