Installed switchback running lights. Not working properly.

Hi,

I installed these switchback LED bulbs from eBay. I also installed the EP28 flash relay to bypass the hyperflash.

The hyperflash fix works for sure. I tested a before and after. The problem is that the LED lights (with the headlights active) have the white LED on, and the amber just flashes very dimly regardless if the turn signal is on or off. With the turn signal on, the white LEDs would remain on, and still, the amber just flashes (the white kills the usefullness of the amber). A few times with the turn signal on the white LED's were off and the ambers just flashed, but when the turn signal was switched off, the white did not return.

Sorry if im confusing you, but any idea what is wrong? Also, both the turn signal lights in the spedometer cluster were dimly lit and would grow brighter/dimmer randomly. Did i buy junk or am I doing something wrong?

2001 GTP btw
 


Anyone have some input on this? I contacted the seller and they said to just make sure all pins are connected properly (which I believe they are).
 
It's eBay just freak out a little more give me a neutral rating, I recently bout 20$ LEDs done lights. One flickered I *****ed I they full refunded me. Just keep talking to seller
 
Look up a thread by COPGTP, I think your bulbs are like my Regal, they are not a normal bulb, you may have to turn the bulb around in the socket for the pins to line up right etc.

EP28, I thought it was EP29 with a pin cut?

I tried switching them around, but they do not turn on. I am going off of this tutorial, thats why I purchased the EP28

Make sure you have leds in the 194 bulbs too.

I do not. There are halogens in the 194 socket. Did not know you were supposed to have LEDS in them. Do you think that may be the problem?
 


Have you had any luck fixing this problem? When i activate the turn signal the white stays on and the amber flashes but you can barely see it.
