Do you have a control box for them or do you want them to come on only when the doors open.
Yes sir that will work. SPDT stands for single pole double throw on a switch. On the back of the switch it will have three blades (poles). The center pole would be the common (in my case the ground from the light strip) and the outer two poles are what the center pole will be connected to dependeing on switch position. (again, in my case one goes to both door switch grounds and the other pole goes to a chassis ground).
