## What is Grote Tri?

The Grote Tri-Color warning light has a large number of features built into it. You can now program these features using your iOS device with the Grote Tri-Color Programmer!


The system works using the flash on your phone to send data to a sensor on the warning light. Simply set up your light as described in the manual, select your options, hold your phone flash near the sensor, and program your light in seconds!


You can program:

1. Patterns for each of the 3 enable wires.
2. Which colors are enabled by each enable wire.
3. Phase
4. Functionality such as steady burn, cruise, and auto-dim.


And then preview your pattern in the app!
