hi steve i take it you are using the feed that powered the standard bulb? how does shifting from main to dip is there much of a brightness lag happening? mine seem slow enough but the the dip on mine is on all the time the engine is running , imho the better way, requires a relay and a feed from the headlamp 'on' relay beside the battery

supprised how good the lights are now i have disconnected the aux spots as they worked with the main, i will put them on a separate switch
