Any form of 'Cats Eye' (helmet band as an example) does not provide an illumination in the dark on any helmet / hat / equipment that may have this applied.

**Expected Result**
Slight illumination from the cats eyes for anyone in close vicinity to see this. (Helps when moving in single file during the dark, without any lights)
