If you want them lit up JDM style, you'll need 4 red bulbs (2x380 and 2x382 I believe) and then two indicator bulbs (not sure what code they are) I highly recommend buying SMD LED units like mine! Check the build thread for links
Looked em up on a tyre review site the other day because we need some new rubber on the Leon, seem a bit poo tbh :/ Might go for Uniroyal Rainsport 2 which are supposed to be amazing
