Interior bulb types

[Jaq n dad]

Hi all. First post/question. I'm looking to change my interior lights and dash lights to the blue LED's. Can't seem to find any details on whT the bulb types are. Many comparison lists stop at 2010 model.
Mine is an SR 4x4 D April 2011 last of that shape before the current one. Probably an easy one for you guys.
Also what's the thoughts on changing to 6 or 8000 headlamp bulbs too when purchased new ute seemed ok but now seems to be dim in comparison to others I've seen. Cheers Steve
