Turn Signal relay for LEDs?

What are you guys using for the relay for LED turn signals? I broke one of my front signals last weekend and I have a set of nice looking LEDs that have been in my bike parts tub for about two years that I want to use.

Thanks.

I just put a post in on this and will remove it if I can get some answers here. My 16's turn signals are apparently run by the computer now and LEDs still blink fast. I guess the only option is resistors at each turn signal?

The reason resistors are used on older bikes are due to the resistance type of flasher units, to mimic the resistance of a conventional bulb since the LED bulbs provide very little. (Or you can use an LED-compatible electronic flasher without adding resistors).

Knowing that, I doubt that adding a resistor would do anything to affect the flash rate, if the lights are truly flashed by the computer on the newer bikes. Unless the lights are just controlled on/off by the computer, and flashed with a conventional flasher. Has anyone confirmed whether a flasher exists on the newer bikes?

I’m working on my 2015 Tiger XCx. I removed the incandescent front turn signals and mounted some nice bright LED signals with 25W 8 ohm resistors in parallel. I tested the operation with the ignition on (engine off) and the new system worked perfectly, blinking at a regular rate. I buttoned everything up started the engine and there is no turn signal illumination with the engine running.

I have the stock rear signals.

Anyone know what the issue is? Do I need a different resistor value, or no resistors at all up front? I want to keep the auto cancelling turn signal feature. Thank you.

One of the Forum members by the name of Ripper has provided some great info, including this White Paper. Take a read. Very helpful.

From what I understand, your issue is related to the single LED in the instruments and how it is wired. Resolution is to add diodes to the instrument indicator LED wiring circuit. There's an explanation in the attached link. Also may want to run a search on "LED indicators".

Good luck. Please share how it goes.

Thank you very much for the link.

I’m not sure this started with the ‘16 models or not. If you have the “i” button then this should work when switched out incandescent to led turn indicators. IGN on but not started. Press the i button several times until it displays “ Type-1”. Then press the button and it will toggle to type 1,2,3,4, IIRC, type-2 is what I set mine to. Once you are displaying type 2, hold it down. Turn off ign and it’ll stay on that setting. Triumph apparently anticipated us paying for the switch over to leds and provided this function. :grin2:

Wow, this is some interesting information. I have LED signals up front and incandescent in back. I wonder if there's a setting for this, or if I'll have to put LEDs in back to use the Type-2. I'll try the different settings and see what happens.

Does anyone know what each number corresponds to? and what IIRC corresponds to?

Thanks!

After a lot of work I've figured it out.
If you use LED indicators on a 2015 Tiger 800 XCx (or Tigers with similar ECU controlled flashers) you have to replace all 4 indicators with LEDs and use only two resistors - one per side. That way you will have the standard flash rate and still have the auto cancelling turn signals, if you have that option turned on.

If you use 4 resistors (one at each turn signal) the resistance is too high and the ECU will go into protection mode and not flash at all. If you do not install resistors you will have a fast blink, indicating the resistance is too low (blown bulb indication).

It does not matter if the resistor on each side is used up front or in the back. I put mine up front and attached the heat sink to the side of the radiator. In back there's more room under the luggage area, but it's mainly plastic, so be sure to mount them on something metal as they get hot.

Hi,
I have a '17 Tiger 800 XCX.

I installed LED indixators today.
After installing only front 2, I had a rapid rate.
After installing all 4, indicators don't work at all. They light up when I switch turn signal and hold in direction, ex if I hold on left then left indicators will have constant light, not blinking.

The i button doesn't give me indicator options, as I have on my Bonnie to switch modes.

Am I to assume modern tiger ECU can't handle led indicators without resistors?

Thanks

Thank you for the link, I still have to do the relay for the LED indicator. They are blinking at light speed...

I changes all 4 my indicators a while ago, but I am looking for slightly bigger indicators for the rear.
Ordered some this week, hope to receive them soon.

Below is the install video for the indicators, some modification and drilling was needed.

If you're going for more visibility in the rear, check out admore lighting.

Over in the Tiger800.co.uk forum "T800XC" has this bit of insight about the 2015+ models:

As with many of the electrical gizmos on the new 800 XRx & XCx they share a commonality with the Explorer since they appeared there first.

In the case of the indicators, the total load per side (not per indicator) must be between approx 1A & 2A for the indicators to flash properly. A load of less than 1A (e.g. when one lamp has blown) will cause the remaining indicator to flash fast to alert you to the fault, as is standard practice on vehicles.

However... a load greater than 2A will force the indicator control curcuit for that side (L/R) to shut down for 25 seconds as an overload safety precaution. The opposite side indicators will continue to work during this period. After the 25 seconds have elapsed the 'faulty' indicator can be used again but if the excess load persists it will shut down again.

Having just installed Rizoma Corsa L + S indicators, I can confirm the need to add resistors. I did the rears first. After the initial test the running/brake light worked, but the turn signals didn’t. All was normal after adding the resistors. The fronts worked fine without adding additional resistors.

I like to post pics, so here are a few..

EDIT: I went back to redo something, and by mistake I discovered that all indicators will work as designed without the resistors after all. I’m not sure why unfortunately. When I initially installed the rears, the stock fronts were still installed and they hyperflashed, until I added the resistors. The difference is now the new indicators are installed instead. Maybe the ecu needed to see the same wattage..?
