I think I need to understand your definition of "strobing". Do you mean they flash on and off for an extended period of time, or do you mean you caught them giving an occasional flash throughout a 24 hour period.2010 Rav4. Keys not even in ignition and I'm getting random headlight and four way flasher strobing. Ocaasionaly in middle of night and battery is then drained. Anyone else run into this?
