My inverters arrived today that are super tiny and will fit inside the buckle.
Quick post some pics

Like Taff, I did not use a resister when I wired all 12 in parallel (positive to positive, negative to negative).I've tested and re tested. The green lights are the dimmest lights and yellow and red are only slightly brighter. There is just too much voltage drop with these 12v LEDs. I don't know how Taff did it, but these don't work.

Here are the specs for the Red LEDs I bought -
LED 3mm Red Diffused 40mcd

They are pretty bright.
Link please?
Just an FYI, while it may work without using an appropriate resister, prolonged use will burn the LEDs out.
+1 on djjeremy's comment.
I'm no expert, but if you're using 2.x volt LEDs and not 12v LEDs, you must use a resistor of some sort. You say they are pretty bright at the moment... probably because more current is flowing through them than intended, and this will shorten their lifespan.
I have not tested them for long periods, so I guess time will tell. There are 12 LEDs connected in Parallel, so the 9V is distributed evenly across 12 LEDs which should be 0.75V each at full charge and less over time. This does not take into account any drops by the LEDs themselves.
You can flip the straps on the shoes.
I think there is more to it than just spreading the voltage over the LEDs. Can anyone elaborate on this?
