Paul Bell Posted September 2, 2020 Share Posted September 2, 2020 Trunk & hood lights have a thing in them that turns the light off when the trunk or hood is shut. Quote Link to comment Share on other sites More sharing options...
Rob Peters Posted September 2, 2020 Share Posted September 2, 2020 If I am not mistaken, it is a mercury switch inside the light itself. If not mercury some other conductive liquid material that when the trunk (or hood) is open the liquid flows to make the connection. The base of the lamp picks up the ground and the wire is always hot. rob 1 Quote Link to comment Share on other sites More sharing options...
