Hi guys,
Looking at switching my yellow looking bulbs to white LEDs. I've bought the resistors to manage the errors but now can't work out what bulbs I need.

The car has the DRL switch which seems to throw a dimmer light to the side lights. Does that mean there are two bulbs or just one?
What fitments are they? I don't have the headlight adjuster switch so guessing not xenon's.

Thanks
