Well iv replaced the two lights in my car, i think they are the low beam lights imnot sure, they are the ones which are closest to the blinker. The ones which are on when your headlights are on but highbeams are off. Anyway i put some Xenon H4 size bulbs in and it works a treat, but now there is a bad colour mismatch such that the highbeams are still the ugly yellow colour. What size lights do i need to replace the highbeam lights in this car?

Remove one of the globes and take it to the same place where you got the new headlight globes...

Ask them to match them for you...

55/100 are standard, You have burnt the inside of the (PLASTIC) lense of the headlight by using higher watts globes
