I want to put LED lights on my 2009 Heritage. Planning to switch over the headlights, spots, turn signals, tail light, and fender tip lights. My bike already has the module that makes the rear turns act as running/brake/turn signals and it flashes the brake. That module was on it when I bought the bike, so I don’t know exactly what it is.

Ive read about possibly needing a load resistor if the turns flash too quickly. I understand the concept, but not the details of where and how the resistor is installed. Are there aftermarket flashers designed to work with LED turns?

 

I have the Custom Dynamics triple-play turn signal unit, works fine with my LED's. I think they also make a load resistor unit. They also make high quality LED's, though I have LED's from Paradise Lights, who I also recommend. Anyway, check Custom Dynamics website re the load resistor.

 

Custom Dynamics has stand alone load equalizers for pre-Canbus bikes with LED turn signals, and stand alone Run/Brake/Turn turn modules to make your rear turn signals function also as running lights, brake lights AND turn signals...

They also have the triple play module, mentioned by "crtfibl", which does both jobs in one module...

The two module set-up just has both modules piggy backed together in the main harness between the harness/rear lights connector under the seat... Obviously, the Triple Play mounts in the same location, but it is only one module..

Just FYI......

They may have fixed their fitment charts, as they requested photos and also called me about an issue I reported to them with the Triple Play module.....

I ordered the Triple Play module for my '03 EFI Heritage, per their fitment guide... It WOULD NOT FIT between the battery and the ECM (electronic control module), because the Triple Play module was too thick. It was also too thick to fit along the sides or front of the battery....

Luckily, I also have an '01 Springer that had their older (and thinner) set-up with two separate modules, a R/T/B module and a separate load equalizer module.....

The bigger Triple Play module was able to fit on the '01, because it has a carb. The Triple Play module did fit underneath the ICU (ignition control unit), because it is smaller than the Heritage's ECM....

I mounted the two separate, smaller modules on the Heritage. I split up their mounting locations. I put one between the battery & ECM and one tucked in front of the battery.

Hope that made sense...

I just wanted to share the issue I had with the Triple Play module fitment on an EFI softail. The Triple Play module is a good, all-in-one module, working just fine, plug & play, on my '01 Springer...

 

I did Custom Dynamics all the way around, well worth the money, if you decide to change the bulbs in the passing lamps you'll need to change the lamp housing if you have the sealed beams. Also Eagle Lights makes great kits for the head and passing lamps. I may end up that way, I had on on my Dyna and liked it.

To directly answer your question the resistor goes in parallel with the led such that the two together draw a similar amount of current as a bulb to "fool" the turn signal module.

Most of the pre made units have an in and an out connector so it can be easily connected inline but internally it will be in parallel with the led light.

 

My advice! Contact Eagle Lights! They are very knowledgeable, They answer all your questions and their lighting and prices are fantastic. Lifetime warranty also that can't be beat!

 

Have you ever thought of using an LED strip? The main advantage of the LED strip is the ease of installation because it is quite simple to install. Besides, any motorcyclist can easily do it; for this, there is no need to carry a vehicle for maintenance. Another advantage of such a tape can be considered durability, and because it is quite cheap, you can change the backlight of the motorcycle at least every day. For example, I bought myself some of these tapes https://www.vont.com/product/smart-s...-strip-lights/, and it looks cool.
