Don't buy them if you have a 2014 GMC they do not fit, they will only fit a 15 to 18. I'd leave a 0 star if I could because they won't refund or respond back
Headlights are super bright and installation is straight forward. They do add an additional harness for day light running lights that make it more complicated but ive opted to just do the basic install. Worst part of the headlights is the adjustments are all on the back so you will remove and reinstall these alot to get the aim correct.
I read a review that said the customers lights worked for 3 months before they had a problem. My started right after installation. They returned a fault inside the vehicle that the right tail lamp was out even though the lights were all on. Beeps every few minutes to tell me I have a light out. Very annoying! Alpharex sent out a replacement but, if I had known better I would’ve avoided the aggravation entirely. Don’t do it!
I'm really happy with my pro series purchase. I'm definitely going to upgrade to the luxx series but the Craftsmanship is hands down the best! Install is really easy. And just the packaging it comes in tells you that it's something special.
