Selv circuit - short circuit - bulbs blown

[Ziggie]

Garden lighting 12V AC from transformer wired with 2 wire and extension cables ran 2 LED lights in parallel. Unfortunately water and mud managed to cause a short circuit. The two lamp bulbs blown were further away from the transformer than the fault.

Q1. Is this expected?

Q2. Is there an easy way of protecting the bulbs if it were to happen again?

No, the two problems may be unrelated. A short might damage the transformer but should not affect the lamps. Also, arlt 12V, to count as a short it really has to be metal touching metal pr a very serious case of metal tracking. 12V AC wiring can work underwater remarkably well.

Are the LED bulbs rated for 12 V AC?

Yes rated at 12v

The transformer was fine as was the 230v feeder ( didn’t blow a 2A). Also when I separated the wires at the fault, and replaced the bulbs all is ok.
