The Mighty Dot a new hi-tech vehicle security marking system is to be made available as an accessory by Mitsubishi Motors through its UK dealerships.

Able to be fitted on new or used cars, the Mighty Dot is almost impossible to remove, helping to protect against car jacking and ringing.

The device will cost £180 per vehicle plus fitting and it will also be fitted as standard on the Mitsubishi Lancer Evolution VII supercars at the company's Portbury docks import and preparation centre.

Mitsubishi director Stephen Blackburn said: "Today's thieves use sophisticated measures to get around most security systems. They even steal the keys to undermine the effectiveness of the vehicle's engine immobiliser.

"The Mighty Dot process should deter the thief from taking a vehicle that has its own unique fingerprint. Complete, or in bits, the vehicle will remain traceable it's not worth their while."

Managing director Craig Simnett said: "Mitsubishi is one of the first motor manufacturers to introduce the product. With car crime on the increase, we are pleased that it will be available to a wider range of consumers."

Mighty Dot works through the application of a unique spray of 5,000 polyester microdots to the engine, chassis and body parts.

Each dot is laser-etched with a PIN number, easily visible under UV light. Once the product has been applied, the PIN number is held on the international security register, enabling simple identification of vehicle parts.

Mighty Dot has obvious advantages for customers: for a relatively low investment, customers' vehicles can be protected against car jacking and ringing for the lifetime of the vehicle; and the product is applied at the dealership while the owner waits.

A Mighty Dot application takes 10-15 minutes and, once the vehicle has been treated, the dealer attaches stickers to the windscreen and side windows, which act as a deterrent to thieves who recognise that they are no longer able to change the vehicle identity without being caught.
