I'm currently selling and fitting hid kits in ireland at the mo, ( new business venture ) the kits for £100 on flea bay are not worth a fuck! my kit uses proper ballasts ( hella ) and you can have a range of brightness's and colour! the brightest is about 8500k and the colour is a bright white, now if you like the bluish tint like and audi the brightness comes down a bit because of the blue tint to about 7000k! anyting under 6500k is not really any good in my opinion! kits available for all cars! typical car eg. escort cosworth fitting time 3 hrs!
