There are liability issues that may arise if lights are absent or insufficient. The two articles below discuss some of those issues. 

Although this Wikipedia entry does not focus on New Hampshire law, it does provide background information, giving an interesting and detailed discussion of many aspects of automotive lighting from an international perspective.  Topics discussed include history, color of lighting, forward illumination, conspicuity, signal and identification lights (front, lateral, rear, large vehicles, emergency vehicles, retroreflectors, experimental systems and research and development), convenience lights, on service vehicles, many footnote references, many photos, and external links.
