I’m looking to replace s the entire headlight assembly, not just the bulbs, with some brighter lights and preferably LED. Are there lights that I can buy that just plug and play into the existing headlight wiring harness? Any recommendations?

Yes I saw that but was looking for suggestions on what would be good quality. They range from 100$ To 1000$ per set. Also if they are all plug and play direct replacements

Nothing is "plug n play" with these trucks unless you stick with OEM, halogen bulbs.
If you move to LED or HID, you are going to need to run an aftermarket harness of some kind and resistors to fool the computer into thinking it has got halogen bulbs in place.

Also, be advised, don't just put HID or LED bulbs in your stock housing. The reflectors do not aim the light properly (it doesn't matter how you AIM) your headlights. It will produce a lot of scattered light and hotspots and throw bright, dangerous light into oncoming traffic's eyes.

Proper way to do it is install a projector into the OEM housing and THEN install HID's. This is either a DIY or pony up for a company to do it for you that does headlight retrofits. They aren't cheap.

What is the reason that it messes with the computer? What problems exactly does it cause? I found a few lights that say they are a direct fit and mount to the existing wiring harness so I’m interested to hear more

Re-read my post.

The computer needs to think there are halogens installed. The current draw of HID's and LED's is lower. If the truck doesn't detect the proper parameters during startup, it won't even turn the lights on and/or you will get a "lamp out" dash warning. Which is why you need resistors. There is a lot of information on the web about resistors, canbus, and ohms law (as well as on this site if you search).

I reiterate, do not put LED or HID bulbs into a OEM reflector housing. If you need more detail on why there is a lot of reading on the web, but I explained it to you in a very boiled down version.

Listen to this guy, he does know what he is talking about with these lights.

The only after market harness I have found is for 2009+. Can somebody point me in the right direction for a harness that will fit on a 2007 ? I do not mind paying whatever it costs. I’m tired of having very poor vision at night

I did these...


... and they work awesome however they are not 100% plug & play. Bought a resistor box thingy (yeah and I'm a test engineer hahaha) that went between the oem harness and the bulb. There is a problem however where one LED is on high while the other is on low. Never did go back to fix this yet, I suspect this is just a wire swap in the resistor box thingy harness. Light out put is great, not perfect but it is significantly better than the halogens.

6 pages of troubles it seemed... And they still don't work properly?

I never did see output shots against the wall. I venture to guess these might be slightly better than the Amazon bulbs for cutoff but still...LEDs in a halogen housing correct?

Cell cameras seem to take clear pictures of scattered light (and hotspots). I'd still be interested (was in that thread too) on how bad/good that cutoff is..

Yeah they are not perfect but once they were with the piece from Amazon for the lamp out fix they are doing OK. They are still installed along with the driving lights, cant imagine driving with halogens again. The issue with the high beam, just never dove into it again to fix it. As far as cutoff goes, I have had only one person complain and they were cresting a hill as I was coming up. Other than that one time, no one ever seems bothered by them. As far as the light output goes, way brighter than the halogens. Never did get halogen shots against a wall so it would be tough to compare against now. I'll take & post them if you still want to see them. Tell me how far from the wall...

edit: I do still have the first pair that I will use to figure the solution out with... Its just way down on the priority list atm. 50k maint starting this weekend... :D

Is this legit?
I encourage you to re-read my first reply and then Google search on why dropping LED or HID bulbs into a stock halogen reflector housing is not a good idea...mostly for OTHERS safety. There are forums out there dedicated to lighting and it only takes a few minutes to dig up those threads.

Ok I was under the impression that the main safety concern for oncoming traffic was the flickering caused by some lights. The ones I posted claim they do not flicker or cause engine lights which is why I was asking about them. They’ve been “engineered” to fix those problems supposedly

Flickering? Not sure what you're talking about there. No lights that are properly working should flicker.
I think what you're talking about is "flickering" due to fooling the canbus system on the truck. Which I've gone into a little detail about...the LED's or HID's will turn on for a second then turn off when the truck doesn't detect a proper halogen bulb in place. This, as well as any dash errors, are completely independent on what is going on when you put those bulbs into stock halogen reflectors and shine them down the road. That has everything to do with how LED's/HID's emit light vs a stock halogen bulb.

Be careful with the word "engineered"...it's catchy. There is enough information on this thread now (and on this site) to do some research about HID's, LED's, and halogens. Arm yourself with knowledge before you make a decision like this.
