Negative:
-The button to 3 positions: ON; AUTO detection; OFF is not stable to function well
-The Detection AUTO position does not always work.
-The Vis this pilot are not standard (neither flat nor Phillips: they are as flat screw but with a bump in the middle, which cuts the slot), I had to call a locksmith to open and change the bulb
-a compact in width and thickness
Positive:
light not too strong (7w) but sufficient to see at night.
