Install more outdoor lighting in your driveway lol

Start with the basic mate, you can pry the dome light assembly with a small and flat pry bar. Very easy removal, no screws! Remove the bulb and use abrasive paper to clean both metal ends. You may also want to do the same on the dome connection pins. Push back the pins gently with your finger so the squeeze the lamp properly.

Starting with above should rule out dirt and corrosion.

Could also be that the done light is not in its correct position (e.g. at off pos). I believe it needs pushing forward to be triggered by the doors. Center is OFF and pushed backward is ON. Something like that... forgot (read your user manual!)
