    Start with the harness. Sounds like a loose connection. Could also be a bad relay. Turn the lights on and work your way through the harness at each connection.

    Yeah I. On my way out this morning to check the conne8but it didnt seem like that when it happened. It looks like something going out as it will just cut of for 1 blink then back on for a bit and so on...very annoying. Looking at hi output bulbs for my factory housings now as well....ffs

    Cuts out when you turn your blinkers on? This is a known issue and I think toyota fixes it with a new switch stalk. I had it happen twice, when turning left, about 1 year ago both times within a week. No issues since and I didn't do anything to remedy the problem, it just stopped doing it
