Typically these are as easy as pulling out a connector, a clip, a harness clip and yanking the bulb out. Owners manual should say specifically the process.dito the HID.
also, how easy is it to change the bulbs on the 1500? Mine is on order and should be here this weekend. So I haven't looked at the headlight assembly yet.
My 2500 was ok to change the bulbs with the right tools.
