Carrier Enforcement officers of the Commercial Vehicle Enforcement Division (CVED) who enforce truck safety laws, drive vehicles identical to regular MSP patrol vehicles, except that they have a "Commercial Vehicle Enforcement" designation on the rear quarter panels of the unit in gold lettering. CVED currently uses only the Chevrolet Tahoe. Starting in 2008, CVED moved to the Tahoe platform and began using the same paint scheme as the Troopers' vehicle. The words "Commercial Vehicle Enforcement" were added to the quarter panels and the 'Motor Carrier Enforcement' decals on the rear were replaced with standard "State Police" decals. Unique lighting Fully marked patrol vehicles feature a single red overhead light, the RV-26 or RV-46 "Spitfire" made by Unity Manufacturing that rotates when activated; however, in late 2009, MSP announced that these are being retrofitted with red LED lamps rather than incandescent beams to reduce the hassle and expense of replacing the PAR 36 or PAR 46, 60,000 CP sealed beam bulbs and servicing the rotor motors. Red lenses on some MSP vehicle roof beacons have one or two clear horizontal stripes that allow some white light to shine through, giving the lamps a pinkish glow at long distances. Michigan State Police have continued to use the "gumball" style lights instead of lightbars as they are unique, reduce wind drag, and are highly visible at long distances. (New Jersey State Police as part of there 100 year anniversary. Some Vehicles using the 1940's livery use the same lightbar that the MSP uses) MSP vehicles also feature a clear plastic sign, referred to as a "hood light" or "hailer" or "shark fin" on the hood that lights up when activated. The historical use of this hood light dates from the time when a "side stop" patrol stop would be initiated by pulling up next to an offender and the Trooper would motion them to pull over in daylight; at night the hood light was illuminated displaying the words "State Police" and "STOP" (MSP no longer use the "side stop"). Patrol units also use red and blue LEDs facing to the rear of the vehicle and in some forward facing push bumpers, as well as headlight and tail light flashers. Both the rotating overhead light and the hood light have traditionally been synonymous with the MSP. The rotating red light has been used by the MSP since the 1950's and the current style red
