hi there
Remove screw at the bottom of rear lens ,push slightly up so you can get you fingers under lens and pull it out ( be careful lens has clips on it)
the you can see which bulb you need to take out.
just turn holder and it should just come out showing you the bulb to replace.
if screw gets stuck use wd40 then try unscrewing or if you can get it unscrewing part of the way up , see if you can get a flat screwdriver just under screw head and prise screw up while unscrewing with other screwdriver. has work for me before. hope this helps
