Making a little pun here on the ubiquitous "best XXX in 20xy" videos out there, since the most recent relevant thread I found is already 5 years old.

For the past couple of years I've been driving around with a pair of "no canbus error" T10 W5W led equivalents (branded "Oushi") as positional/side lights that consistently caused a bulb-out warning for the right side. Unless I turned on those lights before turning on the car. Usually I just left them on as ersatz DRLs and each time I went for the controle technique I explained the trick to prevent the warning light.

Didn't want to have to do that this year, plus I noticed some nice chequering of the optical array cover that's probably due to the fact these bulbs heat and are long enough to touch the plexiglass (or whatever substance it's made of).

Long story short, I got a pair of Hella T10 W5W retrofits which came out on top of a big comparison video on YT (done by some Russian guy IIRC). And these clearly don't even try to prevent errors and will also do so with the turn-on-first trick.

So I'm back to regular tungsten bulbs (W3Ws I'm afraid, for now) but I'd be interested to hear about equivalent retrofit leds that are compact, don't heat AND don't cause errors.

(The Hellas found a use in the front roof light; maybe the Oushis can go in the door lights if I can figure out how to remove their covers...)

Try wiring old and new in same circuit. Buy new bulb holder. Spliced in fit LED to headlight. Hide halogen in cover. No more warnings 👍
