This is one of the latest generation LED light bars from Sho Me who are one of the worlds largest emergency/utility vehicle lighting suppliers. 368 High Intensity LED's help you get noticed - and thats how many this unit contains. They are split into four "quarters" of 92 which operate in seven different flash patterns.  Double Alternating Flash - Quad Alternating Flash - Quint Alternating Flash - Mega Alternating Flash - Double Simultaneous Flash - Quad Simultaneous Flash - Random Flash You can generate the same flash patterns with your own LED's using a flasher module http://www.mobilecentre.co.uk/index.php?main_page=product_info&products_id=64 The base is constructed from extruded Aluminium, the dome is made from UV resistant Lexan (the same material is used in bullet proof glass!) A 3.6m lead (12 feet) is supplied terminated in a fused cigar plug containing an on/off switch and a mode switch to select any of the seven flash patterns listed above. The unit is 24 Volt DC only with a max current draw of 2.2 Amps (compared with 7 amps for a SINGLE halogen rotating beacon) With a height of 57 mm (82 mm inc magnets) combined with 165 kg (360lbs) of magnetic pull gives this lightbar very good high speed stability, minimal wind noise and little effect on fuel consumption. Overall dimensions are 440 x 230 x 82 mm.
