The San Antoni lighthouse in Javea has not gone out in 150 years but it did this August .
It appears that there was a power surge which burned out some of the wiring .
For two hours the light was not so good and then it gave up all together . The systems for protecting against such surges were not functioning , hence the blackout .
As well as providing a warning light , it gives out a navigating beacon and so for that particular night boats were without this provision .
The system was up and running again within 24 hours and everything was back to normal the following night .
