Question 1

life span

Accepted Answer

FYI I emailed customer service after the light went out just over 365 days.Customer Service (OSRAM SYLVANIA) Nov 28, 15:13 COT Hi Amy,Our warranty is for one year from date of original purchase. With higher performance bulbs there is less life - SilverStar's typically last 9-12 months.Regards,Customer Service

Question 2

Can you use them for day time lights

Accepted Answer

If by "day time lights" you mean, e.g., can they be installed in the car's normal headlight position/fixture and used during the day, of course they can.  However, they are incandescent lights, and the longer they're on/used, the more quickly they'll run through their rated lifespan and need to be replaced.  If you mean, e.g., can they be installed in the car's normal "running light" position/fixture (only comes on in daylight hours, when the car is put in a moving gear), again, sure they CAN, if they'll fit/work in the particular car's running light position/fixture.  I'd probably avoid this, however, since these bulbs run pretty hot, and running light fixtures are usually smaller than headlight fixtures, with less ambient air flow around the bulb.

Question 3

Is this a high and low beam? I want to replace high and low on both sides

Accepted Answer

Fitment and application details for this bulb vary depending on the year, make, and model of vehicle it is being installed in. We suggest you may want to contact Sylvania directly at 1-800-729-3777 for assistance with your specific installation.

Question 4

What car models does this bulb fit?

Accepted Answer

You generally start out with the car, and then see what bulbs fit it, but the 9005 is a single filament bulb, normally used as a high-beam element.  It was said to be used by both GM and Dodge in some of their vehicles. Not sure what imports it all fits, but if your stock headlamp is a variety of the 9005 series, this bulb will fit.  Sadly though, the Silverstar bulbs have a short lifespan.  Good luck.
