There is a link that applies to trailers from the National Highway Transportation Safety Administration. The light laws for motor vehicles are the same I just can't find you a similar table. Look near the bottom of the chart for the laws that effect the hummer...

So yes the H2s are required to have marker and clearence lights.

You were close...I found them on the same site, different page.

Looks like 2, 6 and 7 would apply to H2s.
