Luggage Locator — Perhaps not the best solution to the problem

From the website:

Luggage Locator

Locate your luggage in an instant.

Luggage Locator makes it easy to find your bag on the airport luggage carousel, in hotel lobbies or train stations.

Just attach the receiver to your suitcase and keep the remote in your pocket or on your keychain.

One press of the button sounds the alarm and lights up the locator.

Works from up to 60 feet away.

Includes two lithium batteries.

I can't speak for you but it seems to me that if an alarm goes off and a light starts flashing on some bag on the luggage carousel it's quite likely, in this day and age, to trigger an evacuation and a call to the bomb squad.

Try buying a red suitcase instead — works for me.

A Luggage Locator — while they're still available, which I predict won't be for long — costs $19.85.
