I'm sure it would depend on what lights you have fitted. surely would be a bit crap making angel eye lights that you can't change the bulbs on.
 
I wish it was easy to change because i need much brighter bulbs but i'll be damned if i'm going to take my bumper off again.
 
Just got my angel eyes through and each of the rings take 4 capless bulbs, you can see the black/white wire in each "corner"

if those capless bulbs are 501 style then i would use ( N 01775310 ) Ibiza 3 Cupra R sidelights - purest clear white i have seen this side of an led
 
Yes they are ta for the number.
Got a few different leds here and just powered them up and they look rank!!!
I shall get some of them then :)
