Got questions?

FREQUENTLY ASKED QUESTIONS

Quick answers to common questions about fitment, installation, and product use.

What is the benefit of Warm White (3000K-4000K) over Cool White (6000K)?
Warm White provides a soothing, high-end OEM ambiance reminiscent of modern luxury European saloons. It illuminates interior controls, maps, and upholstery clearly without creating the harsh, clinical glare or eye strain associated with cool white light, making it significantly more comfortable for nighttime passengers and long road trips.
How do I measure my factory festoon bulb to order the correct size?
Gently unclip your light lens, remove the factory bulb from the spring terminal prongs, and measure its total length from tip to tip with a ruler or calliper in millimeters. Standard automotive festoon sizes are 31mm, 36mm, 38/39mm, and 41mm/42mm.
Why does my car use different festoon sizes in different locations?
Vehicle manufacturers use different housing sizes throughout the cabin to match specific reflector contours. For example, a Volkswagen Vento or Skoda Rapid uses a 41mm festoon bulb for the main front roof dome, but 36mm festoon bulbs for the rear passenger reading lights. Always measure the specific bulb location you intend to replace.
Can I fit a slightly longer or shorter festoon bulb into my housing?
Most vehicle festoon light sockets feature flexible spring-loaded metal prongs that can easily accommodate 1–2 mm of variation. If the bulb feels slightly loose or snug, simply tweak the prongs inward or outward for a secure, rattle-free fit.
Are these bulbs polarity-sensitive, and will they cause ghost glowing?
No. These bulbs feature non-polarity (bi-polar) circuitry, so they light up immediately regardless of insertion direction. Furthermore, integrated Canbus shunt circuitry absorbs minute residual currents, completely preventing faint 'ghost glowing' after cabin lights are switched off.
Will these LED bulbs trigger bulb-out error warnings on my dashboard?
These festoon LEDs are equipped with built-in Canbus load-balancing resistors designed to maintain proper electrical resistance, preventing false bulb-out warnings on European, Japanese, American, and Indian vehicle diagnostic networks.

Description

Canbus Error-Free C5W C10W Festoon LED Interior Bulbs (Warm White, Pair)

Create a refined, relaxing OEM-grade cabin atmosphere with Warm White (3000K – 4000K) Canbus Error-Free Festoon LED Bulbs. Specifically engineered for car owners who prefer the warm, comforting ambiance found in premium luxury vehicles over clinical, overly harsh cool white illumination, these bulbs provide superior lumen efficiency and crystal-clear interior visibility without eye strain.

Fitment & Measurement Guide (Please Read Before Ordering)
  • Measure Existing Bulb Tip-to-Tip: Festoon bulbs share a similar double-ended design but come in 4 distinct lengths (31mm, 36mm, 38/39mm, and 41mm/42mm). Please measure your factory bulb length with a ruler or vernier calliper before placing an order.
  • Different Sizes in the Same Car: A single vehicle often uses multiple festoon sizes in different locations (e.g., 41mm in the main front roof dome and 36mm in the rear reading light or boot).
  • Reference Guide Disclaimer: The compatibility list below is provided for guidance and assistance only. Because automakers vary bulb sizes across trim levels and model years, physical measurement is the only 100% guarantee of a perfect fit.
  • Free Fitment Help: Unsure which size your car needs? Message Durvient support with a quick photo of your light housing or removed bulb for immediate confirmation.

Key Features & Benefits

  • Warm White (3000K – 4000K) Luxury Ambiance: Produces a rich, soothing golden-white hue that eliminates dingy yellow halogen darkness while avoiding cold, sterile blue glare. Ideal for night driving comfort and premium cabin warmth.
  • Extruded Aviation Aluminum Heatsink: Heavy-duty grooved aluminum backing rapidly draws heat away from the SMD LEDs, preventing thermal degradation and ensuring long-lasting performance inside enclosed roof lenses.
  • Built-In Canbus Error Cancellation: Integrated intelligent load resistors eliminate dashboard bulb-out warning indicators on modern vehicle electronics and prevent residual ghost glowing when lights are switched off.
  • Non-Polarity Plug & Play: Reversible bi-polar circuit design allows instantaneous operation regardless of socket insertion orientation—no trial-and-error flipping required.
  • Machined Conical End Caps: Precision-formed pointed end caps lock tightly into OEM spring-clip terminal prongs, resisting road shock and vibration.

Installation Tip

If the new LED bulb feels slightly loose or tight in the housing, gently adjust the vehicle's spring metal contact prongs inward or outward with a finger or small screwdriver to achieve a firm, vibration-proof electrical contact.
