1. If the car is on, turn the headlights on. They should come on automatically in most vehicles.
2. If the headlights are already on, try turning the dimmer switch all the way up or down. That will sometimes adjust the brightness of the dash panel lights.
3. Check your vehicle's owner's manual for specific instructions on how to turn on the dash panel lights.
4. If none of the above works, there may be a problem with the dash panel lights themselves. Take your vehicle to a mechanic to have them repaired if necessary.
