Just found the 1 bright bulb and 1 dim bulb saga.... After looking for faulty earths, poor connections and power wires etc etc..... Dumbo here checked the bulbs and hey oh they looked the same but had different ratings !!..... The bright bulb is 12V 130/90W the dim is 12V 75/75W

question.... What is the correct rating bulb I should be fitting ?? (Don't forget I am a hammer man not a sparky ! )
