The OSRAM ULTRA LIFE are the most durable halogen car bulb in existence,
we promise! They also come with a 3 year guarantee, the first of any
automotive bulb to do so.
If a bulb dies at night, your in a little bit of a pickle. A replacement
needs to be located and installed as soon as possible, because you
certainly don't want to put yourself in any danger. For drivers who are
often on the road at night, or for drivers who don't want to run the
risk of a bulb blowing at an inconvenient time the OSRAM ULTRA LIFE
bulbs are perfect!
These are the first automotive bulbs ever to have a 3 year warranty
