I have a 98 honda civic dx & at night when im driving these lights won't turn on.

 

Checked fuses? Bulbs? On a 98 I wouldn't be surprised at all to find burnt out bulbs.

 

Each of those has a bulb behind it. If the rest of the lights work except for those it's almost certainly a burnt out bulb. For the gas gauge you need to take the whole cluster (speedometer, etc.) out of the car. It would be good to replace all the illumination bulbs in the cluster at the same time.
