Style and Appearance

Legal and Safety Considerations

I make sure the headlights I choose are street legal and DOT or SAE compliant when possible. I do not want to install anything that could cause problems during inspection or make nighttime driving unsafe. Staying within legal standards gives me peace of mind.
