Car companies, starting with Volvo last summer, have laid out plans to electrify entire lineups of vehicles. But the fine print makes it clear that the coming decade and beyond will focus not just on massive battery packs powering electric motors, but also on adding a little extra juice to the venerable internal combustion engine.

Increasingly, that juice will arrive in the form of new electrical systems built to a 48-volt standard, instead of the 12-volt systems that have dominated since the 1950s. Simpler than Prius-type drivetrains and less expensive than Tesla-scale battery power, the new electrical architecture both satisfies the demands of cars made more power hungry by their gadget load and enables the use of lower-cost hybrid drive systems.

    Those things all apply to incandescent bulbs too. LEDs remove the biggest failure point: the bulb itself, plus they eliminate the crappy connection at the bulb itself: with LEDs, you use a much more modern automotive connector to interface the wire harness to the lamp module, instead of being stuck with a decades-old bulb design.

    They've had LED lights on cars now for a couple of decades, starting with the CHMSLs (the 3rd brake lights), and some cars have had LED main brake lights for quite a while too. Have we seen significant failures with these? I doubt it.

    Define significant...

    I've definitely seen half-functional LED lamp modules driving around.

      Well in that case, it sounds like the individual diodes failed, rather than there being a problem with the wiring, connections, etc. LEDs do age and fail over enough time (less if the LED is driven closer to its limit).

        Sometimes an individual diode, more often half a panel... and let's not even get into those LED matrix billboard signs.
