Help With LED Headlights

I just installed LED headlights on my 2017 that previously had the regular old halogens. I put the headlights on with no problems connect all the parts of the harness and got the headlights running perfect. I tested both by simply using hazards and they work great. I only realized once I put my left blinker on that it goes super quick. The right one was fine for a while, then suddenly also started going quickly, but then switched back to normal blinker speeds.

I am super stumped on what is going on. The left only goes fast when using the left turn signal and not when using the hazards.

Has anybody had a similar issue or know how I can fix this? Thank you!

 

Oem led headlights or aftermarket?
You need resistors if you are using led turning bulb to prevent hyperflashing. Put back the incandescent bulbs and see if it cures the quick flashing. If it did, get some load resistor for your led turning bulb. Or get the led bulb that has the resistor build in..

 

What wiring harness are you using? If it isn't ihacker, it should be.

 

Welcome to the forum.
I concur with the 2 posts above...

I'm guessing they are aftermarket and have an internal LED turn signal.

I like VLED for resistors..

They are aftermarket. But i bought them because they were “plug and play”. It’s not just one bulb either, it’s the whole flashing turn signal sequence. Thanks for your response!

 

What’s the brand? Sounds like you should return them.

 

Vland, someone told me they were really good. Should have know based on the price that they would suck.

 

There are a couple threads on this issue with after-market headlights.
They may come up in a search..

 

If they came with the second harness for the DRL that's probably why. The DRL delete module from Morimoto fixed the hyper flash on my headlights. Some companies sell the headlights with an optional resistor.

 

Better send them an email for support. To see what they can do for ya.
