Also, to add some more to Laura's reply.

Allow about 2 hours each direction if driving to
the San Diego area, for the Point Loma lights, and about 4-5 hours, depending on your route, going north to the Monterey Peninsula area for Point Sur; and, if you have the time Point Pinos is fairly close to Point Sur.

Have fun, you'll enjoy all of the lights mentioned. Hopefully you have the time to visit them all.
