If you don't drive with your lights on, why not?
People in Australia don't seem to use their headlights during the day. In fact some people don't use them when it is rainy, misty, dusk, dawn or other times of low visibility. If you drive a white car in the mist without your fog lights on you are almost invisible. If you drive a grey or black car in low light you are almost invisible. If the person driving in the opposite direction has the sun in their eyes you are far more visible with your lights on.
Lights on increases your visibility and hence your safety no matter what the conditions so why don't people put them on?

My father taught me to always turn the lights on when I got into the car and then lock the door (an older car with non-auto lights). When you go to get out you can't cause the door is locked and then you remember all the time. Has always worked for me
