Deer deterrent set back

The new L.E.D. deer deterrent is holding up well under some heavy winter weather, but I've decided to shift directions in this department and try a different approach.

A friend pointed out that deer are color blind and may not be seeing much of anything in that moving pattern of light projected onto the barn wall.

I still think there may be a deer deterrent use for these night lights by simulating movement in the dark somehow. Clearly I need to do some more tinkering with this concept. I'll continue to listen to my friends that hunt deer for any further behavior tips I can adapt to this low tech solution that can prevent your garden or flowers from becoming a daily deer snack.
