FLIR systems make a range of night vision cameras that can be added to your boat (pictured), car or used in a security context.

FLIR (Forward Looking Infra Red) cameras let you see in total darkness. I can see this being handy in some situations, such as marine navigation - they don’t exactly put street lights on the ocean!

It’s also offered as an aftermarket addon for cars. FLIR systems can see further than conventional headlights so you get more warning of obstacles ahead. It could also offer you an advantage in foggy conditions too - visible and IR systems react differently to fog so you’d get a second view of the road.

You’re looking at around the $4000-$4500 mark fully installed into your car, unless you have a recent high end BMW in which case the factory option is "only" $2500. Pricey, but very neat!

Now, if only somebody would combine this with a head up display to superimpose the night vision picture on the windscreen. That would be pretty cool. BMW, are you listening…?
