dash lights... odometer/trip dull brown..possible for bulb change?

OK I know that i can't change just the blub and make my dash a new color...however..the dash lights on my 1992 where the miles and trip meters are light up really nasty brown, still lights up well, just ugly...... Is there a bulb that i can put in the place to make it say "hyper white" I don't care bout the rest of the dash just where the odometer is and the trip meter...

thanks
