AUXITO 31–36mm Festoon LED Bulbs 6500K White 6-Pack — 18×4014 SMD, Aluminum Heat‑Dissipating

If you want a straightforward upgrade from dim halogen festoon bulbs, the AUXITO 6418/3175 six-pack delivers a plug-and-play solution built for brighter, whiter illumination and long life. Each bulb uses 18 4014 SMD chips arranged on a curved board for even light distribution, and the retractable non-polar springs accept both 31mm and 36mm sockets. The bulbs are marketed for a wide range of vehicle interior applications and include thermal-friendly all-aluminum housings to help manage heat during extended use.

How much brighter are these bulbs compared with stock halogen festoon lights?

These AUXITO festoon LEDs use high-density 4014 SMD chips that produce significantly more lumen output than standard halogen festoon bulbs, giving a clearer, whiter 6500K light. The semi-circular chip layout reduces hot spots and spreads light uniformly across the area.

• 18 x 4014 SMD LEDs per bulb for stronger output
• 6500K color temp for crisp daylight-white illumination
• Curved LED board minimizes shadows and hot spots

Will these replace my existing 31mm or 36mm interior bulbs without modification?

Yes. AUXITO festoon bulbs include retractable, non-polar springs on both ends so they fit common 31mm–36mm festoon sockets without adapters. The non-polar design and integrated IC driver mean most vehicles will install as direct replacements with minimal risk of flicker.

• Retractable springs for 31mm–36mm compatibility
• Non-polar connections for easy plug-and-play installation
• Built-in IC driver reduces flicker in 99% of installs

Are these bulbs durable and suitable for long-term use in a vehicle?

The bulbs use an aluminum body with a hollowed design to promote heat dissipation and protect LED longevity. AUXITO rates the bulbs for extended lifespans, and the shock-resistant springs help maintain contact under driving vibration.

• Aluminum housing for improved thermal control
• Shock- and vibration-resistant spring contacts
• Estimated service life up to 50,000 hours under normal conditions

What vehicle locations are these bulbs best suited for?

These festoon LEDs are intended for interior and exterior auxiliary lighting where 31mm–36mm bulbs are used. Typical placements include dome lamps, map lights, door courtesy lights, trunks, glove boxes, and license plate illumination.

• Dome, map, and courtesy lights for brighter cabin lighting
• Trunk and glove box illumination for better visibility
• License plate and parking lights where festoon bulbs are required

Who is this for: drivers and DIYers who want a reliable, brighter replacement for factory festoon halogen bulbs without rewiring or adapters. This six-pack suits people upgrading multiple interior fixtures, restoring dim map or dome lights, or improving license plate and trunk visibility with a clean, daylight-white 6500K tone.
