My understanding is that the 'compatibles' just add a resistor in parallel, to avoid a lamp failure warning - if the LED fails, you would never know.

It happens that Dave Plowman (News) formulated :
Usually for a caravan, it will include all the road lights, battery charge and a fridge supply. Quite a hefty load, plus the wire distance/volts drop, so I have always aimed to wire my main feed as a
6mm or 2x4mm csa.
The method of bulb failure detection varies by manufacturer. Some send a pulse signal to the bulb at about 1Hz. This signal is too brief to allow the filament to heat up. If you fit standard LED's to such a vehicle, the LED will flash when turned off. Not all systems can have a CAN bus defeating LED fitted. That's why it's important to buy from a place that needs your vehicle details.

That resistor could be pulling enough amps to match a 5W or 21W bulb.
Not sure about "canbus" tail but headlamp on Mazda 323F required about
5W load to light the high beam lamp when I fitted HID.
Would be good if they did. But how do I find out?
Might there be a specialist forum for the marque, where you could ask?
Why not use something like this?
I saw that a while ago, and asked them to email me the fitting instructions. No reply!
I've seen the fitting instructions for a similar one (with 13-pin electrics) and that says (or, rather, shows in pictures) to take a live feed from the battery at the front.
Maybe. I've asked in the usenet group alt.autos.hyundai (which carries very little traffic) and have not received any replies.
USENET is as good as dead.
Vehicle specific forums are nearly dead. Far too many didn't have access to proper product data like the FSM and could only repeat ad nauseam "goto your dealer".
Seems that where it's at now are facebook groups. Best of luck with that.
True. Very few youngsters use it. So will probably die out with us old farts.
Dunno about one for current cars, but the classic car one I'm in is alive and well.
A proper forum is so much easier to use. And allows you to search easily for any info. Only good thing about Facebook is the ease of posting pics.
But that means many just post pics of their car in the latest location. So generally of little interest to me. But can understand this since so many only use phones. Which ain't ideal for reading articles.
