Q.   What wiring is required?
A.   None at all. The transmitter unit plugs into your towbar socket and is self powered. The receiver unit is powered by a PP3 battery and has no connections. The two units communicate by 433MHz wireless transmission so no wiring is necessary.
Q.   How do I check my lights are functioning correctly?
A.   Once the transmitter unit is correctly connected between the towbar socket and trailer plug. Switch on the receiver unit and the display will replicate all light as they are illuminated on your trailer. If a fault is detected the appropriate light will flash as will the fault light, and an audible warning buzzer will sound.

Q.   My caravan/trailer has an unusual light configuration, how does Lightguard know if my lights are working correctly or not?
A.   Most caravans/trailers are a fairly standard configuration. However, if you have a number of side repeater lights you may wish to use lightguard’s ‘teach’ facility to let lightguard ‘learn’ your trailers lighting configuration. Once done lightguard will be able to identify any lighting faults on your trailer.
Q.   My trailer has no Fog lamp. Will lightguard always show a fault?
A.   No. Use Lightguard’s ‘teach’ mode to let it learn that you do not have a fog lamp fitted. Thereafter no fog lamp faults will be displayed.
Q.   What happens when another vehicle fitted with Lightguard passes me on the motorway? Will signals from the other Lightguard interfere with my Lightguard?


  No. Each lightguard has a unique identification code that ensures that there is no interference between units.
