What is the stock replacement reverse (backup) light bulb for a 2003 Ford Focus SE Wagon?

Asked by Aug 03, 2012 at 10:56 AM about the 2003 Ford Focus SE Wagon

Question type: Maintenance & Repair

A Ford dealer apparently replaced the originals with the same bulbs used for the turn signal/flasher/brake lights.  They went out after a few hours of usage. I have gotten three different replacement bulbs from auto parts stores.  None worked.  I suspect the circuit has been damaged by the dealer using the incorrect bulbs.  Can someone with actual knowledge of the specified, OEM part number for the replacement bulbs please provide me with a manufacturer name and part number?  Thanks.

For the wagon, you must use any Bulb #921 or 921LL, the LL satnds for Longer Life. I suspect your mechanic install the bulb #3157 which is for the tail lamps and reverse bulbs for the sedans ONLY.
