When reaching in from below, removal of the triangular panel (two Philips bolts at the rear, held with two latches at the front) will increase access space.
Pull off the connector, pull off the rubber boot (first pull outer rim from headlight casing, then get it off the bulb-base), detach the wire latch holding bulb in reflector (see pics in forum), insert new bulb, hold it in place with the tip of your index finger between the 3 prongs while flipping the wire back into the latch (again refer to the pictures and keep in mind that only minimal force is required; if you give it full push the thing won't latch...), rubber back on (observe the TOP marking and the small tongue on the bottom), connector on, triangular panel back in place... done on less the 5 minutes...
Removal of windscreen, garnish, etc... does not help much on an ABS model, the control unit is blocking access from the top.
