I currently have a set 26V DC running into a light post and want to drop it down to 24V. What would be the easiest way to do it?

If the exact voltage isn't critical, I'd just put three silicon power diodes is series on the +DC wire. If you wire them so the current goes through them in their forward direction, each diode will drop about 0.7 volts. The links below are for a common diode that is good for up the 3 amps of current. Three amps into a 24 volt lamp would be 72 watts. If the light draws more power than that, you will need higher amp diodes.
The first answer from flapjack doesn't appear to be very practical, I would ignore it.

the simplest is a voltage divider. depending on the current you need this can be calculated very easily.
Or a potentiometer ( correct power handling value) configured as a rheostat could work as well.
Or depending on what you have you could use a small step down transformer
