Light Bars & LED Lighting in Michigan
Michigan is one of the few states that genuinely requires covers: any lamp not expressly required or permitted, and not meeting the federal lighting standard, must be both covered and unlit while on the highway.

What the law says
Front-visible lamps must show white or amber. Michigan is the state the 'covered and off' advice was actually written for. A cover is genuinely required on the highway 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.
