• Kelvin Ratings: Color temperature is rated in Kelvins, showing the color of the light.
• Legal Colors: Acceptable colors are typically white or slightly yellow.
• Illegal Colors: Blue or other strongly colored lights may be illegal.

Focusing and Beam Pattern

The way light is focused is just as important as how bright it is. The beam pattern refers to how the light spreads onto the road. Poorly focused headlights can create glare. The beam pattern is meant to provide maximum visibility without causing issues for others. These requirements ensure that headlights illuminate the road effectively.

• Beam Angle: Regulations specify the angle at which the light should spread.
• Glare Control: Headlights must have designs that minimize glare.
• Compliance Testing: These aspects are usually tested to ensure they meet standards.

Choosing the Best Legal Headlight Bulb

Deciding what is the brightest legal headlight bulb can be tricky. You want to make sure your headlights are bright enough. You also need to stay on the right side of the law.
