Depends what I am doing.
Off duty:
Streamlight Protac 2AAA, clipped into my front pocket. Its plenty lumens to light up a yard, room, or vehicle repair. There was talk I saw that the clip makes the light stick up out of the pocket. True, it does, so I moved the clip (see photos).
*edit...apparently I can't post photos??
There is always a solarforce with spare batteries in my truck.
There is also a Streamlight Protac 1AAA in my coats.
If course I have my knife and concealed firearm.
On duty:
Solarforce L2 on my duty belt. Just got an updated LED drop-in, XM-L2 U3. Great light!!
Streamlight Protac 2AA in my trouser "sap" pocket.
Streamlight Stinger HL in the Tahoe in my patrol bag. Another insanely bright light. Also have the good ol' SL20X in the charger mounted on the center console.
Streamlight TLR1 on my firearm.
Am I pretty well covered? :naughty:
