THREE!
On a WR! MAN! I bet you have NO problem seeing anything at night....even if it is in the next county!
THAT is what I am doing with the second one I picked up....dirt duty on my WR!
I like them better the higher they are mounted too. Especially in the dirt as it seems to help keep some of the shadow effects better at bay, and allows me to see into holes bettter as well.
