i have used a solid state DC DC relay for switch on and off my cars light. as usually the light remain off and when given the command to relay it completes the circuit and the light is on.
now i want to reverse the situation .. the light should remain on always (as soon the ignition of the car is switch on) and i can swicth the light off ..and on it again according to my desire.
how i can do it. will the relay i used work.? or i have to use any thing more. what will be the circuit diagrame for this type off cooncetion.
