Do I need two of these? One for the front and one for the back turn signals?

Using a stock tail/brake light. Upgrading to LED turn signals. Just looking for some discussion on load equalizers...

 

What bike?

 

Just use the Badlands Module, if the bike is CanBus it doesn't need equalisers.

 

 

My bad. '94 FXDWG

 

Ok, those where still pretty basic systems back then, and the load equalizers today have much better components that handle the loads.
Best bet is to just try.
Install just one set at a time, if your system handles one set then you'll know.
My guess is that one of the better grade equalizers that plug into the rear harness will handle enough of the load for all four turns.
I added an LED brake/turn light and the equalizer that came with that kit did and does handle the load for itself and all for LED turn clusters I added later.
What I'm kind of saying is a $75-80 equalizer will probably handle the load better then the $15 one. Another route is to direct wire a resister to each signal, they have those available too, it's just about how far your understanding and involvement of the wiring want's to go.
tip;
You can run into issues with the left rear turn signal that's unrelated to load, HD ran/runs those wires with a reverse polarity that doesn't matter to the individual incandescent bulbs,, they don't care with side is +/- when isolated,, but some LED cluster type bulbs need + to be on a specific side-- if it's reversed they don't work.
If you do install and have trouble with that rear left side,, come on back here and we'll walk ya through it.

 

You will need an equalizer for each pair of LEDs you install unless you are using a turn/run/brake module, then you will need at least one equalizer circuit for the front turn signals.

You can get load resistors at a local automotive store and go that route but you will need one for each light.
