AUXITO LED Festoon Bulbs 31–36mm 6-Pack White 6500K, 4014 SMD with Aluminium Heat Dissipation

AUXITO DE3175/6418 31mm–36mm LED festoon bulbs are plug-and-play, high-brightness white LEDs designed to replace common interior and license plate halogen bulbs.

These AUXITO 6-pack bulbs use 4014 SMD chipsets arranged on a semi-circular board and fit most 31mm–36mm festoon sockets thanks to retractable, non-polar springs. They deliver crisp 6500K daylight white output, faster turn-on than stock halogens, and an aluminum body engineered for heat dissipation and long life. The following details explain compatibility, light quality, installation, and who benefits most from this upgrade.

How do these bulbs compare to stock halogen festoon lamps?

Compared with standard halogen bulbs, the AUXITO 4014 SMD array produces a stronger, whiter light with instant-on performance and reduced shadowing from the chip board design. Their aluminum construction keeps operating temperatures lower, which preserves brightness and extends service life.

• Brightness: 18x 4014 SMD chips per bulb for higher lumen output than halogen.
• Color temperature: 6500K crisp white for clearer interior illumination and improved visibility.
• Durability: aluminum housing and hollow design for improved heat dissipation.
• Lifetime: rated up to ~50,000 hours under normal conditions.

Will these fit my car’s dome, map, or license plate light?

The bulbs are designed to replace common festoon halogens in 31mm–36mm sockets and are compatible with many OEM part numbers such as DE3175, 6418, 6411 and similar models. Always verify your vehicle’s bulb size in the owner’s manual or remove the existing bulb to confirm length before ordering.

• Fit range: adjustable springs accommodate 31mm to 36mm sockets.
• Cross-compatibility: replaces DE3175, DE3021, 3022, 6418, 6411 and related codes.
• Applications: dome, map, courtesy, trunk, glove box, license plate, vanity lights.
• Polarity: non-polar springs for easy installation in most vehicles.

How difficult is installation and will I get flicker?

Installation is straightforward: remove the old festoon bulb and seat the AUXITO unit into the spring clips. Most vehicles will not experience flicker thanks to the built-in intelligent IC drivers, and the non-polar springs prevent reverse-polarity issues during fitment.

• Type: plug-and-play, no wiring or adapters in most cars.
• Driver: integrated IC reduces flicker on 99% of vehicles.
• Shock resistance: springs designed to withstand vibration and road shock.
• Tip: if flicker occurs, test bulb orientation or consult vehicle compatibility list.

What performance and safety features should I expect?

The LED arrangement and semi-circular chip board aim to produce even light distribution without dark spots, while the rapid turn-on and higher perceived brightness improve interior visibility. The aluminum body and hollow profile help manage heat, maintaining consistent output and protecting electronics.

• Uniform light: semi-circular layout reduces shadowing inside vehicles.
• Fast response: near-instant illumination compared with halogen warm-up.
• Heat control: aluminum housing for better thermal management.
• Longevity: rated life significantly longer than halogen alternatives.

Who is this for? Drivers who want a quick, cost-effective upgrade for interior and exterior festoon lighting will benefit from these AUXITO LED bulbs. Ideal for owners looking to improve cabin visibility, modernize license plate illumination, or replace worn halogen festoon lamps with a longer-lasting, whiter light source. Confirm bulb length and socket type before purchase to ensure fitment.
