Is there any problems with applying a reverse V that is <= Vr of an
LED? I'll limit it through a 10K resistor also....
Thanks,

A 10,000 ohm resistor? that seems high for a led forward bias
resistor and any reasonable power supply voltage.
Just play it safe and put a diode in there to protect it against
reverse bias.
Most leds are rugged enough to take some current limited reverse
voltage so it may work fine, but if the led costs money or is hard to
change out, a 5 cent diode makes more sense.

... First of all, while non-electronics types refer to the resistor in this use as a "dropping resistor", that's not really technically accurate: whats actually going on is that you're making a voltage divider network with a resistor in series with the LED. ... By putting a resistor in series with the LED, you're dividing the 24 volts between the resistor and the LED, because the whole idea is to make sure that the LED doesn't get too many volts and blow. ...
