Right,decided to change the internal led back to another more modern hyperbrite red led instead..put an eye type device over the lens for night light from the red led being used inside which is spot on(a ambient light but cant be seen for miles),diverted the antenna from the transmitter to the ext.out-put socket..where an antenna then is plugged in instead for better remote reception(no need for that socket for sounder out-put now anyway)
Fitted new toggle switch too,where it cant be turned on in carriage..only off
Will get the other 3 alarms up to this state before adding at least another 3 extras...looking good
