LED & HID Lighting
"Xenon HID headlights, or high-intensity discharge, are a common alternative to halogen bulbs. Instead of halogen, HID headlights use another gas - generally xenon. Passing xenon over an electrical charge allows these bulbs to burn much more brightly than the glowing filament design bulbs, which leads to efficiency savings and improvements in aesthetic and visibility.
These headlights are usually brighter than LEDs and halogens, but they are significantly more fragile, and they are not solid state in the same way as LEDs. This means that HIDs will need replaced much more frequently than LEDs, and in some cases can even burn out before a standard halogen headlight would.
HID headlights are a significant improvement on halogens, and depending on the color temperature, you can choose a light quality that suits your preferences. However, over time, these bulbs can start to burn at lower or higher temperatures, changing the quality of the light they emit, before burning out. HIDs will do a job
LED lights produce similar improvements to HID headlights, but they go a step further in providing both clear, bright lighting and durability. By 2030, industry estimates project that as much as three quarters, or 75% of all lighting sold will be LED based, and car headlights are no different.
Now that the component costs of LEDs are coming down year on year, more people are choosing to upgrade their headlights to LEDs, and they are not turning back. LED lights use a number of light-emitting diodes to convert electricity from your car into light, with significantly greater efficiency than both HID and halogen bulbs.
Because they are solid state and built to last, these headlights can in theory be used for decades before they will need to be replaced, saving you the ongoing maintenance burden and costs associated with other bulbs.
Furthermore, LED kits can be easily installed on your car, either by yourself or by a professional mechanic in just a few minutes. Once you’ve installed your LED headlights kit, you can expect high quality, warm, white light, illuminating significant portions of the road ahead when compared to basic halogen bulbs.
, but they are problematic over time, and in many respects LEDs represent a more sensible choice for both short and long-term use"
