Fast FLash

I am just finishing the bodywork rebuild of my MK Indy. I used to have indicators in nose cone, headlights, sidelights and rears (4nr) with a mixture of led and normal bulbs.

I have smoothed over my nose cone indicators and now i have the fast flash.

How do i overcome this? wire into the old circuit a resitor between the posotive and negative or change the relay?

Either use an LED-compatible relay, or wire in a resistor yes.

Online or Halfords stock them, should say its LED compatible which simply means a chip turns it off and on rather than a bi-metal switch which an LED uses too little power to function correctly and instead behaves like you have a blown bulb.

He's refering to the flasher relay. The one in your link is just a switching relay and not the indicator one

You need an LED compatible/electronic indicator/flasher relay.

Now I guess the real question is the fast flashing a "feature not a bug"????
IE with old incandescent bulbs was the fast flashing there to tell you a bulb had blown? Or was it just an annoying feature

It's a side effect of the way the relay works that if the load drops (due to a failed/incorrect bulb or an led) it'll flash faster. That "side effect" is used to indicate a failed buld though. Electronic relays are often listed with the note "no bulb failure warning"

Perhaps easier to fit a 50 watt 6 ohm resistor in line with the LED
