Yes, there is. Take a very close look at the pictures DAE_JA_VOO provided-- See how there seems to be a white + sign under the LEDs? Both pictures you can sort of see it. A lot of LED slots on keyboards have markings like that (mine does; I have a Merc Stealth) actually.
Another giveaway is seeing a resistor attached to a trace that leads to the LEDs.
If you need a detailed guide on swapping out LEDs, check my "Mod Your Merc Stealth!" link in my sig. It shows how to replace the caps lock (etc) LEDs, and the same process would be used on version 1 of the Logitech G15 keyboard.
