So ive owned my 07 edge since 09. I did hid lows highs and fogs, well I used a relay on each set but the fog lights. Eventually, they started to flicker, only when the fog light switch is off, so I reverted back to stock and they still flicker. Well 3 years later, (I work at a local auto audio and alarm shop now as a master installer) I was testing the circuit that my fog lights are on, and I could get my fogs to turn on with no flicker when manually sending 12v to the fog light wire, well since I did that, I get fast blink any time my head lights are on, now a few days later, they fast blink no matter what. Im assuming I burned out the smart junction box, there is no fuse or relay, luckey for me they arent too expensive to replace just need to check the switch before i spring for a 230 $ computer . Im assuming not using a relay is the culprate
