You might want to replace the LED with a normal silicon diode since if I were a piece of shit TV company I would measure that circuit as a voltage divider, and for a complete circuit. No current flow and no 0.6V drop, and that means I activate my out of warranty self lobotomize routine.

    That's not something I would have considered and thank you for pointing me in the right direction. Now I know about silicon diodes.

    Because this reminded of it: For a similar reason, and if you own an older vehicle, you don't want to replace the warning lights (battery, oil, engine/MIL) with LED bulbs. Or you'll need "error free" bulbs with built-in parallel resistors. LED gauge lights are usually fine but, on a lot of vehicles, an incandescent bulb is expected on the warning light circuits. If you replace, for example, the battery bulb with an LED - the alternator might not engage as it should, because there won't be sufficient current for it to do so, and your battery could drain despite a running engine.

    (I'm far from an electrician, nevermind an automotive one, but I did a lot of research before upgrading/replacing my burnt out dash lights and that's a mistake I would've otherwise made)
