Question Solid state device to make a circuit when 10 volts are reached

I am looking for help with a solid state unit that will allow my 12v DC motorbike lights to work after 10 volts are reached from its alternator.
Thanks...

I would probably use an Arduino.

You can build such a circuit with transistor, MOSFET or Op-amp with additional resistors and diodes. However, considering price of arduino or other micro controllers these days, I would say go for arduino as well.
Arduino nano or it's clones will be more than enough to you what you need and you will also need 5V power supply (a cheap DC to DC will do).
You can get clones without USB port if you have size restriction, but you will need external USB to UART adapter (or make one with arduino uno) to program them.

If you never used arduino before, I suggest getting arduino uno as well and play with it first.

You want the lights to work when the voltage drops to 10 volts or lower, or when the voltage is 10 volts or higher?
