Flickering LED daylight running lights
I had the same issue when upgrading LED headlight bulbs on my old Tundra.
I discovered there was a continental low level leakage to the driver side headlight when off. It wasn’t enough to light the original halogen bulbs, but was enough to cause the high efficiency LEDs to flicker.
I verified this by swapping back and forth between the OEM and LEDs. Drove the neighbors crazy as it winked through the night. [emoji6]
