To be honest I don't have any links any more and I wouldn't want you to buy the wrong ones.
There will be plenty of threads on this subject with up to date links.
You need
5w5 ones for sidelights (1 pair)
P21 ones for DRL's (1 pair)
38mm festoon ones for reg plate (1 pair)
Be careful, can bus friendly bulbs don't always work in the facelift leon, especially the reg plate. it is picky with it's LED bulbs so double check that they work before you buy. I have so called can bus ones in my reg plate but had to fit resistors. There are some out that do work without resistors in the reg plate now.
