Default Headlight replacement question

I have a 1994 Cherokee and the headlights seem dim to me. I would like to upgrade to a brighter light and need some advice. I don't have a lot of money to invest. Can anyone point me in the right direction?

Best headlights I've ever run. I like them more than HID retrofits.

They look cool too:

Putco harness , Autopal ecode h4 housings (not the crystal cut bs) And some good bulbs 100-150 total and it'll make your low beams brighter then your hibeams

I understand you might really hesitate because of the price, but I'm telling you, it's totally worth it!

They're super bright, super durable, draw little power, and best of all they last a long long time.

Here's a DIY solution and a good explanation of why stock XJ headlights are often very dim.

They are plug and play, and they're DOT SAE approved so they don't blind everyone

Individually.

To those recommending the Putco harness, there looks to be many 1-3 star reviews on Amazon with people having problems with the relays often (and by often, I mean within just a few months after installing the harness). I had considered the harness in the past, but this kept me from making the purchase.

It looks like many people are having problems with the relays not lasting, and with blinkers, high beams not properly functioning after the install. To me, it seems like it's a cheap product with too many inconsistencies, and not something I would want to run on my rig if I depended on reliability.

It seems many users even on this forum had issues:

And more than that have NOT.

My theories are as follows.
1) The ground contact point is not clean enough. This causes the relays to get hot and fail.
2) The relays are not fastened down in the engine bay or are mounted upside down allowing them to get moisture inside.

I personally have installed more than 4 Putco harnesses, the first one being 4 years ago and with 90/100 bulbs in the Autopals, and have had NO failures.

As to the problem switching from low to high, that's a Jeep wiring conflict on vehicles with factory foglights.
Courtesy of EZEARL




Suppose to be the fix:
If you have stock fog lights on a 97+ and upgrade your harness in a manner that uses the factory wiring to trigger some new relays, your fog lights will have and/or cause issues unless you make some additional modifications to address the problem. It doesn't matter if you use a plug and play harness like the eautoworks or if you split your harness open and completely strip out all the extra factory wiring like I did. The factory fog circuit will cause your new lighting system to not work properly.

If you do nothing, your headlights will work as mentioned above. Low beams will be fine, but after you turn on your high beams, they will not turn off again until you completely turn off your headlights. Big issue here is that when you switch back to low beams, both the high beam and low beam filament will be remain powered causing your bulbs to endure 115W worth of heat output instead of the 55W or 60W that they are designed for. From what I've read this can cause them to overheat and burn out within minutes.

So what is happening? If you look at the driver's side headlight plug (and you have factory fogs) you will notice there are two red wires coming out of one of the terminals. One is a small 18g Red wire which sadly is the stock high beam wire. The other is an even smaller 20g Red wire which ties into Fog Lamp Relay #1 in the PDC. Please keep in mind that Fog Lamp Relay #1 is NOT used to provide battery power to the fog lights the way we commonly use them with aftermarket lighting. It is located before the switch and simply cuts power to the Fog Light Switch unless the Headlight Switch and Beam Selector Switch are in the proper positions. It does this as law dictates that you can't run your high beams and fogs at the same time. Though not a problem here in CA, I've read that states with safety inspection programs will fail your vehicle if the lights don't operate this way.

I dug into the wiring diagrams but had to have kastein help me decipher them because there was something about this circuit that just wasn't making much sense to me. I still don't understand the function of Fog Lamp Relay #1 in its entirety, but we're only concerned with the part that is affected by the headlight harness anyways. Essentially, when your Headlight Switch is off, the relay coil receives no power and therefore won't allow your fog lights to come on. When your Headlight Switch is turned on, one side of the relay's coil receives 12V which causes the relay to activate and send power through to your Fog Light Switch. When you turn your high beams on, 12V is sent out to your headlight socket via the Beam Selector Switch, and then is sent back to the other side of the relay coil via the skinny Red wire on that shared terminal. This brings both sides of the relay coil to 12V, thus causing it to deactivate and turn off the Fog Light Switch. Weird huh? The factory designed it so that the relay is off with both sides at 0V, on with one side at 12V, and then off again with both sides at 12V. While it makes perfect sense now, this is the part that was confusing me.

So what's the problem then? Well, it turns out that even when the high beams are off, there is still approximately 5V on that skinny Red trigger wire for some reason which I still don't understand. While this is obviously not a problem in the factory configuration, it becomes a problem when you are using the high beam wire (which is directly tied into the skinny Red wire) to trigger your aftermarket high beam relay. A typical automotive relay requires approximately 8V to activate and needs to drop to somewhere below 1-5V to deactivate. When you first turn on your lights there is no problem because the phantom 5V is not enough to activate your new high beam relay. When you turn your high beams on, your new relay gets 12V and kicks on. When you go to turn off your high beams, the phantom 5V keeps the new relay from deactivating and voilą, your high beams are stuck on...

So how do we fix this? There are a few common suggestions that are out there that I just wasn't happy with, and a few that sort of work, but not as required by law:

1. Don't use your high beams, new lights are bright enough anyways (OK...)
2. If you have to use your high beams, turn your headlights off briefly to get them turn off (PITA)
3. Pull various fuses (lose your fog lights)
4. Pull the fog lamp relay (again, lose your fog lights)
5. Modify the fog lamp relay (fog lights work, but won't cut out when your high beams are on?)
6. Install a jumper in place of the fog light relay (fog lights work, but switch is always hot?)

One post I saw got it right though. lilredxj99 mentioned it in another thread which I didn't find until after the fact. The details were a little fuzzy and I still thought the issue deserved some further explanation so that's why I just wrote this damn novel...

Oh yeah, so the right way to do it... Cut the 20g Red Fog Lamp Relay #1 ground/trigger wire at the back of the driver's side headlight plug. Extend this wire using your preferred method so that it is long enough to reach your new aftermarket high beam relay. Splice it into the 87 pin (output) of your new high beam relay. If you have two 87's (which is ideal), either one is OK. Do not however use 87a if your relay has it!

Yep, that's it... Your high beams will now turn off when they're supposed to, your fog lights will turn on/off when they're supposed to, and your low beams will continue to work as they're supposed to. Sure you could have skipped all the way down to the bottom and found your answer, but you wanted to know how/why it works, right?

I've had the Putco harness (w/SilverStars)in my XJ since the fall 2012. One relay replaced after maybe 6 months (no big deal as things do happen). Still I've been more than satisfied. Alot has to do with the installation . Not that it's complicated by any means but like any electrical system you'd best make sure you get good grounds.

I posted something a long while back about that fog light issue. I can't be given credit for designing the fix. I just happen to come across it during ALOT of searching to find a solution to the problem. Wasn't any name with the fix to give proper credit to though. So here's to the person wherever and wherever they may maybe.
