We carry one to every car examination we carry out.
Its imperative you have a through look around the engine bay of the car, the condition of the engine components and the condition of perishable items such as the belts and pulleys.
Some things are not clearly viable even in daylight hence we always examine the engine bay with a powerful light.
We also use the examination torch to look under a car to try and spot any fluid leaks, accident damage or signs of corrosion.
We recommend the HeroBeam Light (Click for Current Price on Amazon)
We Love this as its lightweight and compact yet extremely powerful
It also has a handy magnetic end which you can safely stick to the car your examining to free up your hands. There have been endless occasions this light has helped us spot a difficult to see oil leak on the underside of a car, saving us thousands in potential repairs.
