Had a few minutes tonight. Pulled out the air intake to get some good access to the headlight housing. Tapped, banged, bumped the assembly and module underneath and couldn't replicate it. Disconnected and reconnected the connector as well. Tapped the wiring that I could see in the engine bay too to see if there was a loose or shorted wire. Not a flicker. Came home and sure enough saw the flicker as I braked into the driveway. So weird. I'll plug in the computer on the weekend and see if there are any codes.
