What is your question?
My cargo lights won't come on my 2008 GMC Sierra 2500 HD and wondering if they are supposed to come on or when should they come on

FROM OWNERS MANUAL: Cargo Lamp The cargo lamps come on by turning the instrument panel brightness control knob to the farthest clockwise position. This knob is located on the instrument panel and also turns on the dome lamps. The cargo lamp can be used if more light is needed in the cargo area of the vehicle or in the top-box storage units.
Now 'IF' that don't work let me know - there's another possibility why.
