Objects with curve modifier don't follow the curve?

I’m currently trying to make a christmas tree (since christmas is around the corner), but I’m having problems with the fairy lights. The light bulbs won’t follow the curve (cable of the fairy light), after adding a array modifier.

A small GIF, that explains my problem a bit better:

You’re adding the array after the curve modifier so the curve modifier can’t affect the array.

Doesn’t. It barely shows what you just said and is annoying as hell. This is how to do it properly
