Headlights.. Osram night breakers etc, drl, I'd leave as is.. Do not buy the led h4 eBay bulbs.. These are illegal, as they are not CE approved and as a result you can blind or dazzle oncoming traffic.. You could look at h4 to h7 unit swap as the h7 headlights are plug and play.. If interested in that route msg Pauly or look in the forum shop.. They will also have a different drl setup..
