Laser Guns at night

[dempsey]

I bet everyone knows the answer to this except me, but is it true that mobile laser speed guns can't be used when it's dark?

nope they can be used.
however the operator is ment to form prior opinion of speeding before their use - of course that is always done they never aim at everything do they?

They've got laser guns now, as well as speed detection devices? Cripes.

The laser speed meters work OK. The video used in mobile camera vans doesn't (as a good general rule). No video => no record of the number plate => no convictions.
