i had wire cages over the light fittings, and basically the welding on one side of the cover was coming loose. so i was trying to fix that as the snake was using it to climb around the cage, when my hand caught the cover and smacked into the bulb. the light fitting that is more screwed was the main one, the power went into that fitting and then into the next one.
by knocking the light bulb with the cover it shorted the two wires together blowing the above light fittings to crap.
warning to all those ppl out there, never use plastic even if you plan to use a light wattage globe. spoke to a sparky about it and he said its a lucky thing i did what i did as it could of lead to fire down the track..............
