Re: Headlight output degradadation over time? the number of hours in operation is a guideline. additionally the number of hours listed for the life of the lamp is not until filament failure it's until it dims to 50% of rated output.
otherwise the poster above about evaporating tungsten and halogen gases metal halides etc is correct that is the basic process.

said by Sylvania :
Q) How long do the headlights last?
A) The life of any halogen bulb varies based on vehicle type, vehicle voltage, amount of time the bulb is on, road conditions, proper installation, and correct application. The average life of SilverStar® headlights is approximately one year. With our SYLVANIA SilverStar® products, the primary goal is to offer the brightest, whitest light. Research has shown SilverStar® headlights improve driver visibility and reaction time. However, since our SilverStar® headlights are up to 35% brighter and our SilverStar® ULTRA headlights are up to 50% brighter than standard halogen, they may have a shorter life span compared to our other products. We offer a wide variety of products to satisfy customer needs including brightness, durability, color options and increased visibility. We recommend evaluating your headlights annually as part of your regular vehicle maintenance.

There are three types of Silverstar bulbs. The brighter the bulb, the shorter the life. Some only last about a year.

Those SYLVANIA SilverStar bulbs say they are street legal so they should not be too bright to blind other drivers.
If you got the super bright illegal HIDs for your headlights you will be like one of those a-holes that blind on coming traffic with your regular headlights.
Do you really notice a difference in the whiter light than OEM with the SilverStars?
Last week I used a $10 kit to clean the oxidation off my plastic headlights. 1st time in 150K miles so yeah they were really foggy.
The difference at night was amazing like 3 times the brightness.
Since I have been in the south I have done "state inspections" for louisiana and Texas. Not once have they said anything about the oxidized fogged up headlights.
I have no idea what their state safety inspections are for when they dont actually check anything.
