The Short Story
I'm going to go with the Summit Technologies HAWK Array rather than rolling my own. It's less expensive and would look better than what I would build for my own usage.
NOTE: This is a lie, I wound up rolling my own anyway.
The Less Short Story
For the purpose of testing my car's electrics I built a prototype indicator array. It half worked. I sunk all of the LED cathodes to a common chassis ground because I made bad assumptions.
What indicators sink to what, briefly.
- Discrete Source, Common Sink
- Right Turn
- Left Turn
- High Beam
- Common Source, Discrete Sink
