The chrome roof-like structure on top of round motorcycle headlights is commonly known as a "headlight visor" or "headlight peak." It is a decorative or functional accessory that can be found on various motorcycle models.
Headlight visors serve multiple purposes:
Style and Aesthetics: The visor is often added to enhance the overall appearance of the motorcycle. It can give the front end of the bike a more aggressive or retro look, depending on the design.
Sun Glare Reduction: The visor can help reduce the glare from the sun or other bright light sources. By shading the top portion of the headlight, it directs light away from the rider's eyes, improving visibility.
Weather Protection: In some cases, the visor may provide limited protection to the headlight lens from rain, debris, or insects. It can help deflect some elements away from the light source, reducing the need for frequent cleaning.
It's important to note that headlight visors are primarily cosmetic accessories and their effectiveness in reducing glare or providing weather protection may vary. They are often aftermarket additions and are not typically included as standard equipment on motorcycles. Different motorcycle models and manufacturers may have various designs and options available for headlight visors.
If you're interested in adding a headlight visor to your motorcycle, it's advisable to check with reputable motorcycle accessory suppliers or consult your motorcycle's manufacturer for compatible options and installation instructions.
