What the law says
Because only one auxiliary driving lamp is permitted, a multi-lamp bar generally falls outside the allowed category. Contrary to widely repeated advice, no cover is required in this state. Mounting a light bar is legal everywhere; what states regulate is using it on public roads, and the usual constraint is a mounting-height ceiling plus a per-type lamp count — a roof-mounted bar often falls outside the permitted category entirely.
