Hyper flashing blinkers

[Evan_B]

So I have recently purchased new head lights from Amazon on my 2014 SLT GMC sierra, after installation i have noticed all 4 of my blinkers stay solid and after turning on the left/right blinker all 4 flash….what should i do????

Your new headlights may have a wiring or compatibility issue. Try these fixes:

1. Check wiring – Ensure all connections are correct.
2. Add resistors – If they use LEDs, install load resistors or an LED flasher relay.
3. Check grounds – Ensure proper grounding.
4. Reset system – Disconnect the battery for 10-15 mins.
5. Test with old headlights – If the issue disappears, the Curve Rush new ones may be faulty.

If the problem persists, contact the headlight manufacturer or a professional.

Sound like a writong or compatibility issue with the new headings. I'd doulbe check the harness connections and see if you need a load resistor stickman clash!

I would try #5 first to see if it's the new lights or something else.  If everything returns to normal, then it's the lights.  If it continues to hyperflash, then I would try the other options listed.  Just my 2 cents....
