The bulbs are nice but for my 2018 ram 2500 cummins they threw parking light out codes. They did come with resistors for the turn. I went to local parts store bought more resistors added them to parking light wire. The codes are off for now. Just hope those resistors dont get over heated. So 4 resistors for one set of bulbs on 2018

Love the way it turns out

In my previous review of the low beams, I noted that I did not do the high beams, and turn signals - a mistake that I did not repeat.

This install will seem a bit daunting if you do not watch their install video and attempt to skip using a multi meter to ensure that you have the positive wires for the turn signal (the parking/running light has a seperate wire). I'm certain there are differences in the individual RAMs, but you should expect to see 11.59+ volts as the blinkers are working.

Over all, install is very simple if you get the correct tools. I suggest using the Irwin Self-Adjusting Wire Strippers that allow you to strip the middle of the wire (like you see in the video), and instead of using the supplied wire connectors solder the connection as they do in the video as well. An additional step that I did was to apply diaelectic grease to the splices after soldering, and then sealed them with heat shrink. Take the resistor mounting advice given in the install video, and everything will come back together just like factory.

I did have a problem with the bulbs, but Caleb at Headlight Revolution was right on it, and had replacement bulbs to my door in short order - much quicker than I anticipated. The new bulbs are flawless so far.

Performance, like the rest of their lights is superb. Differences between these bulbs and halogens is dramatic, and the addition of the switch back provides an extra light source when the blinkers are not on - a thing needed after hurricane Michael where we still have less than 20% of street lights working as of this writing.

Overall, this is a fantastic product that has been well thought out by HR, and I just cannot say enough about how great Caleb has been helping me sort out the issue with defective bulbs.

The man deserves a beer!!!

The kit I got is awesome

It been my experience that like others have said they are not a quality product I had them installed which cot me extra money and then they didn't work turn the turn signal on and a code came up blown turn signal and the wouldn't even light up and when the park lights was on and you turn the turn signal on it throws a code of blown marker light so in my opinion they are not worth spending money on especially if you have to pay someone else to install them

Instead of addressing the issue you all at Headlight Revolution would rather just delete my review . Ill never do business here again! You claim to stand by your products but in the end you all dont.

Cool look, easy to install, work well

I ordered these a few weeks ago, they seem ok haven't installed them yet. My only concern is why did I receive the older style instead of the newer ones? The ones I received dont seem like they're worth $90 looks like something I could've got from Auto Zone for $20.

Rather easy to remove the headlight assemblies. Oddly enough on a 2016 Cummins the turn signals do not hyperflash and I hadnÄôt installed the resistor yet. Will keep on hand but this particular application seemed to be truly plug n play! CanÄôt ask for anything more than that! THEYRE BRIGHT!!

The product looks got, but doesn't look like it's worth $90. When I ordered I thought I would receive the new design. Other than that I'm waiting to install because the V.4 headlights are on back order. I want to install everything at once. Saving time from removing the grill twice.
