LED assistance desired, Just a little project Options

[Bigmeanbulldog55]

I'm doing a little project for my Animal Training class and I'm having some problems with my LED set up. I've got some regular Radio Shack brand LEDs, model 276-1622. The power source is 4 AAA batteries putting out about 6.4 volts (volt meter measured). I'm only lighting one LED at a time with the 6.4 volts. I've done this twice now. The light flashes and then won't light again. Am I really blowing these things with little little voltage? I don't understand because I had some hooked up in my car running the 13-14 volts between the 2, and they worked just fine. They were a different brand though. What do I need to make this work?

As of now it's just 4. As part of my animal training training, I've worked with more rodents than anything. I'm trying to build a self contained animal training device. I start with simple behaviors in rodents and hopefully adopt the principle to larger animals. I'm using each LED on its own individual switch as cue lights to tell the rodents were to be or what to do in the presents of a certain color/position of a light. It’s not really as easy as it sounds, but it’s a work in progress.
