These were a great deal on eBay. I bought these long life halogen lamps for the steering responsive fog lights in my Subaru Legacy.
The fog light lenses are cracked and I plan on getting them replaced at the dealer in September. I'm going to ask them to install these long life lamps due to their yellowish light and the fact that I cannot access the fog lights on my own. I've heard warmer colored light is better for fog lights because it scatters less light. I'm sure I won't have to worry about these burning out for a long time.
