You dont need cambus bulbs i just got cheap smd ones off eday work fine
You're a lucky one dude, but almost every one here, myself included, needed can-bus ones because others give errors on the dashboard and just die out because the load is different from the one the car gives, which is the problem I am facing with my LED strips right now, except they don't give errors on the dashboard but flicker and then stop working at all.
Also facelift Leons, for some reason, detect non-canbus bulbs much quicker than pre-facelift ones.
Got the info from here that i didnt need cambus friendly bulbs. had them in a good eight months no problem lucky me i guess
