Can someone tell me why an incandescent bulb will not work in a socket but an LED will? I find this odd. I have a DE Simpsons and in one of the backbox sockets was an incandescent 455 bulb that will not come on at all. The bulb is good and works in other sockets. I tried a 44 incandescent but it will not come on either. I tried a 44 LED and it works. I believe this bulb is supposed to be a 455 and blink so I am confused. I assume a 455 LED (don't have one yet) will work but I'm just curious why an incandescent will not. Any help is appreciated.

Right on. I know the difference in all of the bulbs, I just didn't know why only an LED would work.

Ok thanks, I will look into that.
