Interior Light Bulb Question

This may seem like a silly question but no one I have asked has been able to tell me : What is the bulb number for the interior map light? I have a 97 Maxima with a sunroof so there is only one bulb to replace? Does everyone know which bulb im talking about? you have to push the button to turn it on. I tried using bulb # 1895 but it is very dim. Pleas help! this simple problem is driving me crazy Thanks!
