This circuit looks the current not enough to light up a atandard LED..

咁即係冇辦法?
諗住整左都會長用, 長用就即係長插住,
冇人響屋企時燒左, 咁樣就算"啪"到幾大聲到冇人知law?
如果有十個八個咪去完街返來要"猛"十次八次來check下?

睇完真係好想快d整添 :p
我想問下可唔可以加粒LED響個circuit中間,
可以知道下個filter係唔係正常都好, 唔使下下拆fuse睇.

請看看reply #178
我之前有說過

有那些插頭是內置LED?
不是220v bulb的嗎?

有，不過較貴
$14左右

哦, 其實加左LED會唔會影響個filter效能?

應該不會啦
就算有都係微乎其微

p.s.有錢都一早買左filter拖板啦

I have heard from Pro Audio users that any filter with a Neon lamp in it is a bad design, as it will add noise into the circuit itself....

You can see the trend in expensive mains filter.... they rarely have anything like neon or LEDs to show their status....

Not sure about the physics of it, but I do trust their words :P
