    I wired some yellow LED's in my threepio eyes a long time ago, but they weren't that impressive. I wired three LED's in a series with a resistor to a 9v battery for each eye. I did it more or less correctly, but they weren't very bright even though they were "ultra bright" LED's.

    I'm curious if anyone can offer any advice to a better light source and how it would be wired up. There's definitely something better out there than what I used.

    i cast 3, 3mm yellow leds into clear resin then painted the back of it silver to stop the light from escaping from the back.

    worked really well.

    I do know that the real lights were normal bulbs but im really pleased with how mine came out.

    hope that helps

    With my very limited electrical knowledge, I'd suggest you might be using the wrong resistor?

    There was a very helpful circuit diagram floating somewhere for 3PO eyes - I'm sure someone has it?

    I did the same thing of adding 3 yellow LEDs till tk409 suggested I used "Garden Wedding Lights" - these are bulbs that are as big as LEDs, but just a tad longer.

    8 lights come in the package powered by 2 AA Batteries. I just cut off the 2 lights (you need 6) & replaced the 2AA battery adaptor with a 9V adaptor.
    They're very bright & better than LEDs, I think.

    did you have the leds sideways or pointing out the way, there is a big difference in how much light is seen, very limited from the side.
    i embedded some orange/yellow leds in a pair of lenses (pointing out)and they were very bright, almost too bright.

    I just redid the eyes on my 3p0 suit. Man, I think they may be TOO bright. :lol

    I used special LEDs that are ultrabright and also diffuse much better. They run off a 9V. I might have to scale down the brightness, although in person I think the eye lights look awesome. I used the MonCal brass eyes (they are spectacular BTW) with the included lighted eye assembly.

    Here is a shot of the eyes up close WITH the camera flash. You can still see the eyes are plenty bright:



    I cant get a representative pic with the flash off. Without the camera flash 3p0 looks like he is possessed right out of Batman Begins. :lol
