2021 Chrysler 300 Headlight Bulb Size & LED Upgrade Guide
The 2021 Chrysler 300 headlight bulb size is H11 for the low beam and 9005 for the high beam, with H11 fog lights on equipped trims. As arguably the last true rear-wheel-drive American luxury sedan still in production, the 300 stands apart — available with a 5.7L HEMI V8 on the 300S and 300C trims and carrying a presence on the road that few modern sedans can match. Upgrading to 2021 Chrysler 300 LED headlights sharpens that presence after dark with a modern white beam that complements the car's bold styling. HID Nation kits are plug-and-play, ship free, and include a lifetime warranty.
Best Headlight Upgrade for the 2021 Chrysler 300
The 300's projector headlight housings were designed to produce a focused beam with a clean cutoff, and upgrading the H11 low beam to LED takes full advantage of that optic. An LED bulb lights up at full power the instant you turn the key, produces a consistent 6000K white color temperature, and runs significantly cooler than halogen. The compact driver module tucks neatly behind the housing, and the entire job takes under 20 minutes per side.
HID xenon kits offer an alternative for 300 owners chasing maximum throw distance on dark highways. The ballast-driven arc tube generates a concentrated beam that reaches farther down the road than any LED or halogen bulb. Installation involves mounting a ballast near each headlight housing, bringing the total install time to roughly 40 minutes for both sides.
All HID Nation kits come with free shipping and a lifetime warranty, making the decision to upgrade the 300's headlights straightforward and risk-free.
Frequently Asked Questions
What headlight bulb size does a 2021 Chrysler 300 use?
The 2021 Chrysler 300 uses H11 bulbs for the low beam and 9005 bulbs for the high beam. The fog lights use H11 bulbs. Halogen projectors are standard on the Touring trim, while the 300S features factory LED headlights.
Can I upgrade my 2021 Chrysler 300 to LED headlights?
Yes. 2021 Chrysler 300 LED headlights are available as plug-and-play conversion kits that replace the factory H11 halogen low beam bulb directly. No rewiring or housing modifications are needed. The LED produces a brighter, whiter beam and lasts significantly longer than the original halogen bulb.
How do you replace the headlight bulbs on a 2021 Chrysler 300?
Access the headlight assembly from behind by opening the hood. Turn the H11 low beam bulb socket counterclockwise to release it, unplug the connector, and remove the old bulb. Insert the replacement LED or halogen bulb, lock the socket back into the housing, and reconnect the wiring. The 9005 high beam socket is accessed the same way on the adjacent port. Plan on about 15 minutes per side.
Does the 2021 Chrysler 300 need a CANBUS decoder for LED bulbs?
The 2021 Chrysler 300 uses a CANBUS-based electrical system that monitors headlight wattage. Because LED bulbs draw less power than halogen, they may trigger a bulb-out warning on the dashboard. A CANBUS-compatible LED kit or an inline decoder prevents this issue and ensures flicker-free operation.
Is the 2021 Chrysler 300 still being made?
The Chrysler 300 continued production into the 2023 model year before being discontinued. As the car approaches collectible status among HEMI-powered sedan enthusiasts, many owners are investing in long-lasting LED headlight upgrades to reduce maintenance and keep the car looking sharp for years to come.
