Opps..
I have wanted to share this with you and forgotten about it. What happened? The other day I have my toilet's light bulb change to a higher light voltage.
I smell something burning for like a few nights and I didn't know what was it. Until one night something fell down inside the toilet. I was so scare and I took a peep, wow I can't believe what I see. The cover of the light bulb melted! It has a big hole in it, it just fall off through the light bulb. This means that the light bulb voltage is really high and luckily the house didn't burn up.
It's really dangerous and I am more careful now. I didn't change the ligh bulb after that, its only difference is that there's no cover on top of the light bulb. That's okay with me.
