Spyder Signature GMC Sierra 1500/2500/3500 99-06 / GMC Sierra Denali 02-07 / GMC Yukon 00-06 / G

looks and works great, ended up soldering mine in, do not like quick connects, so the install took me a little longer. The only thing I did not like was where the up and down adjust was located, had to keep removing the headlight to adjust it, but it's not a big deal. once its set, its set. It is 100% better than the oem denali headlights I had bought, and had installed in my 05 Yukon. I hated the operation of the oem headlights, liked how they looked. I should have just installed these to begin with. Only question is, is that can the halo's and led's be hooked up to the DRL's instead of the parking lights? All the install instructions I found said to hook them up to the parking lights. Just makes more sense to me to have the halo's on when your headlights are not on. I don't usually drive around with just the parking lights on. Only change I made was to or some better lamps. the low beams it comes with are really yellowish. I ordered some Phillips diamond vision 5000k lamps for it, I did not want to go HID. hopefully they work out great. all in all, very happy with the purchase. looks great on my Yukon, and work great too. update: don't get the Phillips diamond vision 5000k lamps, they suck, look white when looking at them, but on the road at night, they cast a blue hue and you cant see as well. ended up using a razor blade and scraping off the blue coating.

Updating my review: These are great! I have an old 2001 Yukon and with the stock headlights you really cannot see to drive it at night. I looked for something to improve that and ordered this product, after researching things. These work great. Even with the stock H1 bulbs that comes with the fixture. This really makes a 100% improvement. You can actually see to drive at night. Next, I may upgrade to LED bulbs, down the road. But again, even with the bulbs that came with it, it makes an incredible different on this old vehicle. Additional note: These really do just swap out. Pull out the 2 rods that hold the old fixture in, remove the old 9005 Hi-beam bulb from the old fixture and then insert these new ones in. These come with an H1 low beam bulb, but you will need a 9005 hi-beam bulb to put in it. Took less than 5 minutes to do both. There are numerous wires, but you do not have to use them, if you are just wanting high and low beam headlights, just swap out the fixtures and that's it. If you want the extra stuff like the halo lights, turn signal or parking lights, then you will have to wire those in.

The headlights look awesome and are very heavy and appear to be good quality. My problem with them is they didn't fit on the first try. They are larger than OEM lights around the edges and because of this I had to use my dremel to shave off edges so the mounting pin holes would line up. Otherwise the edge of the light pushed on the fender and pushed the light out of alignment. I also found the mounting pin bracket closer to the radiator was not seating properly and I had to shave that down as well to make the unit fit with the factory pins. I did this so that all my gaps would be even on the lights. The first time I mounted them the bottom of the light had a huge gap and protruded from the truck because the pins were not seating into the lower mounting holes due to the poor fitment at the edges and brackets. Be sure to take off the fan shroud while installing these because it makes seeing the brackets and where they are catching a lot easier so you know where to trim. I'm still working on wiring the halos and LEDs, if I find any problems there I'll update this review.

I know i got an extremely good deal on these halo lights from amazon.com. They even came with instructions. Also u can go online to see how to put them in. Once you go halo it will be hard to go back to stock. Besides, most of the time, when u have a vehicle from 2002 like i have, they are gonna make something better when it comes to parts so i might as well have upgraded. They look really really good, but i like the look better when the rings are the only lights lit. These lights can run u 400 bucks, shop around be patient its worth it. For a while it took me a few minutes to understand what all the wires were operating, also i never used the new wire connectors before until today, and they made the installation that much easier. Total installation took about an hour but if including time it took me to figure out what the wires were for , it can take an hour and ten minutes. I own a gmc yukon xl 2002 model. When u get to wiring the LED's(white and black) and Halo ring(red and black) the Blue wire is the flasher(on the parking lightbulb), and the dark brown wire is the continuous power wire(middle wire on the bulb). The black wire on the bulb is the negative. I will post Pics. BTW so far im the only one in my area that ive seen with them, so yes yes yes yes. ok Im done

Build quality: These headlights look nice but the plastic is thinner than the original lights. The lense is thin but workable as these don't vibrate while driving on paved roads. Haven't driven offroad yet. The halos are dim and uneven. The bulb is on the lower side and the halo dims towards the top. I don't care for them and won't be connecting them. Installation: GM makes headlight installations very easy. However these lights are difficult to align with the rod holes. Adjustment: You must remove these headlights completely to adjust them. Doable but takes time and patience. The Up and Down marking is wrong. It is opposite from what is marked. The Left and Right is correct. Operation with Halogen Bulbs: These lights are pretty good. The hotspot is where it's supposed to be at the corner of the slant and there is good little dispersement to either side. These lights are adequate with halogen bulbs; however I'd recommend using some Philips CrystalVision. Operation with HIDs: With some 35W Kensun 5000k HIDs, everything becomes brighter. There is no change to the beam pattern or area of light concentration. I can't see any vibration however Verdict: These are nice but I will be running these with HIDs without the halos.

Great headlights, they look very nice. Easy to install. Ony thing, that could be done better is, the adjusters for the light could be in a way better spot where you can actually access them, instead of having to remove the light make your adjustments and reinstall. That gets very annoying very quickly. Other then that lights are nice looking and have made a big difference in about of light that comes from my truck now. I would recommend these lights, despite the adjustment issue.

La entrega se retrasó unos dias, pero llego en perfecto estado.

Good fitment. Will need to be aimed ,which is a bit of a pain. Will accept hid. And projects a good light pattern. Not blinding to other's. High beam pattern a bit off. But rarely use them having hid in low beam. Over all a good product.

Easy to install, look and work great with HID's, Easy to adjust and aim the beams where you would like, nice cut off line.. Haven't wired in the halo rings or LED's at the moment yet.

Great light, look great too, big improvement. Some wiring needed, I installed it using a relay switched by ignition, worked beautifully. But you should know what you’re doing electrically.
