Light Bars & LED Lighting in Kentucky
Kentucky sets no lamp-count or candlepower cap and requires no cover — but it prohibits retrofit headlamp covers and films that change the color of emitted light, so a tinted cover is itself a violation. Front-visible light must be white or amber unless it is original equipment, and blue is prohibited.

What the law says
Like Illinois, Kentucky is a state where the common 'just cover it' advice describes an offense rather than a compliance step. Note: covering the lamp is not the compliance route here — smoked or tinted lens covers are themselves prohibited. 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.
