I bought two 27W LED flood lights. My plan is to run the lights off the auxillary connection and install a toggle switch. Can I use 14 gauge wire to hookup the lights?
the real question here should be the toggle switch load
Your wire size is fine.....
As Skeets said - you can hook a bunch of lights,
but if the current runs through the switch - the switch now can be a problem.
I would suggest that you run the switch on the other side of a relay. The switch simply cuts the relay on.......
think about it this way, would you want all the starting amps of your car/tractor running through the key switch???? Thus we use a relay...or in this case a solenoid!
Relays are cheap and it will protect the switch.
