2000 Accord 2DR Accessories, please help

I am looking to see if anyone can help me find the bulbs I need for my dome light. I am looking to change the original dome light to blue but I cant find a place to get the size I need. Any help will work.

Also I have been looking around for a cold air intake and have seen a variety of prices. I have been to procarparts.com and seen one for 45 and then one for 150. Does it matter or is this all a name issue again? On ebay there is also one that will total 35 after shipping.

I am new to this and any help you guys can give me would be great. Thanks:o
