I sent my brother in-law in Iraq a Streamlight 4AA back in March or around there since then 2 switches have gone out of it. Streamlight is very good about sending him switches for it but it takes 2 to three weeks to get there. Is there any other switches besides streamlights that might work with this light that I can send him? Any other suggestions? He really likes the light he has others but he uses it the most.
