Frequently Asked Questions

What is an HID conversion kit?

An HID (High Intensity Discharge) conversion kit replaces your vehicle’s factory halogen bulbs with HID bulbs and ballasts. Unlike halogens that use a filament, HID bulbs generate light by igniting noble gases within a sealed capsule, producing a much brighter and whiter light, often with a longer lifespan and greater energy efficiency.

Are HID conversion kits legal?

The legality of HID conversion kits varies by region and specific application. In many areas, installing HID bulbs into a halogen housing (reflector or projector) that was not designed for HID can be illegal, as it may create excessive glare for oncoming traffic due to an improper beam pattern. For legal compliance and optimal safety, HIDs are best used in projector headlights specifically designed for them. Always check your local regulations.

How do I choose the right bulb size for my car?

To choose the correct HID bulb size, you need to know the bulb type currently installed in your vehicle’s headlights. This information can typically be found in your car’s owner’s manual, on the existing bulb itself, or by using an online bulb lookup tool provided by automotive parts retailers. Common sizes include H1, H3, H7, H11, 9005, and 9006, among others. Ensure the HID kit you select matches your vehicle’s specific bulb type.

What's the difference between AC and DC ballasts?

The primary difference lies in how they power the HID bulb. DC (Direct Current) ballasts are generally less expensive but tend to cause bulb flickering and have a shorter lifespan. AC (Alternating Current) ballasts provide a more stable power supply to the bulb, resulting in more consistent light output, less flickering, truer color, and a longer overall bulb and ballast lifespan. Our research indicates AC ballasts are almost always the superior choice for reliability and performance.

Do I need a CANBUS decoder with my HID kit?

Many modern vehicles use a CANBUS (Controller Area Network Bus) system to monitor electrical components, including headlights. When you install an HID kit, the lower power draw compared to halogen bulbs can trick the CANBUS system into thinking a bulb is out, triggering dashboard error messages or flickering. A CANBUS decoder (also known as a warning canceller or resistor) communicates with the vehicle’s computer, preventing these errors. Based on owner feedback and vehicle specifications, most newer European and some American vehicles will require a CANBUS decoder for error-free operation.
