Lamp replacement - vanity mirror lighting
The vanity mirror's lamps are fitted inside the lamp lenses.
Insert a screwdriver under the lamp lens and gently prize up the lug on the edge.
Carefully detach and lift aside the lamp lens.
Using needle-nose pliers, pull the bulb straight out to the side. Do not squeeze the bulb too hard with the pliers. Otherwise, the bulb glass could then break.
Replace the bulb and put back the parts in reverse order.
