Signal Lights Hyperflashing Post LED Upgrade

[e.han]

Gents, I've just replaced my factory signal bulbs on my 2015 Genesis sedan with Osram LEDriving Amber and the lights are now hyperflashing.

What are my options to remediate the issue?

1) Can I replace the relay?
2) What can I replace it with? A CF13?
3) Would the CF13 be a plug in fit or do I need to start splicing cables etc?
4) Where do I find the signal relay on the vehicle?

Thanks in advance.

I had a replacement turn signal bulb replaced maybe 6 months ago. A few weeks later the same bulb appeared to be bad. This time the dealer said it was a known harness issue and replaced the entire headlamp assembly. It should be under warranty but I don't know if you'll have the same experience since it sounds like you're using after market parts.

I think I read somewhere that if your turn signals are flashing too quickly then it means the Flasher Relay you have is the wrong type. The Relay your car came with wasn't built for LEDs.

you need resistors if you put LED bulbs in.

Correct. LED bulbs have less resistance and will cause the relay to hyper flash. I think that the relay in the 2 gen. Genesis is integrated into the car's computer system.

You need to install a resister such as this: https://www.superbrightleds.com/mor...yper-flash-warning-fix/190/?accessory_of=4191

Is there a tech bulletin associated with this by any chance? I thought it was just me!
