dash lights

I am trying to replace the lights on the backside of my dashboard. I want them to be hyper white. I have a 99 cavalier ls and i was wondering if anyone knew what size lights i will need.

They should be 12v...thats what my cav is. It should say right on the bulb if u take the bulb out. My Cav is a 98 so it should be the same.

look in your owners maunual it should tell you every bulb size that your diffrent parts take.
