Backup Alarm Recommendation for a 2009 Ford Flex SEL

Question:

Do you have a backup alarm replacement bulb for a 2009 Ford Flex SEL. If you do, what happens if I replace both bulbs left and right?

From what I could find your 2009 Ford Flex uses a 921 reverse light bulb. We only have backup alert replacement bulbs for 1156 and 3156 bulbs so neither would fit your Flex. but we do have a solution that you can use.

You can use the Custer Surface Mount Back-up Alarm, # BK97DB. It mounts outside of the vehicle and receives power from the reverse light circuit on the vehicle. It will actually be louder than the bulb type alarms.
