Ok I attempted to install mine tonight and I am running into some of the same issues you had. I even have the 3ohm resistors.
OK here are my issues:
1. When I turn them on initially, the right side will fire about 1 second before the left one. They will work and function properly for about 2 minutes.
2. I then started the truck up and turned the parking lights on. Again, the right side fires about a second before the left. Left blinker works, right blinker works. I then put the hazard lights on... they blink perfectly, together, and that part is perfect. Then, after they have been blinking for, lets say, 30 seconds, I turn the hazards off and back to parking lights only.... nothing for about 10-15 seconds. They will barely start to light up (not at the same rate either. one is lighting up a little faster than the other... both barely firing) and then finally light back up to full strength. (sometimes takes up to 15 seconds)
3. I then just had the parking lights on for about a minute or so and one will just shut off randomly. It will then start to barely come on and light up to full power.
I have no idea what to do here. I even relocated the grounds to the fender thinking they weren't a good ground. That didnt help at all. No fuses are blown. It SHOULD work, but it is not.
I really want these to work for me and any help is appreciated.
These are the bulbs I have: http://www.v-leds.com/Exterior-LED-B...72044-1-2.html
What blows is that I didnt want to have switchbacks, i wanted all white that would blink white but they sent me switchbacks... Kinda pissed about this whole process.
