I personally use the Cluson Lazerlite with the Blazerlite Upgrade with rigid 12v 10 amp Shoulder pack,does the job perfectly especially with the upgade which Im guessing is a more powerful bulb..Ive used the striker 170 in the past.
Fine looking pups mate,,,If I didnt have a litter on the way myself I would of been intrested in one for sure,,Shouldnt have any problem finding these a home,,ATB
