KTM 76014937044 LED indicators

Post by Hardyrider » Sun Oct 14, 2018 12:09 am

So I’ve purchased a set of the KTM LED indicators from Gear 4, beforehand I emailed them asking if this kit will fit my 2013 SMT, which came back confirming they will.

https://www.gear4motorcycles.co.uk/part ... mcr-08-on/

Ordered and went to fit them this morning, for the life of me can’t see the flasher relay I need to swap over to the new one to slow down the flash rate on the new indicators.

Can anyone point me in the direction of it please.Image

Hi HR

The blinker circuit is integrated into the hazard light switch.

I thought it had to be something like that after I couldn’t find the relay, I’m thinking of getting some in-line resistors like these to slow down the blinker rate?

Also looking at the supplied indicators there’s something in-line on them as well.....

I could be wrong, but in this modern age, I would have thought the blinker circuit would be a digital timer controlling a transistor. The timer being either a micro controller or a programmable configured integrated circuit (FPGA, CPLD etc). All these would be independent of the load (ie: the LED and any resistor in series). If this is the case, then I think it would be impossible to reprogram the blinker so that it's rate is slowed down.

Interesting, those came with already build-in resistors. I had no problem installing them on my 2015 SDR. No problem with flashing speed

Not sure. LED's need a series resistor anyway (as a constant current source) as the hazard circuit board won't have that. Incandescent bulbs generate their own resistance when they illuminate.

If you want to experiment, buy a LED and 100 Ohm 1 Watt resistor and some 22 AWG wire. Connect the LED and resistor in series, then connect it to your blinker circuit. Note the blink rate:

Next, swap the 100 Ohm 1 Watt resistor with a 330 Ohm 1 Watt resistor. Connect up and note the blink rate.
