Adaptable fixture mount sensor for vapor tight light fixtures

A method of mounting a sensor assembly on a corresponding light fixture having a fixture opening defined therein, the method comprising:

• for a first light fixture having a gasket lip extending adjacent to a sensing area of the sensor assembly when the sensor assembly is mounted on the first light fixture without a spacer:
• (a) detaching a first mount portion from a second mount portion collinear with the first mount portion at a break point defined between the first mount portion and the second mount portion;
• and
• (b) removably connecting the sensor assembly to the light fixture by inserting the second mount portion into the fixture opening;
• and
• for a second light fixture having a gasket lip extending into the sensing area of the sensor assembly when the sensor assembly is mounted on the second light fixture without the spacer:
• (c) placing the spacer that is longer than the second mount portion onto the sensor assembly such that at least some of the first mount portion extends beyond the spacer;
• and
• (d) removably connecting the sensor assembly to the light fixture by inserting the first mount portion into the fixture opening.
