I have a 2019 Blazer premier that I inherited from my Father this past summer. I didn't realize the headlights were so poor until winter and it was darker sooner. They are HID. What year and lights do you have? I went to a dealer and they put mine and another 19 next to each other on a garage door at dealer and said they were aimed properly. They said if they adjust up to see further the high beams would point at the sky. I am frustrated and looking for ways to replace with something brighter. I asked a local custom auto lighting shop via text and phone about the bi led projectors and he said its not the hid but the housing and pointed me to ebay for a 19-20 housing. why would I put the same housing in? Could you dm me for advise on what you have done. It appears buying the projectors is the way to go as you have done.
