Has anyone succesfully replaced the rear interior lights (the ones in the air vent outlets) with LED's? I understood they are W5W bulbs, and although I have (eventually) removed the lens cover I cannot get the bulbs out. They are surrounded by a metal shield which makes it impossible to grip the bulb, and only one side of the shield seems to detach - again not providing sufficient space to pull the bulb. I dont want to apply too much force for fear of breaking something. What am I doing wrong? 😬
