    I have a 2012 Tacoma SR5, 4cyl. I recently upgraded to all LED’s in my OEM headlight assembly. I also added relays to the DRL bulb to prevent hyper flashing. After replacing the main bulb, it WILL NOT turn off. The green bulb headlight indicator is also staying on my dash when the knob is switched to off. When I turn on the actual headlamp they do get brighter along with the green indicator on my dash. I left the truck sitting off for about an hour and they still didn’t turn off. I took out the headlamp relay under the fuse box and they still remained on. The only thing that seems to turn them off is taking out the fuses or just unplugging the bulb. HELP.

    Do you have the problem if you put all the stock components back in? Either you wired something in wrong or the components you installed shorted out the factory wiring.

    When I plug in the original halogens there’s no issues. Is there maybe an extra harness I need? I’m guessing the truck is detecting some type of fault with the LED bulbs

    I’d just return the LEDs and run the halogens. They provide better light output anyway, don’t annoy everyone else on the road like your LEDs will and are actually legal to use.
