iv had my rear lights dun with a auto coding box by kufatec a year ago yday i had taken my friends car to dis lad in Leeds and he had coded the back lights up to the brightest and i didn't actually believe him till i compered them both and thier are actully brighter. i had realised when you switch his on they flicker or 2 sec, wondering would they blow? is it worth getting mine recoded by him? thanks guys..
