A nice easy one
Josh your thinking about the indicator replacement hatch in the arch
no need to take the lamp apart open the bonnet
Look through the lens and make a mental note of how the bulbs aligned (look at the bulbs in built reflector)
at the back of the lamp there is a rubber disc pull that off
now feel in the hole for the back of the lamp there is a black electrical plug pull that off the bulb.
now feel for the wire retainer you have to push it in and to the right or left then release and it drops down.
pull the bulb out
put your new bulb in (dont touch any of the glass with your fingers (if you have done already you MUST clean them with IPA or meths before you fit them or they will burn out prematurely)
slide the new bulb in and align it visually from the outside and give it a wiggle till its tags drop into the recesses on the inside
lift the sprung metal clip back up and push tight and move to the left/ right and release. it will lock in place if not try again.
next refit the plug on the back of the bulb
then put the rubber cap back on.....
and now test the lights.
