facelift e53 turn light signal bulb replacement passenger side

[omodos]

hello, so I dug out the manual from the glove box and absolutely no mention of how this is done, so I popped off the cover off the back and all i could see was the xenons....

Did some reading here and there, but can anyone confirm that the whole headlight unit needs to come forward out and over the bumper to get to the turn signal bulb? and how much slack is there once the screws are off and you can pull the headlamp forward? we talking an inch? or more?

better still and diys with pic regarding the screws that need to be removed?....i guess at 9.5 odd years old i cant complain at having to change a bulb but jeez it sould be an on the go type job.....and for the those that have done it on a facelift (mines a nov 2004 build) does it class as an easy diy? thanks in advance
