Still waiting on one of the chemicals to clean the flux residue off. What a mess!! I did clean up (to a degree) what was left from soldering the LEDs and finished the strips today. Got the remaining components in place (resistors, diodes and connector) today which meant I could test them to see if everything worked as planned. Finished boards (front and back); the only components on the LED side are the LEDs......since the strips will be behind clear reflector strips, you probably won't even see the LEDs when unlit. White LEDs lit: Amber LEDs lit: This was just a quick test so the switchback circuit is not in place. The boards are just connected to a 12V power supply.
