    Subtle Power


    I spent more time confirming the mounting locations than I did installing them. The lights installed quickly and securely, and adjustments were made just as fast. Testing their sensitivity ranges was fun, as well. Time will tell how well they stand up to the seasonal weather, but I have faith they'll earn 5 stars.
