If the brake lights are LEDs, then there will be no change when putting a diode in series. If they brake lights are tungsten, there will be a very slight drop in brightness but not enough to be of concern IME and IMO. A tungsten filament is a very low resistance component that changes with how hot it gets so it is compensatory to a degree (no pun intended about the changing temperature): as voltage is dropped a little bit, the filament will cool down very slightly, thereby lowering the lamps' resistance and allowing more current to flow.

Also, use a relatively large diode and the current drop (not voltage) will be less. For example, pushing one amp through a 3 amp diode will be more restrictive than the same amp flowing through a 10 amp diode. Of course, use common sense and by a relatively large diode, not a diode for a 500 amp welder.

This is one o' dem dare cases where physics is your friend. :-)

My Multistrada has CC built into the ECM. I now wonder how a module like this will effect it.
I'm assuming this is how you would use diodes to isolate the module from the brake light circuit.
Also wonder how the .7 voltage drop across the diode will effect the light.

Good point that I would not have considered. You may be able to delay the onset of the accelerator activated brake light with a capacitor in parallel with the brake light. I have had to do this with several vehicles when converting headlights to HID and the high beam / low beam switch cuts out the low beam momentarily, not a problem for tungsten lamps but it shuts down and re- ignites HIDs every single time the HI / LO beam switch is used.

Brian

The thing I dislike about decelerometer activated brakelights is they activate on upshifts. At least the one I have does. Mine flashes on each shift as I accelerate from a stop. I have the HUB, Heads Up Brake with the helmetmounted LED. It is designed to integrate with the brake system but I opted to just activate the helmet light. Since I also have Hyperlights installed I really don't want to have a full blown light show every time I shift.

There are also products such as the Vololights  https://www.amazon.com/Vololights-Motorcycle-Downshifting-Installation-Waterproof/dp/B00MEQ25X8  and GearBrake https://www.amazon.com/GearBrake-GB-1-Smart-Brake-Module/dp/B00ODR69QK

[This is a good thread, although the "subject" line isn't great/relevant.  Thus, it will be harder to find, later...]


I have the volo lights but aren't sure if they really work because they are behind me.

Adding an extra brake light is an option. I have a Shad 50 tail bag and I could buy the optional
Shad brake light for it. But , it doesn’t look like it puts out much light.
I’ll try some things discussed this weekend if possible, but I live only 5 miles away from the annual Best of the West Rib fest that starts tomorrow and historically, I spend most of Labor Day there, pickling my liver with lots of beer and eating prodigious amounts of some of the finest smoked meats in the USA.

Then there is already circuitry in the brake light that drops the voltage from a nominal 12 volt (which is really between 11 and 15 volts) to the correct amount for the LEDs, somewhere in the 3 volt range. So the diode voltage drop will not have any impact on LED brake light brightness. One of the very nice pluses for both LED and HID lighting- the internal circuitry is already there to convert the vehicles' 'wrong' voltage into a useful voltage for the device. HIDs hold their brightness at 100% until the input voltage falls to something like 9 volts, at which point the ballasts just shut down but the actual lamp (burner) never changes in light output. Same relative situation for LEDs in brake or even headlights.

That is a good question.  I have not seen any post of someone having one yet on a C14.  Based on looking at the photos, I would say "yes" it will clear, with pretty good certainty.

I installed a Supa Brake by Vizi Tec on my Multistrada. It is a flasher and not acelerometer controlled but it is very  interactive and programmable and is plug and play. By interactive I mean that it alters its flashing behavior based on your brake use. I have not had an opportunity to ride with someone behind me to verify that it functions as claimed but if it does I think its a great product.

Silly me, I thought you had it on the Indian, not the fast one!  Anyway, that certainly confirms it fits!  Do you think there is any risk of being cited?  I don't...

I wanted to follow-up this post with my experience with the S2T brake module.  I bought this directly from the manufacturer and had to wait almost a month for it to arrive, since they are overseas.  I should’ve just gone with Amazon and paid a little extra for it.  I did a brake light / tail light conversion on my ‘09 about a year ago ( http://www.zggtr.org/index.php?topic=22821.0 ) and chronicled the install, so I was a little concerned how it would work with in conjunction with this module.  After worrying about how I had everything wired up, I realized that all I needed to do was install it just like the S2T instructions say.  (I am NOT the wiring/electronics wizard that B.D.F. is!)

Install was simple and straight forward.  Took it out for a night ride and it works as it says.  No flicker between shifts.  If I am careful and gradually slow, it doesn’t come on.  If I simply release the throttle, I takes about one second, maybe a little less, to activate.  Essentially, anytime I back off the throttle, it comes on.

All in all, I’d say it was worth the money.   :thumbs:
