As Frupi hinted, leds can give problems with the car's monitoring circuits. If the current falls when a bulb fails, it will tell you on the speedo.
Quite clever.... and just what I need, a message telling me that I've got to grovel under the car, exercising unknown levels of manual dexterity, to change a cursed drl bulb.
So, the never fail led bulbs might be thought of as a godsend here - except their exceptionally low operating current makes the monitoring system think the bulb has blown, so you get a permanent nag message.
I suspect that other cars that have these leds have the consumption programmed in, or they are older cars that don't have sophisticated monitoring systems.
