Halogen Continuous
Present day models have aluminum chassis, polycarbonate lens, and mostly contain more than four rotating lights with additional takedown lights. Police light bars are fast replacing other types of emergency vehicle lights. Other forms of emergency lights like single beacons, dash lights, and deck lights are also used for emergency lighting but by and large police light bars appear to be the popular choice of law enforcement agencies.
The earliest forms of police lights bars were just metal bars fixed on top of the vehicles on which the concerned department mounted two rotating beacons with a stemmed bulb in between. But soon the manufacturing companies started producing complete police light bars, which were elongated domes that contained rotating beacons, reflectors, and beam lights in the center. With every new model there were modification in size, colors, flash patterns, capacity of the reflectors, and rotating ability of the bars.
Because of technological advance, police light bars are nowadays a perfect fusion of utility and aesthetics. Many of the newer models of light bars are in four rows and have deep corner pods. Owners can program the flash patterns in most of them. The lower rung of lamps in these police light bars consists of what are referred to as takedown lights, which can be disassembled easily. These lights are designed to focus fully on the vehicle that is being chased.
In earlier models of police light bars the siren was situated in the middle of the two beacons. Now sirens have been to a large extent displaced from within the light bars to the bumper so that the light bar dome has space for incorporating things like extra lights, mirrors, or light arrows for traffic control. Police light bars are variously V shaped; rectangular, or even come in the shape of dolphin, in aesthetically satisfying patterns. Chassis of present day light bars are made of aluminum, and lens is of impact resistant and highly transparent polycarbonate. Lights on the two ends of light bars are designed to light up the two sides of the road.
On an average, police light bars will have five numbers of rotating lights. Certain models have four numbers of bi-directional rotators. Light bars are now available in wide ranging standard configurations to meet everybody’s requirements. Besides that, manufacturers of light bars are always ready to customize these lights for whoever needs them. The lighting mechanism used in police light bars may be LED, strobe, or halogen.
There are online directories that give long lists of police light bars manufacturing companies. Each of these manufacturers provides complete product details together with graphics, making selection easy for customers. Besides the police, long distance vehicles like trucks, towing trucks, medical emergency vehicles, and construction vehicles use police light bars.

Is it possible to use US Standard 110V/60Hz monolights in the UK with a proper transformer?
And what kind of transformer would I need when each light needs 1200W?
Ive got a few Visatec Solo 1600 strobes that I brought over from the States, all are sadly US standard 110V/60Hz (as opposed to dual voltage). Since it was oodles of effort to get them here, I would really love to use them so Im trying to find a transformer to run them here in the UK. While I believe each needs 1200W, Im not sure they would need continuous 1200W as the only continuously running part is a halogen modeling light, but nonetheless, I would rather be safe than sorry. Has anyone had any experience running their US strobes in the UK? Any help would be huge!
Aside from the transformer, which is the easier and cheaper part of the problem, there are only two ways I know to convert the frequency from 50Hz (UK) to 60Hz (US): mechanically, using motors and generators; and electrically, using a rectifier and inverter.
A lot of times, companies will sell frequency converters that come with voltage transformers since if you’re wanting to change frequency, you’ll probably be wanting to change voltage, too.
As you can see (below), these can get pretty expensive…
If you’re a professional and don’t want to risk damaging this equipment, then you’d want to buy something that is manufactured to be on the safe side…otherwise, I’m sure you could just build one of these on your own for considerably less cost.
One thing I’d do is call up Visatec and ask them about these lights. A lot of times, devices will be pretty flexible as to what they can handle as electrical input, but since these are made in the US, they probably just slapped on some 120V/60Hz rating since those are the norm. Ask Visatec to get you some information on if these can handle a 50Hz signal. If all these are are lights, then it seems like there could be a good chance they’d accept 50Hz; if there’s a power supply and lots of equipment that goes with them, then I’m not so sure.
Here’s what one person asked about running Tungsten bulbs at a different frequency:
