Poison Spyder LED marker lights not working

[Patrickmcminn]

I bought a pair of the poison spyder 3/4 inch led marker lights to replace my blinker due to tube fenders. I wired them up and turned on my headlights and the driver side marker worked but the passenger didnt. After that I turned on each blinker, the passenger works but the driver does not. Has anyone else installed these lights? If so has anyone had this problem?

Since they are LED turn signals, you'll need an LED flasher relay for them to work properly.

This is the one I have always used:

will that work on my 97 tj?

Also, LED markers won't work in place of the factory incandescent side marker lights in the fender flares without some re-wiring. This is due to the fact that they use a "floating ground". There is a thread in which I believe @cr0sh figured out the solution.

Yes, but also see my other post I just made above.

It's just for the front marker lights and blinkers

Yep, those front marker lights have a floating ground, that's the issue. They don't like LEDs.

so I'll just have to rewire the ground?

I'm not entirely sure. In that thread above I think he mentions how he solved it.

I'm terrible at wiring, but I suspect you'd have to do something like that.

 

[Patrickmcminn]

also where does the 4 pin flasher relay go? I dont think there is a spot behind my steering wheel

LED bulbs are also diodes so they cause problems when installed into the side marker circuit which requires the bulb conduct current equally in both directions. LED bulbs only conduct in one direction. The current flow through the side marker circuit reverses when the headlights are turned on/off.

The suggested EP26-LED flasher won't help since it's purpose is to slow down the hyper-flashing speed that LED turn signal bulbs can cause.

Reversing the wiring to an LED side marker bulb can help it work better when the headlights are either on or off but not in both conditions.

If you are dead set on using LED bulbs in the side marker locations, the only real fix is to install a bridge rectifier onto both sides. That will allow the current to flow both directions through it while powering the LED bulb with the correct polarity so it works properly with the headlights on and off.

I'm not replacing the lights in the flares I'm replacing the front lights with the small round led lights that you have to use with tube fenders

It's not required to use LED bulbs in front of Poison Spyder's fenders, I'm not. I moved that bulb location to the bottom of the grill and used the OE incandescent bulb in its factory housing inserted into a JK enclosure. You can see the empty light hole in my PSC fenders. Though even there you could use an incandescent bulb.

okay I see

I found a wire harness that changes from a + - - front headlight harness to a + + - harness. Said to cure all the LED issues up front. They seem to have good ratings on Amazon. This may or may not fix your specific problem, but it claims to.

Could you post the link on here?

 

[Jerry Bransford]

What does a headlight harness have to do with his turn signals? Not to mention the polarity going to the headlights is already correct for LED headlights.

 

[Goatman]

People claimed it made the headlights (both LED and bulb) brighter. Or cured signal lights from acting funky. I am in no way endorsing this product. Mearly saying it exists and some flame it helped them.
I would post a link, but honestly have no idea how. I can barely get a photo to work. And every F-ing time the stupid phone updates it seems like I have to find out the new way to do something. I am old! It takes me forever just to make my big fat thumbs hit these tiny little letters on the screen. Just recently figured out the picture part. (See picture of old man above)

I am having a problem with these as well. They work like they should but on one side the green arrow on the dash is solid. This is only when the marker light is on. They are wired the same so I am not sure why one side works proporly and the other does not. I've heard something about useing resistors but I am not sure. Any thoughts?

Did you ever find a fix for this because I having the same problem.
