Their drawbacks are poor energy efficiency and a short lifespan. Prolean’s CNC Machining for Classic & Vintage Car Parts would be ideal if you deal in older cars and need headlights.
High-Intensity Discharge (HID) Car Headlights
These are also called Xenon headlights because they utilize xenon gas. These headlights don’t have a filament but generate an electricity arc in the bulb, which contains xenon.
HID car headlight
As the car lights’ name suggests, custom HID headlights are very bright and reliable, particularly at night. They have a characteristic bluish-white color, noticeable even without headlight symbols.
LED Car Headlights
LED (Light Emitting Diode) headlights are extremely popular for their durability, energy efficiency, and manufacturing versatility. These modern headlights are synonymous with the latest cars.
LED Headlight
They comprise several small diodes that produce a distinctive bright light. Despite style versatility, the quality of illumination is maintained. To add to the light quality, these headlight bulbs use much less energy compared to halogen car headlights lamps.
Adaptive Car Headlights
Adaptive headlights
These are the most advanced headlights. They can adjust direction and brightness depending on prevailing driving requirements such as traffic and road conditions. They offer advanced safety, for instance, by optimizing illumination at corners.
A popular version of adaptive headlights is Matrix LED, which significantly enhances driving safety. These headlights adjust their lighting depending on the driving conditions.
Note that there is the newest type of car headlights lamp namely laser light. Mostly found in high-end cars, laser lights offer better control and more illumination than conventional lights.
