So as many of you know, I've installed LED strips as my daytime running lights. They are wired into the parking lights.
Today I noticed that on one of my strips, 3 LEDs are blinking while the other 9 are on. It makes sense that 3 are blinking because they're wired in sets of 3s. What has me stumped is that this happens ONLY when the engine's running. If I turn on my lights with the engine off, it's all fine.
Does anyone have any thoughts about what could cause this?
