Sorry to bring this thread back from the dead, but I just put my bulbs in. All work beautifully... Except for one of my amber blinkers in the front. It will blink.. great. But what it won't do is turn on when I turn parking lights on or full headlights. Anyone have any tips on how to remedy this? I tried switching the ambers, and it was still the same bulb did the same thing. Any advice?
Also, install the flasher AFTER you put the leds in. And no you don't need to take any panels out to get to the flasher on gen 1, it is that black box tucked in above the accelerator. Never realized I was missing cargo lights until I saw this post... And I have had the truck for 3 years now. So thank you to all for the help, and hopefully this helps others go through. I'll upload some pictures later this week when I get some time.
