I turn on the headlights and the dash; speedo & engine gauge panel dosen't light up. I don't know if its one or several bulbs. I don't know where the bulb(s) are. i.e do you need to take out the whole gauge panel or is the bulb somewhere you can get to and replace. I don't know how much more to explain this. When you look at the speedo at night you can't see it. I don't notice if this effected the radio illumination everything works except the light.
