Hey guys,
just fitted a new relay to regulate flash rate on LED blinkers. No need to work out resistor values, and you can add as many LED's as you like. Its a Tridon SD12...also known as EL12 variable load relay.
I've fitted it up to my 2010 ZX10 and it works a treat. You even get the you bewt tick tick noise when its flashing.
Check it out....any questions just fire away
