TEST_FRONT_LIGHTS

A all-in-one test for the exterior lights on the Model X. During the test, all front or rear exterior lights will illuminate for 5 seconds and the front or rear body controller will look for any errors. Pass or fail results will be returned for every light. Note: the park lights (hockey sticks) and turn signals will turn on at the same time and the color will be peach (mix of orange and white). This is expected.
