So i've removed the bulb from the little mount thing without any hassle, but when i've gone to test which way i should put the LED, I find that it will only light up for a few seconds before i goes dim and eventually dies...i've killed two LED's this way just to make sure that the first one wasn't faulty, and my best guess as to the solution is that i need to put a resistor in there with the LED. Anybody done this before?

yes you do need a resistor. put two or three leds in so that it shines evenly all around. i did with mine, a friend help me out.

It takes something smaller than a 74 I believe, mine seemed much smaller than a 74 at least. The bulb also was not removable from it's base, it had a plastic twist-lock base, I believe.

putting an led there is a fire hazzard. i took mine of, plastic melts, and burns pretty quick

Why fire hazard? A tiny led cant be that dangerous? And if it gets too much voltage, it just dont work anymore.

if you smoke and if you use lighter, the heat from the lighter can cause the led to heat and melt.
not exactly something ill risk my celi for. Now if you are going to use it for chargers, no biggie. just throw the lighter away....  This theory has not been proven, and surely nobody wants too.

have you tried to put a plastic tab next to the red hot lighter. It kind of melts. The LED is not made to stand those temps.
