Alpharex G2 Pro Series Headlight Install on 4th Gen Ram 2500 (2009-2018)

[@TheCudamaster1]

I just installed these lights on my 2015 RAM, the drl box has the positive plus the negative wire along with the gray wire. Also I have a yellow wire coming out of the drl box as well. Is this yellow wire needed.

[@Kyan_17]

No shit, it came with it💀😂 no its just there for show

[@xSLIINKx]

no, the yellow wire isn’t needed for normal setup.

[@joeypicazo]

I used the yellow wire and connected it to the blue wire on the harness for the headlights. So when you unlock it the switchback pattern turns on. It will take. Like 15-30 seconds to turn off after you lock your truck.

[@osubuckeye502]

Just a heads up for anyone wanting to know how to adjust the beam. you use the same hole you'd use for factory lights. Use a Philips screw driver and it'll turn the metal adjustment knob on the back like a gear.

​@@MKSPerformanceOffroaddid you ever switch the bulbs?

[@MKSPerformanceOffroad]

@@Jay-Go I have been running the LED bulbs for a while now and have had no issues. Some folks have reported lower light output with led bulbs due to light pattern not mimicking a halogen light source. Best I can say is try and find a bulb that mimics a halogen light source if LED is the route your going.

[@dennisjaye7221]

Great video brother... thanks for the DRL wiring info. Big help on my install.

[@BadGoat92]

I have these exact lights in almost the exact same truck. My drivers side low beam will randomly turn off….sometimes it comes back on after about 3 seconds, sometimes it just stays off. Ive tried 4 different sets of led bulbs and 2 different halogen bulbs. It does the same thing reguardless. Ive narrowed it down to a wire/harness issue in the headlight housing itself. Im about to just throw then alpharex’s out and get some cheap $90 ebay units

[@Jay-Go]

I see you posted this about 8 months ago. But the issue is probably not the headlight itself. More than likely, it's the green wiring harness that comes from the truck. This is the wiring harness that connects to the harness on the headlights. The Mopar harness is known to go bad.

[@BadGoat92]

@ I might have to do some digging. I have noticed it does it more on rainy/damp/foggy days. Whether that means anything or not

[@Jay-Go]

You should be able to pop open the hood and reach into the headlight well. Feel around for the headlight cable where the truck harness connects to the headlight harness. Obviously, it's best to do it at night when you can see the lights. If you wiggle it and the light flickers off and on, then you'll know it's the harness, and more than likely it'll be the truck harness....probably not the headlight harness. It's replaceable. Good luck.

[@gladiatortruckreviews]

Love the way the lights look in your video. I have mine installed. Fuse tapped into fuse 66. All connected the way they should be. When I turn my right signal and left signal they work as amber. But the lower portion won’t light up as a clear LED like yours does in the video. Any insight ?

[@MKSPerformanceOffroad]

Did you get this figured out?

[@mauriceartiles3968]

I just got my Alpha Rex Nova headlights and everything works other than the activation light where it has the sequential patter when u unlock the truck. Just the pod lights turn on. Then I have a „parking light out“. I did not install the DRLs just wondering if u had this issue or anyone have this issue

[@rosegold_21o85]

When I installed mine the lowbeams turn off when turning on the high beams. Why don’t they both turn on when Turning on the high beams??

[@MKSPerformanceOffroad]

They should unless thats a new thing they have going on which Im not aware of. My lows stay on with high beam. Have you reached out to alpharex? Are your lights wired correctly according to manufacture instructions and have you checked to ensure you have power where it should be?

[@chamomusic85]

The running lights bulbs can be replaced after it burns? Or do I need to buy new headlights?

[@MKSPerformanceOffroad]

The led strips are integral to the light just as they are from the factory so you would need to buy new assemblies.

[@MKSPerformanceOffroad]

Anything other than halogen will likely throw a code, however, you may want to look at hid as an option for low beams. Hid is suppose to mimic a halogen light source best according to the research I have found from various companies.

Does the yellow wire come from the headlight? Are these alpharex pro series housings or another series?

[@brianpemberton1151]

MKS Performance & Offroad it comes from the DRL harness box . Their website says to disregard that wire.

[@07THE19]

Installed mine the other day with Leds and am not happy with the light output whatsoever. I’m planning installing HIds, are these what you installed and what make and model if you don’t mind please.

[@MKSPerformanceOffroad]

I installed these with hikari 2020 H7 Led bulbs bought off amazon because the hikari ultras were backordered. Im happy with the ones I installed and adjusted them up a bit. You may have to play with different brands of bulbs and find one that best mimics a halogen. Some HIDs do this well from what Ive seen but I wouldnt put the HID in the high beam.

[@masonmer000]

If my ram already has DRL on the stock headlights will I still need to run the DRL harness?

[@MKSPerformanceOffroad]

I believe you do if you want the lights to work the way alpharex explains it for having the lights on as drl all the time rather than when your light switch is turned on. Once you Key on the lights wont light up until you turn headlights on if I remember correctly.

[@richardtapia8261]

What kind of fuse did u buy for the fuse tap?

[@MKSPerformanceOffroad]

I want to say it was an ATR, I would take a fuse out and take it down to match at local parts store, then order fuse tap off amazon like these but Im pretty sure it was an atr. amzn.to/3L5fNbt

[@richardtapia8261]

Thank you but I completely skipped over the wires because I bought a pair Luxx series from alpha Rex and I’m guessing on their new lights they sell they come with the fuse tap and the extra fuse needed all ready to go and attached ready to just put it on

[@edwardlance2379]

My son and I put a set of these on his 2014 Ram last week. We replaced the halogen bulbs with LEDs. We tried different bulbs, tried clocking them, etc. They absolutely suck with LEDs. Horrible, horrible beam pattern no matter the brand of bulb or how we clocked them. Trying some HIDs next. If those don't work, the housings are getting pulled and returned or sold. Shame, they look nice and the cool flash sequence when the lights are turned on and blinker is nice, but useless if they can't run bright lights. The basic H7 halogens are horrible.

[@MKSPerformanceOffroad]

The HID should do better as they mimic a halogen light source better than led and the housings are designed for a halogen light source. If a perfect led beam is what you are looking for then the best way to obtain that would be to buy the led version that alpharex makes. I didnt try these with the hid bulbs as I didnt want to stuff ballasts in and all that stuff but they are decent and better than the halogens that were in them.

[@edwardlance2379]

@@MKSPerformanceOffroad Yeah, the only problem with the LED versions from Alpharex is the price, stupidly expensive. We'll try the HIDs and see. If those don't work well either, then we're going to return or sell the housings and he'll just have to fork over the money for a properly made set if he wants it done right. I can certainly see why these LED bulbs in halogen housings are illegal for road use, they just don't work. My 2018 Silverado LTZ has factory LEDs and they work great, so I thought maybe the bulb they use would be good...but, I found out, factory LEDs don't use a removable bulb! If one burns out or quits, you literally have to replace the entire housing as the bulbs are built in..at $1,000 each!

[@edwardlance2379]

@@MKSPerformanceOffroad So we put 55w HIDs in the low beams today. They definitely do better, at least better than halogens and LEDs but still not what I'd call great. Now the question is the high beams. The halogens ain't going to cut it. We put LED's in and it's a joke, like the low beams. So, we're done screwing with this crap. The LED's we currently have are returnable, so they're going back and he's going to sell the housings and HIDs (someone will buy them), but at a loss, of course. He's just going to do what I told him to do from the get go...go pay the money and get the LUXX models. Plug'em in and be done with it.

[@MKSPerformanceOffroad]

@@edwardlance2379 I think you will be happy with the LUXX lights, LED is tricky sometimes especially with non led housings. Good luck with your build.

Nice vid man. If I were to install these headlights alongside a grill with marker lights, would I have to tap the into the red wire that runs to the fuse box? I want to have the marker lights run with the daytime running lights. Any info would help, I’m not exactly an expert on wiring hahaha. Also, is there any way to bypass soldering?

[@MKSPerformanceOffroad]

You should be able to tap into the red fused wire that goes to the fuse tap as long as it goes to a fuse that gets ignition power. If you want to avoid soldering than you can certainly use heat shrink crimp connectors or even heat shrink solder butt connectors that you insert wires and heat up then it melts the solder automatically fusing the wires in place.

How did the lights compare to the quads you replaced ? Which bulbs did you decide to go with ? I’m about to buy a set . Debating on the pro series like you have or the Luxx Series. Thanks

[@MKSPerformanceOffroad]

In my opinion they are alot better than stock quads. I went with some Hikari led H7 bulbs I will have them listed in the video releasing tomorrow evening for programming these. I did not get the hikari ultra bulbs as they were out of stock on amazon but for the cost of some ultra led bulbs from headlight revolution I spent half the cost on 2 pairs (high and low beam). Of coarse you can run halogen H7 bulbs in the housings and I felt like the light output was still better than factory. I enjoy the switchbacks and love the look as well. Hope this helps and happy modding.

Without the drl harness connected you will only have the led switchbacks light up when the headlights are turned on or you activate a turn signal.

Another question for the DRL , since I’m unable to get a hold of alpha Rex. Are the red wires hot on your harness when the key is off . I’ve got my harness wired up correctly . But the red wires that hook to the light for DRL stay hot. I’m not sure if the harness they have has a timer or not . But either my harness is bad or I don’t understand how that harness should actually work. Basically my key off grey wire is cold , DRL remains on . Thanks for any help

[@MKSPerformanceOffroad]

How long do the DRLs stay on? If its more than a few seconds After you lock the truck like say they are on for a min or so then it is possible you have the DRL wire powered off a fuse that is always hot rather than ignition. Do you have instagram?

MKS Performance & Offroad , no Instagram , yeah that’s why I’m curious how the harness should work . My grey wire is cold key off . I confirmed with light tester.

I always just go back with OEM headlights, I never really understand the fascination with these tricked out aftermarket headlights. I see guys with these on the road and they may look good for a couple weeks or two, then one of the bulbs burns out or something starts blinking or it just doesn’t look like the same light output on both sides.These things cost outrageous amounts of money, and seem to last about two months before having issues.

@@kevinseely6632 depends on the brand and options you choose, your right that they do cost a good amount but in most cases they are not as much as an oem light that could potentially have the same issue.

The gap is not even near 1”, the most gap I have is from the filler panel underneath the headlight to the bottom of headlight but it is still not bad. I like the look of these and yes you can get headlights that are much more expensive like factory or morimoto that may have a slightly better fit but will and do function exactly the same. I wouldnt discount Alpharex or any other light manufacturer simply because the gap between light and body panel is slightly more or about the same as factory.
