All right! Are you swapping the rear signals for led's, or are you swapping the front signals for led's?
If rear: The bulb in the headlight bucket needs to be positioned (and fixed in place) so its heat doesn't melt insulation off wires. One stock bulb (per circuit*) will do, you need a draw on the circuit to slow down the signal rate from removing the incandescent bulbs (or use a Kuryakyn LEQ). Unless you removed the brake light, you already have a rear running light. If you want the rear signals to be running lights also then you'd have to check the led's you bought to see if they are wired for two circuits.
If front: The bulb in the headlight bucket needs to be positioned (and fixed in place) so its heat doesn't melt insulation off wires. One smaller bulb will do, you need a circuit to drain excess power to avoid the click of death from removing the front running lights. You might also use a Kuryakyn LEQ to maintain flash rate if desired. You can't have red lights up front or people will think your front is your back and you are going the other way! Many don't have front running lights but most local laws require them, its your call. You'd have to check the led's you bought to see if they are wired for two circuits, which would give to front signals and front running lights.
A quick search for "LEQ" or "LED" or a quick run thru LIGHTS in Popular Mods will yield a lot of helpful information!
* thanks alan, I thought that was obvious but maybe it was not.
