What bulbs size does the 2006 Nissan Altima use for illuminating the speedometer?

[ZjohnMsmalls]

I have a 2006 Nissan Altima and im trying to replace the speedometer lights with blue LED ones. I took apart the instrumental cluster and only found 1 bulb to replace that makes the speedometer glow. Is that right? does it only take 1 light to illuminate it? And what size is the bulb? is it the 194? but i dont know what type and width and length the bulb is. ALSO i want to replace the Gear Shift lights where it glows P R N D 2 1. How do i get to that on the 06 altima? i heard you just pry it off, is that right? and does anyone know the bulb size for this also? Thank you for you help in advance!!
