West Yorkshire Police have set up an incentive for motorists to deter thieves.
They sell the Thatcham rated 'Disklok' at cost price.
£30 Small (Most cars) - [Halfords £59.99]
£45 Large (Vans etc) - [Halfords £79.99]
I bought mine from the Holbeck station but I believe Morley stock them aswell.
They did only have 6 left (small) unsure how many large.
*Sales are limited to two per person.
