Bhai its 110 volts if I am not wrong, i have seen people trying to pull out the light bulbs (although they have now put LED lights), chances of short circuit are next to impossible. You know if there is a short circuit the spark and smell should raise many questions.
My info says it was due to tableeghi brigade trying to make take within the compartment. Have you seen their travel cylinder they are bombs waiting to explode, I haven't seen anyone which doesn't leak gas.
We had one, on a picnic the damn thing caught fire due to poor quality of local cylinder/burner. If I were to hazard a guess it would be Tableeghi gas cylinder.
No comments there brother, 100% agreed. Thank goodness we were not born in an extremist india of today.
