Coolant level sensor
A loss of coolant is often the first symptom of a mechanical failure, an alarm will sound when the coolant level drops below the minimum level sensors, allowing you to stop and repair before serious damage is done to the engine
Engine temperature sensor
A further fail safe, if the engine reaches an unsafe temperature an alarm will sound, giving you the opportunity to take action to prevent damage
Oil pressure sensor
Voltage level sensor
Alarm with mute option
The mute option is great when you are doing repairs and need to leave the ignition on
Start up component check sequence
The LBB will run through the sensors and check whether all levels are normal when you start the vehicle. This gives great peace of mind if you need to move quickly and have not had time to check the fluids etc.
This is one bit of gear which is a no brainer, essentially it is a false economy not to have one. I have one in my LR in SA which recently saved disaster alarming when the water header tank leaked. I did not have on in my LR in the UK, a bottom hose detatchent ended in warped heads - you dont notice an enfgine is overhgeating until you smell it - TOO LATE.
