This could be extremely dangerous. When the vehicle is immobilised, does it retain power steering control and brakes? It could cause a huge accident.

I'm pretty sure you can't have blue flashing lights on a vehicle if it's driven on a road - http://www.police.govt.nz/faq/is-it-true-that-only-emergency-vehicles-can-use-red-and-blue-flashing-lights . The definition of a road is very broad - <a href="https://www.drivingtests.co.nz/roadcode-questions/car/core/whats-the-legal-definition-of-a-road/" target="_blank" rel="nofollow">https://www.drivingtests.co.nz/roadcode-questions/car/core/whats-the-legal-definition-of-a-road/</a>
So, if they're just used in a warehouse blue lights would be fine, but you wouldn't be able to use them in a right-of-way, public car park, footpath or road. Why aren't the using the standard orange flashing lights which are the usually hazard warning beacons?
