Someone can help me With the iron man led eyes

In my circuit i am using one battery 12v, and a one reed switch, I would like To know the best type of led for the eyes.
Someone can help me with photos ?

I personally used EL Tape. They’re not the brightest light sources but provide equally distributed lighting and are easy to wire. There are a lot of other methods, just search through different forums and find what you want to do. I also used an EL panel fir the chest piece. Only minor downside to these things is the slight humming noise from the wire converters.
