Transformers are used to reduce the voltage in AC circuits. If it is DC (i.e. a car) then you will need a regulator or a resistor.
How much current are you running in the circuit?

Resistance = Volts Dropped/Current
Resistor Needed = 6/1.5
Resistor = 4ohms
However a regulator would be better and it would need to handle 9 watts.
This is from
Power = VoltagexCurrent
Power = 6 x 1.5
Power = 9 watts

Sorry mate i can\'t find one in Maplins. Try popping in to a branch and ask some one in person.
What are you running at 6 volts?
