Needed new headlights on my 2014 Cruze because my passenger side headlight was broken, the 2 bottom screw mounts broke off so it was no longer secured at the bottom, the headlight could no longer be adjusted so it always aimed low and my driver side started to leak into the signal bulb section of the housing so it would get water inside. I wanted headlights that not only looked nice but were also an upgrade in performance from the factory headlights.These install and fit exactly like the factory headlights although you have to wire in the DRL halo lights and DRL LED lights along the bottom of them, these also do not use the original low/high beam H13 bulbs the Chevy Cruze uses, these housings instead use 2 separate bulbs for low and high beam, they run an H7 for the headlight low beam and an H1 for the high beams. These arrived with the H7 and H1 halogen bulbs already installed in them, so unless you want to upgrade from the halogen bulbs to LED's you shouldn't have to purchase bulbs for these they come already installed in them.Wiring in the DRL's isn't to difficult if you already know how but if you don't Spyder Auto has a FAQ video on their YouTube channel for installing LED accessory lights and CCFL lights. You will need a volt meter with power probes to determine what wires you need to splice into if you decide to wire the DRL's into the factory headlight harness of your car (most Chevy Cruze have a factory DRL in them so wire into the headlight connector harness, Spyder Auto will tell you in that FAQ video to wire into the parking light wire of the signal bulb connector but this doesn't apply to the Chevy Cruze the DRL,s run through the headlight not the signals) you can wire directly into the headlight housing harness that comes with these headlight housings which is easier thats what I did. Splice the green and red wires on the headlight housing together for power and both of the black wires together for ground then splice them into the headlight assembly harness that comes with the housings, black/black to the black wire of the housing harness for ground and the red/green to the blue wire of the housing harness for power (the red wire in the housing harness is for the high beams)The quality of this headlight assembly is really good for aftermarket in my opinion, you get both the left and right headlight housings, they're sealed very well, the connectors fit to the factory headlight connectors (the factory signal connector and bulb on the car will need to be used they do not come with these but they fit directly into these) and they fit just like the factory headlight assemblies do, no modifications were needed except for wiring in the DRL lights. They do not come with new screws so you will need to use the factory screws that mount the factory headlight housings. The headlight adjustments for these are an 8mm. socket and both the high beam and low beam can be adjusted both left/right and up/down which is marked on the housings and very easy to understand which direction they turn to adjust while the factory housings can only be adjusted up/down and don't specify which direction the adjuster is turned to make the adjustments
