oh my god..
forget all the above guys and gals..
open bonnet, at the back of the headlamp unit you will find a wire type spring handle running along the top back edge of the main unit..( hidden just under the bodywork ) Pop this spring upwards..towards you..as you look into the engine bay, then the main rear cover will become loose and fall a little away from the unit,
there you can reach all the main bulbs and change them.. the spring clips that holds each bulb, insde the unit is a little awkward to tell you about here.. but it is a push and slide up.. to then remove the bulb.. then its a simple repeat backwards to fit it all back..
but if this is not easy to understand, and it isnot from me reading this over and over again lol. then do as they say above.. then you will be wishing you had read this more times over lol...
but the bottom line is.. no need for a main garage to do this.. its a 60 second job per unit.. MAX.
