Car Emergency Kit

I really know nought about car emergency kit until my Wild Boar tells me how important it is to have it in the car.  They normally comprises of booster cable - which makes up 20%brass and 80% aluminium , carbon steel cross wrench and adjustable wrench, long nose pliers and screwdrivers, air compressor , emergency light with dry battery , insulation tape, warning triangle and automotive fuses.  After realizing how important it is to have it in the car, I phoned Jo and tell her to make sure she has one kit in her car :)
