Design Testing

Here are some pictures of the prototype. The LEDs in the picture are much brighter than they appear. Slow flash was used in this picture which causes the LEDs to appear a lot dimmer then they really are.

PWM board with 2 4 LEDs in series.

The LEDs are cross connected in a grid fashion.

The test circuit inside the housing attached to the car. The finished version will be two 5 x 8 array of LEDs and a smaller array for the blinker. The LEDs in the picture are actually a deep red and not white yellow.

The final design will yield a brighter and larger area but even with only 8 LEDs the array is very bright. The LED data sheets suggest the use of 12-24 LEDs min of this type for taillight applications. We will be using 80.
