Hi,

I have replaced my indicators with LED some time back on a K3 GSXR600, and got the fast flashing which actually just scrapped past on the MOT.

I've replaced the relay with one from eBay at the time, this did cure the fast flashing but sometimes the indicators would just stop working. After contacting the seller he sent out another one and it did exactly the same thing so I gave up and put up with the fast flashing on the standard relay.

Come today I've tried to sort it out again, I've now tried some wireround resistors in from Maplins put them on each wire of the two back indicators. I've tried a 10watt 6ohms resistor and a 10watt 20ohms resistor, and amazingly it's make no difference what so ever. So then I tried doubling the 20ohms resistor on one indicator and no resistor on the other and still no luck.

Anyone with a GSXR600 who has sucessfully put in LED indicators all round and slowed down the flashing?

Cheers

You are putting the resistors between the indicator wire and earth and not in line with the indicator?

Buy a digital (LED) flasher relay. About £10 and will cure your problems.

This.

You need an electronic flasher relay. Thumbs Up

I have two rear LED indicators, along the wires for each is a black rubber block, with a resistor in it, I presume.

Two, one for each indicator.

Thanks for the replies, the flasher unit is integrated into the side stand relay and all sorts on the GSXR which is a pain. It's not separate. But I suppose I could get a 2 pin flasher unit, and feed the indicator wires into the flasher unit instead of the original relay.

Do you think any 2 pin relay would do? I was looking at this..

No a 2 pin relay won't do.

A 2 pin relay is flashes due to something called a bi-metallic strip, the current flow heats the strip which then bends, breaking contact and turning the indicator off. As it cools, it straightens back out again and remakes the electrical contact, indie comes back on and the cycle starts again.

The problem with these is that if you don't have exactly the right load what they are designed for, they won't be heating/cooling at the right rate and the result is indicators that are two fast or two slow.

What you want is an electronic relay, where the flash rate is set by the electronics in the box and is not proportional to current flow. With one of these you can run LEDs, big bulbs or little bulbs etc etc and the flashing rate will stay constant. These electronic relays will have 3 (or more) pins as there needs to be a constant ground for the electronics inside to function.

So there will typically be 3 connections:

A 12v positive
A ground
A "flashing" output - in reality it's a live being switched on and off at a set rate

Then this flashing output gets routed to the left of right side indies by the switchgear switch.

Personally I wouldn't buy a relay, I'd knock one up from the shizzle in my electronics box. That's just me tho Wink

Could you please make up a paint pic of how you have wired up your resistors?

Do you know about resistors in series/parallel? Not insulting your knowledge, just most people don't know naff all about electronics/electrics.
