So here is my first attempt at LED turn signals for the Camaro.
I opened up the stock turn signal, and removed the factory diffuser. I was hoping to use it, but because of the angle it's mounted. It was making the LEDs look wierd. So what I did was made my own diffuser using one made for a fluorescent light.

And here is how it looks when the turn signal is going.

And a night shot for comparison. LED on the left, and factory bulb on the right.

Here is a video of the LEDs 'blinking'

I still have some bugs to work out, I got a 'LED Ready' flasher for the car, but for some reason if I turn on my parking lights. The right turn signal indicator lights up inside the car. Not sure why it's doing that.
My goal is to get these working without having to use load resistors. Since those resistors defeat the whole purpose of using LEDs in the first place. Hoepfully I can get these to work perfectly.
