@DMGer, A resistor is put in series with the light so that it can limit the current going to the light. You can use any resistor between 30ohms to 100ohms because resistance isn’t the key here, it’s just there to limit the current being supplied to the LED. If you don’t put in the resistor, there can be so many different implications, burning the LED is one of the them and since there is no limit on the current being supplied to the LED, it can damage rest of the circuit  as well.

I agree. I have burned at least 2 LEDs by forgetting the resistor. Now I have a notebook with all my shit I need to remember. 3-)

I burnt the LEDs down a bit but it works now so I'm happy! This is the best I could get of it because it's so dim.

Like everyone else has said, throw in the resistor. I found mine at my local Radioshack for $2 for a pack of 5. Also, try fresh batteries, the light tends to fade a bunch with the Power LED.

It needs a 47 ohm resistor (gbc).
62 ohms if your trying to do a dmg.

Put in a resistor.

Okay... One last question.
When I turn the front light on (I don't leave it on for more than 5 seconds due to fear of it burning out.) without a resistor it gets bright like an SP then it slowly fades away to where you can barely see it. Would the resistor fix this? I should also add that the first time I tried it it was normal like what I'd expect.

Hahah....47k.:P

You have to get a resistor separately. It was designed for the sp, not the gbc.

DAMN YOU MAX!!! jk
It was the resistor. For now it's connected without a resistor so I'll have to get one here soon. It turned out good!

Wait. So I just installed it and it didn't come on with a 47k...
I just heard though from a youtube video (I'm sure you know which one) NOT to use a 47k and to just go with a 47. Is this true or is my front light broken? Also while trouble shooting I switched the wires on the backlight just in case they weren't connected properly. Would this fry it? I'd really appreciate the help!

Yeah always use a resistor if something doesn't have one built in already. Essentially the resistor acts as a little shield for any minor peaks in voltage as it hits the resistor first leaving a smoother and more consistent power delivery to the installed item and more importantly its less likely to go over the installed items maximum operating voltage.

Interesting... But as a rule of thumb it's safer to use one.

Thanks guys!

I know a person who blew out their power switch fuse from not using a resistor.
