    Hi everyone. Recently bought some Amazon special LED lights (https://www.amazon.com/dp/B09ZNT6DNY?ref=ppx_yo2ov_dt_b_product_details). They are super bright and seem like decent quality (so far). I have them wired to the battery with a relay getting its signal from a piggyback off the high beam fuse. They come on when the high beams are on and everything works great. However, when my bights are not on, occasionally, the LED lights will flicker as if there is a voltage/current leak? I've swapped the relay and checked my grounds. I'm thinking I may need a diode to stop unwanted current flowing in the circuit or a load resistor so the LEDs act more like the halogen bulbs that the brights are used to switching on. Just wanted to see if anyone else ever had a similar issue and what they did to resolve it! Thanks!

    If they’re on a relay they should be isolated from the high beam circuit.

    I’d try disconnecting the relay coil from the high beam circuit. If they keep flickering, something is up with the relay or the wiring. If they don’t, then you’ve got current in the high beam circuit that is activating the relay.

    Is your relay grounded?

    Yeah, relay is grounded. With the high beams off, all lights off, truck running and e-brake off, the high beam circuit I’m tapping into still is giving like 7.5 amps. Enough to make the LEDs flicker I suppose.
