It’s a given that vehicle manufacturers are cheap tight arses, so it is simply the regulations that force them to include such lamp failure warning messages which otherwise wouldn’t exist if they had a free hand.
It’s part of EU & ADR regulations that a vehicle system is meant to warn the driver when there is a globe failure, hence the errors when using a led globe in a system designed for halogens.
The real question is, with these resistors/canbus error cancellers, will you still get an appropriate warning message if a led globe fails? If not, it’s just another nail in the coffin of illegal halogen to led conversions.
Rather than looking at resistors or other cheat devises, the sellers should look at the mechanism that is actually used by the vehicle system to detect a globe failure. It then may be possible to adjust those thresholds, possibly within BMC if that’s where they reside, so that the legally mandated feature still works as intended.
But most halogen/led conversion globe sellers CBF doing things the correct way and just want quick profits like those buying and trying to resell toilet paper.
If your low beam lights are so poor, I’d be taking a completely different approach. I’d be taking the car back to the selling dealer and stating the low beam headlights are so deficient as to not be fit for use and unless they are fixed they can take the car back and you want a full refund as ACL allows. Otherwise, by you doing sus mods, you are taking all the legal risk. Put the problem back where it belongs, with the seller.
