Sylvania 6418 LED Premium Miniature Bulb

Swapping your incandescent 6418 festoon bulb for this Sylvania LED version is one of the easiest interior lighting upgrades you can do. Pull out the old bulb, press in the new one, and you get a noticeably brighter, cleaner white light in whatever fixture you are updating.

The 36mm festoon base fits the same socket as the factory 6418 bulb, so there is no rewiring or modification involved. Sylvania builds thermal management into the LED to keep it running cool and extend its life well beyond a standard incandescent. It reaches full brightness instantly with no warm-up delay, which is especially useful in map lights and trunk lights where you want illumination the moment you flip the switch.

One thing to be aware of: some vehicles have outage detection systems that may flag the lower power draw of an LED as a burned-out bulb. If your dash shows a bulb-out warning after installation, a load equalizer can correct it.
