Dash light is dim when I turn my headlights on. Battery and alternator is ok.
on 2000 Acura RL

Any suggestions?

Dash lights are supposed to dim when you turn your lights on, because at night, normal illumination of the dash would be way too bright. There is an adjustment knob, look in your owners manual, it is usually on the left hand side of the dash.
