Ok ive searched but I just want to be 100% sure before I place the order for these. My old man has an 01 screw lariat w factory sunroof and from what I gather I need 3 4410s to do maps and dome. I dont live anywhere near him so I cant just go check the truck lol. Figure they would make a good albeit late fathers day gift. Hes still talking about his hids I got him for xmas

 

Anyone?

 

Look on superbrightled.com that's where I got all my lights from..

 

Sylvania has an guide that tells you the base size of all bulbs on vehicles.

 

The one's I put in mine are the 4410's from superbrightleds.com, the 2 fit perfect but the middle seemed too long. It works fine though. 4410-x9 is the number from superbrightleds site.
