That would be 26 weeks x 12 years = 312 x 2 bulbs = 624 bulbs (so far). Can you pinpoint when this annoying exploding lightbulb problem first popped up?

How does the person remove what is left of the bulbs once they explode?

Does this fixture sit anywhere near grass?

Do they ever use water sprinklers?

Is there any plumbing in the garage?

Where do they purchase their bulbs? Are they using the same brand each replacement? Did they buy them in bulk somewhere?
