Describe the bug
In Lesson 15 Modulo, both reset buttons do not work on the traffic light examples. Pressing reset after pressing advance() at least once will not reset the traffic light to its default state of [light_index = 0]

To Reproduce
Steps to reproduce the bug:

1. Click on [advance()] button at least once (not landing on red light)
2. Click on [reset]

Expected behavior
I expected the traffic Light will return to its default state; red light [light_index = 0]
