W5W / 501 Philips LongerLife Sidelights Box Of 10

LongerLife bulbs have been designed for preofessional drivers seeking for lamps that last longer in intensive use, and who want the best value for their money. With twice the life of standard bulbs, LongerLife means fewer bulb changes and best service life versus cost. They’re especially good if your vehicle has daytime running lights that stay on whenever you drive.

The innovative use of krypton gas limits tungsten evaporation from the filament. This is the key to the lamp's longer lifetime.
