question about hella e code h4 on 2013jk

Hi,
I feel the stock headlights on my 2013 jku are so lame, so decided to do some easy upgrade(no re-wiring).
Right now I have two (dumb) questions that basically can be answered by yes or no.

1. will Hella 7" Round E Code H4 Halogen basically the this product:

Hella 7" Round E Code H4 Halogen Replacement Headlight Kit with Standard 60/55W H4 Bulbs : Amazon.com : Automotive

fit 2013 jk?

2. To convert the stock h13 light bulb to h4 bulb, all I need is a adapter right? Since I feel h13 and h4 basicall working at the same voltage and power.

Thanks very much, I just want to make sure everything before I order something online, since I got little experience about everything.

B.T.W, I am also very curious how much difference does it make by just change the bulb(like the Sylvania bulb).

Hi JaysGolf,
What is the difference of this one and the on Amazon?....The price difference is way to much that it is definitely out of my budget.

I had the same questions and I just got off the phone with Dave @ rallylights.com and he was very helpful .. I'm goign with the kit they sell on thier site because it includes everything you need to do it right.. You get the wiring harness which feeds the full 12 volts to the lights instead of the stock system at 10 something volts. That in itself will generate more light output, coupled with the lenses and the new bulbs its that much better. He also explained to me the kit on Amazon would still need the adapters from h13 to h4, but would still be at lower voltage which i believe are 20 bucks a piece. Great guys that know thier stuff, call them and they can explain more if you have more questions.

Quite helpful information! Sounds stock harness eats up lots of voltages!

But I am not expecting too much, I think the one on Amazon will meet my expectation, because I was thinking about just change the light bulb at the beginning. It seems I need another pair of h4/h13 adapter for everything to work.

You can always add the harness later if your needing more output. I would suggest sticking with standard watt bulbs if your not upgrading the wiring.

Oh yes, that is all I am going to do. The stock headlights are so lame (high beam=nothing), that anything I do I think will some differences.

Its not that the stock harness eats up voltage. The stock harness is small gauge wire so it would limit the amount of amperage it could carry. The headlight circuit runs off pulse width modulation. The voltage is constantly fluctuating back and forth between like 6 and 12 volts.

biggest difference is what hangemhi eluded to, the kit is just that, a kit. they provide everything you need in a single box. and their customer service is second to none in this day of monster corps who see you as a number.

for someone like me, who is not that savvy, or at least not savvy enough to know which 3 stores to go to get 4 necessary parts, this was ideal.

Hi,
what do you mean by "voltage is constantly fluctuating back and forth between like 6 and 12 volts"

Are you saying that the electric current run through headlight bulb is ac rather dc?

The people at Rallylights.com are the best, great product, great service. In my opinion the best mod you can do for the dollar. As the others said the stock wiring harness is too small to power the head lights properly.It is not ac current, just not a constant steady 12 volts.

The people at Rally Lights are really good, and helpful. I drove to their old shop, and it was a good time. They showed me all their stock on hand, and I got to talk to the gentleman that builds the harnesses. I had a set of IPF H4 lights that a friend gave me for my 2012 JK. I only put in 85 Watt bulbs by Phillips. I can see now, although they aren't quite as bright as the 100 watt bulbs I have in my '98 Cherokee. They should last a little longer. The higher the wattage = the shorter the life. Before I put the harness in the IPF lights with regular H4 bulbs did work better than the stock bulbs. The IPF lights came with the change plugs and IPF white bulbs. I didn't like the way the blue/white bulbs looked so I put regular H4 in. The gentleman at Rally lights said that the blue tint bulb just block out part of the light spectrum, and make it look brighter although they really just give out less light.

Thanks for all of you guys input. Let me summary what I have learned.

Basically, if you want to upgrade(exclude hid conversion), you can
1) change the light bulb, like Sylvania or Philp

2)change to h4 housing, which could be Hella, IPF or Delta

3) upgrade stock harness, and I think this kit will do the job(also can be found in local autozone)
Putco 239008HW Premium Automotive Lighting Wiring H13-9008 100W Heavy Duty Harness and Relay : Amazon.com : Automotive

Of course, if you do all of three above, you will get the best result. However, depends how much spare time I got recently, I may try to do them one by one, and see which one give the best result for money and time.

I've been looking at options on how to do the suggested upgrade (Hella's, Phillips bulbs and harness) as cheaply as possible. Suffice it to say the Hella's and bulbs are pretty standard as far as price goes. I did come accross the following harness though at a fraction of the cost of the Rallylights or Putco harness. Anyone know it it would be a viable alternative?

Why not just purchase an H.I.D Bi-Xenon conversion kit?

So you can't see that much better, and you are blinding oncoming traffic because of the screwed up lighting pattern.

By going with the Hella housings you get properly designed reflectors and optic quality glass lenses that puts the light were it does the most good. The Hella housings have a very distinctive cutoff so you aren't blinding other drivers. You also get to use bulbs that you can replace at any Walmart instead of having to order them.

You really have to try one of these housing upgrades to understand just how big of a difference they make. I have the Hella upgrade from Rallylights.com.

If you want a more detailed explanation, you should read through Daniel Sterns website.

My question was more along the lines of whether the harness in the eBay listing could be used as a cheaper salternative to the Rallylights harness together with the Hella's and Philips bulbs. Said differently: Does the listed harness do the same thing as the Rallylights harness? (I know its for use with an HID conversion but I'm not looking to go HID - So my thinking is what the heck, if it does the same thing as the Rallylights harness I can save some $$).

Without seeing a clear picture of the exact harness or a wiring diagram it is hard to tell what you are getting with the harness from ebay.

I do know that my rallylights harness has two relays and this one only includes one, so they are not apples to apples.

Also, please note that the Putco harness on Amazon does not show both H13 and H4 connectors. It looks to be just a way to run a set of H13 bulbs directly off the batter, not a way to convert from H13 to H4.

Not sure if the two pics were taken under the same circumstance(I think they were). But here are the pics before and after install hella e code.

Just changing the housing, no harness upgrade, standard $4 bulbs. I feel this is enough for me. Notice how much more detail you can see on the ground.

What brand and wattage bulbs did you use?

And where did you get the H4 to H13 adapter?

thanks

I am using hella standard 60/55w bulb with model number h83140101.

And Delta h4/h13 adapters on amazon, not sure if there are other choices.

That is a pretty impressive upgrade for less than $100.00

Question

At what wattage does when need to install an upgraded wiring harness like this ?

Amazon.com: Putco 230004HW Premium Automotive Lighting Wiring H4 100W Heavy Duty Harness and Relay: Automotive

I presume this harness will take the place of a H13 ---> H4 harness adapter if one where to use H4 bulbs correct ?
