Where to start? I ordered headlights from this company. needless to say, i contacted them, notifying them of the problems with wiring. asked them for some sort of instructions, and it comes with zero. "They sent a retro fit from a completely different vehicle a YouTube video for chev.. i knew it was wrong, and they still sent this crap, assured me its a vehicle prob. its a plug and play set. well i plugged and played it, and it cost me over 300 to fix the problems, not to say 3 days to get the parts to my vehicle. that this specific set advertised specially for my vehicle. do not i repeat do not purchase these for gm. i will never ever purchase from m auto again lying theives. unwilling to work with my problems or refund. i learned my lesson from these incompetent people, and will direct eveyone to stay away from m auto. ive posted and blasted across all platforms. which i wouldnt have done had they tried to fix the prob. or offer solutions. nothing. heres your review. the headlights are cheap the seal i didn't get to see prob would have lasted a day considering the front lens that was mounted to the assbley had gaps for moisture, the wiring will fry your whole system and js pretty lame. and youll be left with no response and repairs you will have to make on your own. i did it all myself. 297 for all fuses relays and electronics it ruins. twice what they cost me and im still sitting here with my old lights that work now. 300 spent to fix their problem. any way i hope this helps. its been one month ive emailed thats the only source you have. and nothing.
