Traffic Courtesy Thank You Light

No need to give that awkward wave in the rear view mirror.  Thank the driver behind you with the push of a button.

What if you have no choice but to cut into another lane to make the exit ramp?  End the potential road rage from the person behind you with a quick flash of the smiley thank you.

Have fun in traffic now.

I printed this with ASA in hopes it will withstand the hot car temperatures in the summer.

For assembly:

The back cover can be glued or fastened to the front with M4x8x6mm heat embedment nuts and M4x6mm screws.

Soldering is required for the momentary switch.  All other connection can be made with automotive crimp connectors.

The switch box cover is glued to the housing with epoxy.

The switch box is mounted near the driver with double sided tape.

Wires running from the switch box to the smiley light are stuffed into door weather stripping.

The smiley “Thanks” light is mounted to the back glass with double sided tape.

I used purple LEDs as I believe emergency colors (red, blue) are illegal.
