HCC §24-34
When your vehicle must have lights on
Read the official text at hawaiicounty.gov ↗This rule says when you must turn on your vehicle's lights while driving on county roads. You need lights from half an hour after sunset to half an hour before sunrise, and also when it's dark or foggy enough that you can't see people or cars 500 feet ahead. There are exceptions for parked vehicles.
