I recently upgraded my headlights and tail lights on my 08 f150. After having to wire in another pigtail for the left side, my lights aren't that bright anymore, and when I use my blinker, both sides come on. It's as if I'm turning on my hazards. I wired in the replacement pigtail the same way the old one was wired. I was using LED bulbs, but got tired of the fast blink when using the turn signal, so I went back to the original bulbs. Any fixes for this?

 

You need to get a flasher for LED bulbs (EP27, I believe), or you also wired the pigtails incorrectly.

 

Yep, EP27 will fix hyper flash with the LEDs. And, I agree something is wired wrong.
