4Low2G0 I also run Hellas and have since the early 90s they work great, however the relay is needed
to get full battery voltage to the bulbs for the most light on the road.

The E code lights have a very distinct cut off that avoids blinding on coming traffic but does not
illuminate reflective road signs as well.

US spec lights are designed to illuminate road signs that is why the beam pattern is different.
I have not found this to be a problem in over 30 years and love the extra light on the road.

For the fogs 2 100w lights at 12.5 volts will draw 16A

BlaketheSnake I've got both Hella and KC H4 light housings with LED H4 Bulbs and the Hella is my preference.
I've had the Hellas since 1995...hard to beat their beam pattern.

53flattie Just to put a bow on this topicÖ. Thanks for all the advice on H4 headlights. Several of the mentioned brands are on back order (shocker), so that upgrade might be a little further down the road.

Re: the new Warn fog light wiring - just for giggles, I used some temporary wiring to power them via the old fog light wiring versus using the supplied wiring harness and relays (wired directly to the battery). Wow - what a difference. I would venture to say the lights were 30-40% brighter when wired to the battery. Iíll be going that route and using the factory wiring just to trigger the relays.

Now for a new thread on a power distribution centerÖ

CJ7-Tim For the best performance from an H-4 upgrade, you need to upgrade the wiring as well. You can buy a complete plug and play H-4 headlight wire harness and the fog lamps should also have upgraded wiring. You can use the stock fog lamp wiring to trigger a relay, and power the fog lamps from the relay. That way all the stock driver controls remain in place and should function as normal.

53flattie Thanks so much for the advice.

One more question - will the stock fog light wiring handle these new fog lights? I would prefer to use the factory wiring and relays, so I retain the stalk-operated switch and high beam off functionality.

The lights havenít arrived just yet, but I know they are 100w. I just donít know how many amps they draw.

rsurran On my 2003 I converted from stock to PHillips H4 60/55w bulbs and Hella housings. They were not plug and play, I had to also put in a 9003 H4 headlight relay wiring harness kit. Now 3 years later I donít remember why I needed the relay kit. But I was really happy with the finished product.

CJ7-Tim Any all glass H-4 lamp should be just fine. I have Hella in my 00 XJ, I have AutoPal in my my 98 XJ, and Cibie in my CJ-7. I use plain white halogen bulbs. Avoid any plastic H-4 housings, and housings with Diamond or Crystal in their name or description.

LumberjackLloyd Hella's are not optically correct. You can find this explanation in various places. Koito's are by far the best H4 you can buy, I will find the Toyota part number. You can also buy through Daniel Stern lighting.

Toyota PN 90981-01035. RHD Koito E code lamps. They come with basic H4 bulbs, I would upgrade to a Phillips Xtreme Vision.

natedenver Most people will recommend the hella. I have had the ramage and hella. I am sure there is a difference, maybe even a big difference but when I drive in the mountains, they both work great for me.

As for bulbs, there are a couple great write ups. Not sure about the links. But after reading the write-ups and doing way to much research, I settled on these:

They work great. They don't seem to blind people and are the proper type of led bulb do that the light is aimed and directed properly. And 4.5 stars in Amazon with 3640 reviews is pretty solid.

They are kind of a pita to install but that may just be me fat fingering them.

H4 Headlight Recommendation?

I recently purchased some old(ish)-school Warn fog/driving lights. I really like the period correct look of them, and didnít want the spaceship look of multi-LED lights. I was surprised to discover that Warn no longer makes these, but I was able to find a set on eBay:

I also want to upgrade my original headlights. I want to stick with H4, so the light quality matches the fog lights. In looking around the interweb, I see several options for H4ís - Hella, KC, Rampage, and IPF. Does anyone have experience with any of these brands? I assume they are all plug-and-play, correct? (No changes to the wiring harness or relays to add?)
