Hi guys,
I just install 4 LED bulbs to replace the OEM incandescent bulb for turn signals. All the LEDs come with a built in resistor. Seller marked them as "No hyperblink, plug n play".

Well.... They work perfectly fine when I use the hazardous light. They are super bright and flash in the correct frequency. I also test the turning signal without ignition, they also works fine. However, as I ignition my car on and test them again, they start to hyperblink.
It seems that they cannot work properly when the engine is on.

So what I'm sure now is they cannot be put both front and rear. If you use the combination of one LED and one incandescent for front and rear in the same side, the combination works perfect. However, if you use two LED in front and rear, both LED hyperflash.

Does anyone know how to fix this? It's super weird tho

 

Sounds like you need more resistance since one works but both do not you were probably right on the edge.

 

Get resistors from VLEDS. Or just get bulbs from them as well. You get what you pay for. Vleds are solid.

 

Where did you get them from? I got my turn signal LEDs from iJDMTOY - Going on strong without any issues for 2 years. These don't use resistors but use some type of decoders. Excellent LEDs for the money.

 

I just received my rear turn signals from Vleds I also bought the resistors haven't had a chance to install them yet. Going to purchase the front turn signals with resistors, I also replaced my door lights, trunk light, reverse lights, and vanity lights with Vleds, Bought the Osram CBB 6k hids to replace the originals. I have the front marker lights and puddle lights to do yet also. All Vleds.
