At first it works while you back up. But there are issues:
1. If the Sun is shining behind your car's back, the back-up light will reflect the light into the alarm and it will beep forever.
2. It runs on battery so it runs out of juice quickly.
I would go with a special light bulb which has an alarm built-in. Amazon has one but I don't know if it fits my car or not. |

| Back Up Warning Alarm |
Wanted a back-up audible alarm for my Jaguar XKR - this device is self-powered, needs NO wiring, and is innocuous (wife thought it was a 'tracer'!). Used light energy to power an audio oscillator and amplifier, top generate a "Beep!" Beep!" "Beep!" sound as long as the backup light is on. Mount with double-face tape over the revwerse lamp lend, on the outside - not app[arentluy affected by car wash, curved mountuing surface, or (so far) bright sunlight. A cheap and easy solution to my defined problem. |
