No problem Bust....thanks for sharing the info!

The one thing the mod you show doesn't accomplish that I am working on is making them run/turn/brake lights with just a single filament bulb (they talk about doing it with a dual filament bulb which is simple to do) like is found stock on non-Nightster/Iron/48 Sportys. I think mine could even be cheaper when i do the hard-wire kit as I don't need a trailer converter or flasher unit....but we'll see.

I understand that goal. I personally don't need a running light as I'm running a set dual of filament bulbs. I have been using a trailer light module and I have had them crap the bed before.

http://tearitupfixitrepeat.blogspot....aillights.html

Are the dual filament sockets available for a reasonable cost that fit the sportster rear turn signal housing? For Vulcans it seemed like everyone had a set of dual element front stockers from adding a light bar.

Not sure how available the front turn signals are or what they are going for. I know you can buy just the "guts" for about $30 per side....but you might as well buy the HD brake/turn/run module for $60 then. Maybe off Ebay there are a lot....dunno.

The goal is to provide a way to make a cheaper BTR module than the $60 HD unit for the folks rolling around on a Roadster, Custom or Low models. I am still working on a method to reduce the voltage for the running light (again, trying to avoid using a resistor that will generate a lot of heat) and I have to determine the size of the capacitor.

UPDATE:

So I have been spending WAAAYYY too much time on this damn circuit! I probably should have cracked open my old circuits text book from the college days but instead spend hours playing with the circuit simulator online. Been doing a lot of research....found some cool info and tools along the way. Anyways....I think I got it.

I was just utilizing a capacitor to energize the relay's coil but with the help from a friend came up with a better idea to reduce the amp requirements to keep the relay open.

I am going to have to update my wiring schematic to reflect the latest changes....but here is a cool link where you can see the circuit in action and even toggle the brake light and turn signal switches. The site I found below was a great tool to help prove out some of my theories with the circuit simulator. The program has a lot of power to it and allows the most flexibility I have seen for any online simulator. Note that when neither of those are on the running light is on (as shown in the screen shot below). You can run the circuit and as you toggle the switches you can see in the scope below the voltage at the rear bulb. This simulates one side or one light (this requires Java to run).

I couldn't get the link to work right....so unfortunately you have to copy this entire thing below and change the "htp" to "http" at the beginning (it might take a minute for Java to fire up in a separate window):

So the list of components include (for one side) a capacitor, diodes, resistors, relay and a transistor. Hopefully I can make a working unit in the next week or so. The relay matches a standard relay layout:



Next step is to get the electrical components and start building the circuit. I'll get a parts list and prices as I start building...and of course provide step-by-step directions for building the circuit.

Alright....so I have been able to make a functioning brake/turn signal module. This design is based off of the simulation done above with the exception of the "run" light portion of the circuit. If you have dual filament bulbs than this is as simple as running the wire for the running lights to the dim filament and you are done. So this module will suppress the brake light while the turn signal is on:

Here is a quick video of my DIY BT module in action. Notice that the brake light is on steady for the first few seconds then the turn signal is activated. The relay suppresses the brake signal and the turn signal flashes. When the turn signal stops then the brake light automatically comes back on:
