The 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 car drivers prefer a yellow beam because it provides a better color contrast in rainy, foggy and white out situations. The 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.

Technology 

• Xenon Gas added to the halogen gas mix helps cool the Filliment and allows for a smaller wire diameter with more coils that glows brighter and makes about 80% more light than a standard Halogen Bulb.

• To decrease the temperature of the light, an envelope made of yellow quartz is used to filter out the blue light which in turn yellows the light to about 2600°K. 

• Any filtering will, of course, block some of the light. Comparison with simular bulbs without a colored globe shows a loss of lumens on the 5% range.

• Sold for off road and competition use.
