Ok guys he is one for you. I look at the options label in the truck (on the back of the back of the spare cover). The code TT6 is on there (see photo attached). I pulled the right front head assembly out to change the cornering lamp bulb and see that I do not have HID head lights. I have a regular halogen blub. Is it possible that the previous owner changed it? Based on the fact the label states I have the HID lights, can I replace the Halogen bulbs with HID bulbs? The plug looks the same so I am courious if this can be done.
