This is a car reverse alarm, giving you a similar safety feature to professional vehicles like lorries.
As you backup, the car reverse alarm beeps alerting everyone behind that you are backing up and reversing out.
Now those lorry backing up alarms systems would be wired into the electrics and cost a lorry load.
Ours are cheap and easy to install.
Back up a bit!
Cheap and easy.
When you reverse your reverse light goes on.
These reverse car alarms stick onto your reverse lights, sense the light when it comes on and sound the alarm, stopping when the light turns off.
Very simple, but with a similar effect to an expensive system.
Nice and small these reverse car alarms work off a cell battery which is included and easily replaceable.
