I do not do a lot of electric wiring so for what it is worth be careful splicing wires in at this spot or on to this wire or using this circuit for this set up
you are still dealing with voltage and amperage.
As volts go down amperage goes up which can increase heat on the wiring
A lighter bulb may only draw very little amperage yet when you add to the length of the wire and connect Led on then you could drop the voltage and increase the amperage
I tried using the laptop in the Miata after a while I noticed the car start to run rough and the lights seemed a little dimmer.
I was using the cig plug. The inverter and laptop were pulling so much amperage the alt good not keep up
Talking with another Miata owner, He told me about a guy burning a new corvette up by running acc from a cig plug it overheated the wires and gutted the dash
Just giving a heads up to keep in mind
