I give this pair of Spyder® brand fog lights a 5 star rating in appearance and performance. Installation took about an hour (if only because the old/original equipment fog lights on my 2004 GMC Sierra 2500HD truck refused to come out without a fight). These Spyder® replacement fog lights are a near perfect fit for my truck. One thing though, my opinion is that the "halo ring" is an afterthought on these Spyder® fog lights. The halo effect is not too bright and or impressive. But this minor detail does not take too much away from the overall appearance, brightness, and quality of these Spyder® fog lights. For one thing, you can choose to not even connect the “halo ring” or you can also connect it directly to the daytime running lights (that way the “halo ring” will be on whenever the truck is running). I think these fog lights look awesome on my truck; a great improvement to the look of the front of my GMC Sierra. Great fog lights overall. One last thing, the wiring harness is included in the package; this includes switch, relay, and enough cable to reach wherever you decide to place the switch. I did not have to use the wiring harness because my truck was bought with factory installed fog lights and I merely had to “plug in” the new Spyder® fog lights. I hope this helps you decide.
