First, a pop-quiz.
Please tell me what is wrong with this picture:
Anything missing? Anything out of order?
For one, I'd say the limiting resistor.
It's hard to tell from the picture, but the leads may be reversed. Did anyone check to see if it worked before soldering it together? Also did anyone check to see if the diode was rated for 9 volts?
When it comes to this kind of material, I'll admit I'm poorly educated. What you see is a "trail run" of miniature lighting I plan on installing into a prop. When I was working on it, the diode did blip some light at first. But that is as far as I have gotten. I know it's not the battery nor bad wires (I've tried several of them). Perhaps I purchased a bad diode? I don't have instructions for this kind of thing, but pictures of something very similar; so I follow those.
What I want to create is a set of about 5 to 8 LED lights (10mm) running off of a battery source.

heres a few links that may help ya some.
John is right,
the limiting resistor is missing.
And you need to make sure the red lead is attached to the pin that is connected to the flag in the led (HOT).
You can also use one battery to run 2 leds off of with no problem.
If it blipped and then quit working you probably blew the LED. LED's hooked up in that manner are basically just a short a across your power source.
Yeah, the 'blip' is a dead- (ha ha, sorry for the pun) giveaway. You *murdered* a LED. Go get a resistor, and a new LED and try again. Killer.
Hopefully it didn't have any family.Yeah, the 'blip' is a dead- (ha ha, sorry for the pun) giveaway. You *murdered* a LED. Killer.
Pin? Flag? Whosajigawha?And you need to make sure the red lead is attached to the pin that is connected to the flag in the led (HOT).
