Can anyone point me to a document/site where I can determine if the cab/marker lights on the top of H2s are 'required' to be 'street legal?' People say they are...and obviously GM puts them on every H2...but I'd really like to see it in writing.

I've tried to do my own research....I've spent the last hour Googling federal vehicle standards and can't find anything about what vehicles are required to have cab/marker lights.

Thanks in advance...and I live in Maryland (in the event that 'state and local laws may apply'). Googling that didn't help my search either.
