I run into this issue with alot of the buyers. They think it's a regular replacement bulb that is painted blue or whatever color you like. But, that is NOT correct.

HID Technology:


XENON HID lamps do not have a filament. Instead the light is created by an electrical discharge between two electrodes in an air tight tiny quartz capsule filled with xenon gas, mercury and metal halide salts. This improves durability as road vibrations can cause damage to coil lighting technologies. These light sources also produce a blue-white light that is safer because it is closer to natural daylight. The color temperature is approximately 4200 K compared to 3200 K for halogen. The increased light output from a 35 watt XENON HID lamp is approximately 80% more light then a 55 watt halogen bulb. The XENON HID system will also draw less power from your vehicles electrical system.

How Do I know what kind of kit to order?
With so many makes, models and trim levels of vehicles it is important that you check and make sure what type of bulb your particular vehicle needs. You can find the type of bulbs your specific vehicle uses in several locations. One place is the head light lens, the bulb type will be molded into it. Another place is on the bulb itself, the bulb type and wattage will be printed or molded into the base. The vehicle owner's manual may also tell you what type of bulb you need for your head lights and/or fog lights. If you still cannot find the bulb type you require we suggest you contact your local car dealership and inquire as to what kind of bulbs your vehicle uses. Once you obtain the correct bulb information you may order the corresponding HID conversion kit.

Will I have to modify my headlights?
These HID conversion kits are designed to be plug+play. Our custom molded bases will ensure you will not have to modify your vehicle headlight assembly in any way. Furthermore, the wiring harness that is provided with our product will plug directly into your OEM headlight harness with no wire splicing, tapping, or cutting.

Headlight Bulb Cross Reference:
H4 bulb can be referenced to as a 9003 or an HB2.
9004 bulb can be referenced to as an HB1.
9005 bulb can be referenced to as an HB3.
9006 bulb can be referenced to as an HB4.
9007 bulb can be referenced to as an HB5.

It is VERY important to tell 1320 Engineering the YEAR MAKE and SPECIFIC MODEL when ordering a kit. There are SOOO many varieties between models and years. For example, a 2006 Yukon and a 2007 Yukon may LOOK the same BUT the bulbs are TOTALLY different.

I have installed over 100+ kits and I have had to fab alot of setups because of the rarity. Plus, fog light setups in alot of the newer cars require custom installs. Please inquire about this.
