Foglights which bulbs??

Hi guys, I saw today on my way to work to see my right NSW beat up and then I looked in and there was the pear burst?!? How can something like that happen that a pear bursts. And that the stupid thing is leaking, is also quite great even though it’s a ZKW. Now I wanted to get a new pear on the way home. Which come in there. I know I could look at my manual but I don’t have that at work at hand. both pears change ? And how can I get the NSW closed again ?? Questions about questions ….. Greeting Bender
