How to do music video light rays/strobes

Does anybody know how to do the typical Ray Kay style kind of strobe lightings?

Booba – Caramel – YouTube

This isn’t a ray kay video but it has his similar technique with the blue streaks.

Does anybody know how to do that in premiere/after effects? Thanks!!!
