I replaced those bulbs a few weeks ago. The dome light is #3022 or 3175. Be Careful!! I was told by the dealer that it's 3175, but it wasn't! 3175 is too big and won't fit. I ended up using 3022. Pop off the cover and take a look before you buy. If the lens is .5 inches then it's 3022, if it's .75 inches then it's a 3175.
As for the map lights, I got bulb number 194, which I'm told is the same as 168?? In any event, both are 5 Watts.
They shouldn't cost more than about $15 total for all of them. I paid about $15, shipped.
