Hi all,
Apologies if this is the wrong place to post this but I can see lots of similar questions on this forum which aren't a 100% match for my question.
I want to add a new interior light to my car.
I want it to be on either when the headlights are on (power from the illumination circuit of the radio) or when the existing interior lights are on. It is possible that both could be on at the same time.
Both sources are (I assume) +12v
The new light will be grounded to the car chassis via the cig lighter -ve.
Is this possible? How do I ensure that the 2 power sources do not affect each other? (i.e. I don't want the existing interior light coming on when I switch the headlights on!)
TIA
