You need to dim down your pin light, and get a stabilizer mounted light.
I put a small piece of electrical tape on the end of my pin light, it blocked a little more than half the light coming out of it. No more washing out the pins. Now I have the Spot Hogg rheostat light, on low setting it is perfect for night hunts.
To light up the pigs, I use an Elusive Wildlife XLR-100 in green. I use the low power setting most of the time. It screws into the stabilizer hole in the riser, and the switch sticks with a piece of Velcro near the grip.
There have been a few folks fiddle with a bow mounted laser for pig hunting, but I have not yet run across a commercially available one just yet.
A laser is highly illegal in Texas for any game animal, keep that in mind.
I also use this light on my AR. Works out pretty darn good.
