    Need some help I have the protuninglab Tacoma sequential head lights, and the turn signals both LH/RH aren’t working. But what’s weird is when I turn the hazards on they work. Is there a different fuse just got the front turn signals? I’d think the fuse would be for turn signals/hazards so I don’t think it’s a blown fuse.. any help would greatly be appreciated

    Edit: when I turn the LH or RH blinker on I do get a fast flash on the dash and my rear signals do work. Just wanted to add more info

    The 2016 diagrams show that they do indeed use the same Hazard fuse.
    Other than that, I can’t help much.

    I had a similar problem when I installed some vled rear signals. The problem is that the turn signal measures resistance to see if the bulb is burnt out and led lights have much less resistance compared to the stock bulb and the system thinks its burnt out, thus the fast flash. I needed to install 4 ohm resistors in the circuit to get it to work right.

    so I’ve ran these headlights for 2 years now and they worked fine up until a few weeks ago, the RH stopped working then a week later the LH. So I don’t think it’s that unfortunately

    Then there is something probably wrong internally with the led lights, most like there is a resistor in there to make the correct resistance that is now fried.

    the vled resistors are 2 inches by 4 inches in size and have aluminum fins to reduce heat buildup, there is a good chance whatever resistor is in there isn't as robust.

    Yeah I’m kind of thinking that too, I’m in contact with pro tuning lab. Just waiting on them to email me back

    If you still have you stock lights you could plug them in to test to confirm there is nothing wrong with the truck itself.
