Everything is ridiculously expensive in the UK

The Pak-Lite is certainly cheaper than a Betalight at around $100 and you can get the Pak-Lite 'Super' in the US for around $20.

Betalights are great in the tactical role but not much use in the civilian survival role.

I used to carry a betalght in my combat jacket for tactical map reading, reading documents and things like changing radio frequencys. They used to be used as tac signs too. You still had to carry anouther means of signaling though.

I have a PAL light and don't have that problem.If you hold the button down till you see it flash twice,it is then off(or in it's constant on feature.I do like the always on feature and it sits by my bed.In a power outage it is the easiest flashlight to find in the dark.Once while my DW was cleaning she knocked it off the night stand.I finally found it at 2A.M.when I got up to take a standard nightly walk.
