Do your factory GMC headlight come with Autosystems on the back of them or so they say GM all over them?

I just bought some from someone telling me they were factory GMC headlights and when I get them today they have Autosystems all over them.

Someone look for me please

didn't remove the headlamp to look, but, the front of the headlight says "GM" blah, blah, blah on the clear plastic part on the bottom

Do you know if there is more that one adjustment on there?

And is the back chrome if you rememeber?

Do you plug straight into the back of the lamp or into an adapter?

Thanks man,

I thought I had gotten ripped off. The regular Sierra ones say GM all over everything thats why it set off a red light.
