I now love everything about my 2015 Denali 2500 HD! At least now that I have headlights that will actually allow me to see at night! I decided on the Morimoto Elite kit with the XB55 computer and XB 5500K lamps. Installation was simple and took right around 1.5 hours including the installation of LED fog lights.



It is easy to see that this kit consist of quality hardware. All wiring is contained in black heavy duty wire loom which not only offers protection but makes for a much nicer and neat installation which totally blends in to your engine compartment. All plugs are high quality with waterproof connectors. Everything you need for installation is included with the exception of wire ties and screws. This kit matches perfectly with the LED daytime running lights and the XB LED fog lamps.



For the record I have read through a couple of forums where people had issues with the lamps shining to the right side of the vehicle. During installation pay special attention to the position that the bulbs lock in to the sockets. When locked in to place the wires on the lamps will be facing down. Attempting to install them in any other position will result in poor beam dispersion.

Did some research and knew this was the kit, after failed attempts on prior vehicles with DDM and other cheap kits. This is a great kit, but the harness to the opposite side should be at least a foot longer to mount it properly. It is really stupid how GM put an air box screw under an A/c line too, I took apart the front end since I was also replaced the grille, I removed the headlights, installed the kit and re-installed them. The color matches the LED's on the SLT and the light output is a lot better. stock projector high beam illuminates on top of you and not ahead of you. Next project maybe........

Installed the Morimoto-elite-hid-system on my 2015 Sierra this weekend. WOW, I can now see at night. Prior to this, it was like driving at night with no lights on. Installation was fairly easy. Only difficult part was removal of air filter box and drilling of headlamp covers. I highly recommend this product to all GMC Sierra owners who want to see at night while driving.

Stock halogen lights on the '15 Sierra Denali are junk - barely adequate for driving in the parking lot. This HID kit fits perfectly. Ran the passenger-side wiring under the plastic shroud and mounted all the hardware to the front bulkhead with self-tapping screws. The only visible hardware is some wiring between the underhood fuse box and the driver side headlamp housing. Unless you were really looking for it, the system looks nearly stock! I've been running this kit with the TRS custom-fit LED fog lights for about a year now and it's been completely trouble-free, even through the winter in MN.

I ordered the 35w set for my 2015 GMC 2500. I had a 2017 gmc with the new gm lights and they were great, I traded down for a bigger truck and wanted to match the lights the 17 had. The setup was fairly easy and took an hour or so to do. I was not happy with the light output so I returned the 35w for the 50w. I would recommend the 50w for the noticeable light output differance. My only complaint is there is a buzzing from one of the ballasts, the 35w did not do that but trs says that is normal. So far so good.

This review is for the 35w ballast and the 4500k lights on a 2015 GMC Sierra. The light output from the 4500k bulb is considerably whiter than the factory halogens and EXTREMELY bright. I understand that the projector sends the light beam in the same patter as the factory lights, but since they are so bright you definitely feel like the patter is wider since everything in front of you gets lit up. I did re-aim the beams down a bit because several people flashed their high beams at me. I feel safe driving at night now, especially in the rain.



The overall installation was fairly easy. They include an extension that goes from the relay to the driver side ballast but I didn't need it. If you take your time there are plenty of ways to tuck everything away neatly. My only complaint would be the wires coming off of the light bulb that go to the igniter are very short and it really limits your mounting options for the igniter. It would be nice if they were a few inches longer.



The quality of the product seems excellent, as is the customer service and you get peace of mind with a 5 year warranty. Shame on GM for putting such crap on a great truck, KUDOS to TRS for correcting their screw up!

I have a 2014 GMC Sierra with the horrible projector lights. I finally got around to ordering and installing this upgrade. Install was pretty smooth and I will know more tonight after I try them in the dark but can tell a world of difference just aiming them at the wall. The Retrofit Source was great to deal with and answered all my questions. Highly recommend this for 2014 and 15 GMC Sierra projector light suffers.

I've owned anything from xentec, XKGLOW, OPT7, Hikari, to no name Amazon/ebay brand kits. I always thought they were all great. Always said why waist 150+ bucks on others when cheaper brands were fine. I was wrong. SO wrong. I swear I'll never cheap out on my lights again. This was worth every penny. I don't even write reviews on anything. But I had to take a minute of my time and just help you all reading the reviews. Just do it. Simple as that. You don't even need the 55w kit I should have done the 35w because it's legit almost too bright to where I feel bad. Save your money and get off Amazon and just get a morimoto kit. If you could "like" a review you would come back and like this post and write your own.

I did however experience a small problem. And I don't even care I'll still give 5 star. I couldn't use the wire that's connected to the HID bulb that goes into the stock bulb housing. I had to run direct from relay harness right to stock connection and then it worked. Don't even care... The results are insane.

I have been buying lights from TRS for years now. The quality of the product is undeniable and the customer support is second to none. Thanks for lighting my 12 O'Clock.

Purchased these in the 5000k setup for our denali sierra and I have to say WOW. Night and Day difference. GREAT kit! Truck now looks like what a denali should.
