Spyder Auto PRO-YD-CDE00-HL-C GMC Sierra 1500/2500/3500/GMC Sierra Denali Chrome Halo LED Projector Headlight with Replaceable LEDs

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 howeverVerdict: These are nice but I will be running these with HIDs without the halos.

I thought I wrote a review to this and posted pictures earlier, but I guess I did not. I like the lights they work very very well. My issue with these lights is that the halos around the lights are not noticeably bright enough during the daylight hours. I would love to have them lit, bright enough as daytime running lights. During the night they look very good for during the day at a distance, they can barely be seen. My other issue is that the bright lights are not good! Usually regulates the beams are beautiful cover a lot of area and you can see further down the road which is very enjoyable for night driving. The bright lights are not good at all the regular beams work better than the bright lights does. When switching to the bright beams, the lights seem to go a bit further, but the Intensity in the beam direction is not a good quality. If you do not use your bright lights often and not concerned about the halo brightness then this is a good purchase. Don’t get me wrong. I do like the halos at night time you look very awesome and it even has the three LED blinkers on the side which you can connect to your blinkers, or you can connect them to your daytime running lights as I did along with the halos. you can be creative when connecting these lights to your vehicle

The installation video is complete crap. Also I was unaware that this did not come with the bumper lights so I had to buy them separately. (It was my fault for not making sure, however, every other halo light I’ve seen sells them as a pair). This should have been more clear IMO. The lights look sick though! Much brighter than my sunfaded oem’s.INSTALLATION:The red and white wires need to be connected to the running light’s hot wire. The running light is usually the middle bulb of the 3 bumper lights below the main high/low beam lights. If it’s not the middle light, it’s the one with 3 wires that plug into the bulb.. One with constant power, one ground wire, and one with pulsating power when you turn on the blinker to that side (you’ll need to test the wires by turning on the blinker and putting the black volt meter chord in the ground wire, then testing the other 2 wires with the red to see which is pulsating and which is constant) The middle wire of those three wires is typically the one with constant power. This is where you’ll splice the red and white wires. I used tap splices. Then the black ground wires will be spliced to the black ground wire of the running light.

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.

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.

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.

Direct Plug and Play. Excellent fit into factory clips. Very nice upgrade with very good light improvement over stock.Side note: Due to it being a projector style light it does protrude out slightly more than the factory light. Worth it for the added vision at night.

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.

Very well made product and looks amazing.very easy to install and wiring in halo lights couldn't be easier.
