Light Bars & LED Lighting in Alabama
Alabama allows auxiliary lamps on the road — no cover is required and they need not be switched off — but only one auxiliary driving lamp (mounted 16 to 42 inches), two fog lamps, and one spot lamp are permitted, and anything over 300 candlepower must be aimed so no part of the beam strikes the road beyond 75 feet.

What the law says
Alabama permits just one auxiliary driving lamp, so a multi-lamp light bar generally falls outside the permitted category regardless of covering. No red may show to the front. 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.
