Optilux Extreme Yellow (XY) Bulbs are able to provide the vehicle owner with both fit and function. The Optilux XY Bulbs are designed to give you better visibility in extreme weather conditions as well as provide you with the look of the GTS Series race car lights. Race drivers prefer a yellow beam because it provides a better color contrast in rainy, foggy and white out situations. Optilux XY Bulbs produce a crisp yellow light from a bulb that is manufactured to the most precise measurements to provide the exact amount of light needed on the road.

The best way to figure out what bulb you need to replace is to pull out the old bulb and see what number it is. But here are a few common bulb types that we know of:

• 2002-03 Impreza/WRX low/high beam: 9007
