SPEC-D TUNING Blk Smk LED Halo Headlights For 2001-2006 GMC Yukon, 1 Set

These aftermarket lights fit right in and the wiring directions were easy to understand and install. How they updated the look of my twenty year old truck made it look like a retro modified vehicle. Very nice product and the price is great. I changed my Yukon to Denali style headlamps and the drop right in. The 'halo' part wires to your fog lamps, so you lose the fog lamp's operation via the switch. In my case, I am going with aftermarket LED's and another toggle switch. They look great. Super bright.

Comes with easy instructions to wire up the led portion of the lights. Bulbs included

This is my 2nd set of Spec D headlights. I bought a pair for my 2001 Lexus GS300 that I loved. I bought these for my 2005 GMC Denali pick up. Installation was a breeze it snapped right onto the factory holes and mounts with no problem. These are a little less bulky than the factory but they look good and the little features like the signal light strobing when the headlights are on was a nice touch.

Does not use factory style bulbs. Plastic is thin and soft. Fitment is close, but not exactly. The high beam back cover gets in the way of the mounting pins. The covers are rubber and will move out of the way, but it does get in the way making it more difficult to install. The LED accent lights need to be wired in and do not just plug in directly. The connections given to wire them in are garbage and will damage the wiring. I don't recommend using them. Especially if you live in a salt belt area. The light emission from the lights is really good. The plastic gets really hot. I see the potential of the plastic melting as it's not abs plastic. The replacement marker bulbs will need to be the natural amber bulbs as the lenses are clear. All new bulbs are included except for the daytime running lights. They look good and function pretty well, but there is a lot of room for quality improvement. For the price, they're decent. I don't expect to get the 20+ years out of these replacements that I got out of the factory lights. The plastic is too soft to have the same durability as original equipment. Also, with the softer plastic, I expect to experience warpage allowing moisture into the casing. Suggestions to the manufacturer would be using the factory bulbs, abs plastic and better fitment, and giving adapter plugs to wire in the LEDs. Other than those issues, they're a pretty good light.

Just installed mine today. They are absolutely beautiful and bad a$$. I would have given them 5 stars, but what a pain in the posterior to adjust. You have to pull them out, guess at which screw to turn and which direction, and then reinstall, and then repeat, over and over. The directions were not very helpful. My first time installing headlights like these. Fortunately if you go to their website they have enough instalation info you can piece together what to do with the extra wires. But like I said, they look awesome and work great. I would have given them 5 stars if the headlights came with better directions and if it was easier to adjust them.

Got these to replace the ones I got back in 2013. Over time they yellowed after sitting in Phoenix 10 mos out of the year!! Paired them up with a set of 6k Xenons and the light output is great! Make sure you adjust them especially if your SUV/Truck is lifted so you don’t blind others! Will definitely get another set once these fade in another 10 years!!

Product is very very cheap, has a thin plastic housing (The OEM has metal housing). This is poorly built and you CAN NOT use your stock bulbs with this housing unit. You have to use their proprietary bulbs that come with the unit, in order for it to even work. They say you can get a conversion kit to use LED lights, but that will blow a fuse everytime you turn on the headlights. Also you will have to splice wires in order to get the Halos or the side LEDs to work. This product should not be sold as a being compatible with the yukon denali, the turn signal light will not snap into place and will come out at some point as you ride down the road. Very cheap and cost cutting. This unit is probably the worst unit you can possibly purchase. For a cheaper price I would even get JSBOYAT 4pcs Projector LED Halo Headlight Assembly Fit for 2001-2006 GMC Yukon Denali. BUYER BEWARE!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!! Told them after I opened it and looked at the proprietary bulbs and housing that I would like a refund, they told me it was past the 30 day return. They know this item is cheaply made so they hope you will keep it past the 30 days.

We really like these lights, just had to figure out the wiring and all.
