well maxxyjazz,
I park on level`ish ground about 20 metres away from a facing the headlights wall.
if you have one good aimed headlight, use that as a marker,
then re align the out of setting one.
a quick check is stand in front of each headlight at a time then noticing how the beams look (focus) to each other with a bit of a gap in between each pattern of light.
do it on dipped bean though, then check the main beam.
oh, it dont work on a sunny day, so as its cold and bleak out, should be just fine mate.
good luck.
ps, are you sure you replaced the new bulb correctly - the 3 prongs in the correct offsett holes in headlight ??
