possibly,

but then again, consider this:

Your wife/girlfriend borrows your pride n joy to go out for the evening and this happens, your wife/girlfriend in seeing the flashing 'wig-wag style' lights and thinking its a proper copper stops and pulls over.
she's then attacked and the car's nicked.

it doesn't even bear thinking about does it.....

if anyone can, feel free to post it on to other forums they are members of, its shit like this that people need to be aware of
