, we meant no offense - not all makes/models are updated in our information just yet, but we add more as that information becomes available. While you are right that there are no GMC, Chevy, or Cadillac listings in there just yet, some forum members probably own other types of vehicles as well, and we were just advertising that some of the information was now available.
When we have some more Equinox-specific information, we'll make an update here. In the mean time, if you're not sure of the bulb types to use, we would recommend checking with your Owner's Manual (or inspecting the currently installed bulbs). If you know that the 2018 model uses the same as the 2017s, you can also look at those listings too.
