2nd gen bulb sizes

[tamrat]

I am sorry, I know this has been asked here before but I need a bit more info. I am planning to get new headlights for my Surf, they are arriving from Dubai and I want to order the proper ones.

I want to replace both headlights, both parking lights, and the entire interior illumination (interior lights, instrument cluster, dash buttons and knobs etc...). What size bulbs should I look for?

Is there a difference between H4 and 9004?

Are these infos correct:
-> Headlights - 9004
-> Parking lights - 168
-> Instrument Cluster - 194
-> Interior lights - ???

Thanks,
