Headlight Compatible With Lexus GS300 GS350 GS430 GS460 2007-2011 CAPA Certified Left Driver Side HID

Your headlights will be warm to the touch from the heat generated by the bulb. The filament inside of a headlight bulb can reach temperatures of over 4000º F while the temperature of the glass surface of the bulb can exceed 150º F. This means that heat will naturally radiate to the exterior surface of your headlights. This intense heat is also what will help your headlights remain condensation and moisture free. However, to prevent burns or other injuries, be sure to let bulbs and headlight assemblies cool completely after use before handling.

HID stands for "High Intensity Discharge". These bulbs use an electric arc rather than the glowing filament in a Halogen bulb. HID headlamp bulbs do not run on low-voltage DC current like a Halogen Bulb, so they require a ballast, which controls and regulates the flow of current. This ballast will require an ignitor to light the bulb. This is either integrated directly into the bulb or as a separate unit which is occasionally part of the ballast, similar to fluorescent bulbs in your home. In a vehicle, HID bulbs tend to be much more expensive to replace than a Halogen bulb.

These types of lights used to be more popular on most European vehicles, but are becoming common on other makes and models. Projector lights are lights that have a filament located at one focus of a reflector, and a round glass or heavy duty plastic condenser lens at the front of the lamp. These lenses in front of the light bulb distribute the light evenly across the front of the vehicle, and can give a larger range of visibility for the driver. The bulbs themselves are usually common Halogen bulbs that can easily be changed.
