Headlight Right Passenger Fits 2001-2002 Subaru Forester

Xenon is an inert gas that allows a bulb to produce a brighter light with a longer life than a standard halogen bulb.

Your old lights probably had moisture or condensation in them too, but the older, dulled and oxidized lens makes moisture less noticeable. Now that you have those new clear lights on your nice car, all of sudden you’re really looking at them, which is completely normal. Without going into too much detail, It's a fact that condensation happens just about anywhere. If there's a temperature difference between the inside and outside of the lens, moisture will occasionally develop, and, since your Halogen headlight bulbs put out some heat, the inside of the headlight is full of warm air while the outside is cooler. This is sort of like how the front window on your car can fog up and you have to turn on the defroster vent to clear it all away: The condensation in your headlights will usually dissipate after the headlights are turned on, as the heat of the lights evaporates the moisture. Your high beams will usually produce more heat to clear any condensation more quickly.

You shouldn’t touch the glass portion of a halogen bulb, as any debris, even oil from your skin, can shorten the life of the bulb. Wearing gloves while handling bulbs or working on your vehicle will protect your hands and sensitive components from dirt and grime.
