Daniel Stern Lighting

I have decided to upgrade my headlights, but not do LED. I've been talking with Daniel Stern about recommendations he may have . We landed on

Koito - Headlamps
Tungsram H4 bulbs
H13-to-H4 adapter harness.

I'll post up how they look after i get them installed and aimed.

Decent LEDs are nearly 2x the price I'm paying for this approach.

I think you'll regret not going the LED route.

Not necessarily.

I went from JW Speaker LED to Hella H4 halogen setup and have zero regrets. Not going back to LED anytime soon.

I'm not so sure. I believe led does not penetrate as much as it 'spreads'. We will see.

I drive a lot on pitch black Mountain roads. Kangaroos are a real hazard and they a plentiful.. The stock H4 Halogens were not up to the job. My Stedi LEDs are great.

I agree completely, the stock lights are not up to the job after the sun goes down!

My upgrades will greatly improve the performance over stock. I"m glad led works for you and I hope I do not regret my decision later. Stay safe.

I'm curious what headlights you're referring to. Mostly because my company is within the Koito Group of companies, and I'm only aware of what they produce for Japanese automotive plants and for our own lamp designs.

I think no matter what you do, you won't regret stepping away from the factory headlights. I just replaced my Sealed7 HID headlights with Super7 LED headlights (due to continued sealing and fitment issues) and so far I'm pleasantly surprised by the LEDs, even though they look a bit funky. Both of them blow factory out of the water though.

Koito makes some really good lamps.
Which model? I'm surprised Dan didn't steer you to a Cibie ---- maybe it's a newish Koito?

I think any upgrade to get away from the stockers is well worth it. I knew the stocks were not great, but didn't realize how poor until I swapped them out. geez. I can see things now.

Dan also told me a couple of months ago that he had a stash of H4 to H13 full bypass harnesses that he was trying to liquidate. Using a harness like that you get ~14 volts to the bulbs rather than ~12.8. Makes a huge difference in LUX.

Just searched on these Koito headlights and found this:
Koito European Spec (E-Code) 7" Round Headlamp

$205 for the Koito e-code headlights & Tungsram bulbs from them. With the harness you're at around $350, right? Not too bad.

I think you'll be happy with this setup, as long as you are not concerned about having the higher color temperature of LEDs. I have JWS led headlights and I like them, but the hot spot in the center of the beam still bothers me after years of use.

Sorry, for the delayed response. It was $310.

Here is Dan's reply regarding the headlamps...

" The very best replaceable-bulb (H4) headlamps in the 7"
round size you need are made in Japan by Koito, $189/pair.
They are the most efficient (greatest amount of light on the road),
best focused (most useful distribution of light), best-built
(sturdiest glass and metal materials, most careful build quality)
lamps of their type in this size.

A fairly sizeable step down from there is the Cibie H4 units,
$168/pair."

I took a gamble at the 'jumper' H13-H4 harness instead of the full one. Now you have me doubting myself...

He steered me directly to the Koitos. He was pretty strong on their performance being significantly better than Cibie...

I was at my budget with the short 'jumper' harness, so I skipped the full one. Perhaps he sold out of the full bypass harness and this is why he did not suggest it to me. Regardless, I'm looking forward to the change over.

He had a bunch of medium-duty harnesses that he made for a different enthusiast-class vehicle.
If you want more light in the future, go straight to Dan's supplier at rallylights.com and talk to Ray or Dave. They build a great harness.
Just don't use over-wattage bulbs with the jumper and you'll be fine.

Daniel just shipped my package. Hopefully this coming weekend I'll have time to install the lights and update this thread with installation feedback and the results.

For what its worth, I have been running lights/bulbs from Daniel now for a number of years (upgraded my stock lights/bulbs) with great results. When I did my upgrade he recommended the Cibe lamps with Osgam bulbs. Again great combination. You cannot go wrong with his suggestions if you want to stay with Non-LED lights.



I have a write up on my lights install if you want I can send it to you. Just PM me with your email.


hope this helps

The Cibies are a mild improvement over stock. I had them and got rid of them. It is hard to beat good HIDs and good LEDs come in next, I believe. I have heard good things about Koitos but unless you up the wattage, the improvement is not going to be night and day. Keep us posted. I now run JW Speaker LEDs and they are quite decent. On my 4Runner, I am looking at going with HIDs and a good projector retrofit....some more research needs to be done.

They have arrived! With what appears to be a bonus piece! i’ve attached a picture of what appears to be a full harness! No instructions though, but it appears straight forward. Anyone have the full harness instructions from Daniel Stern?

i’m emailing him about the instructions too.

Secure the relays somewhere.
There should be one H13 plug on the harness; plug the old H13 end from your passenger side headlight into it. Run the two long H4 terminals (one wire should be longer) to your new lights and install.
Find the red end and black end and attach them to the correct battery terminals (making sure everything is tight afterward).
That's about all there is to it.

Note: with full power to the new bulbs they won't last really long. I used to change mine once a year to ensure full brightness.
And those lights were made in Belgium. Interesting.

Thanks.

I opened up the harness to check it out and I pretty much surmised what you describe above. I was unsure which H13 end I connected the single H13 connector to, so thanks again for the instructions.

I'll order a backup set as spares to keep with me in the Jeep should I lose one while I'm out wheeling or camping.

I completed the install this morning. It took much longer to route the new harness then it did to install the lights. These lamps are significantly more robust than the plastic oem housings. The Koitos also came with H4 bulbs, so I'm keeping them as emergency spares in my Jeep.











I'm off to go aim them now...

I love the look of a traditional style glass housing compared to the alien/zombie/robot/insect look from LED.

Looking forward to your review

I prefer the warm color of non LED, but led makes it so simple.

If they make LEDs with 4000 kelvin and high cri, I'll be all overthat.

i’m happy with these! the cutoff is so distinct and i am no longer getting flashed or blinding people when i pull up behind them. here is a quick pic from last night leaving my friend’s place.

i forgot about the flash so it is not the best.

i do notice a whine through the stereo when the lights are on now. i’m wondering if i need to add a ferrite coil to the setup or if i messed up running the harness. it seems pretty straight forward and i do t have any codes or fluctuations in the voltage read out from my jscan.

thoughts?
