OXILAM 7440 LED Turn Signal Bulbs Amber 2-Pack — 4000LM, CANBUS Error-Free

These OXILAM 7440 amber LED bulbs deliver bright 4000LM turn-signal light with built-in CANBUS load resistor compatibility and long-life heat-dissipating construction (2-pack).

Replace stock halogen blinkers with high-output amber LEDs built for easy plug-and-play installation. Each bulb houses 26 SMD chips and runs at 21W with a warm 2200K amber tint, producing about 600% more visible brightness than many factory bulbs while maintaining a compact T20/7440 form. The integrated driver and aluminum body are engineered to reduce error codes and manage heat so the bulbs operate reliably across 12–24V systems.

How bright are these OXILAM 7440 LED turn signals?

The bulbs rate at approximately 4000 lumens per pair (about 4000LM total per bulb in spec sheet) and use 26 3020 SMD LEDs to boost visibility. Bright amber light improves signal noticeability by other road users without changing your vehicle’s appearance.

• 26 x 3020 SMD LEDs per bulb for concentrated output
• 21W power draw per bulb with energy-saving LED efficiency
• 2200K amber color optimized for turn-signal recognition
• Approximately 600% brighter than many halogen equivalents

Will these bulbs trigger CANBUS errors or hyper-flashing?

OXILAM built a CANBUS-friendly driver into each bulb to minimize error codes and false warnings on most modern vehicles. While compatible with many CK/SRCK and standard sockets, some sensitive models (certain Jeep, Chrysler, Chevrolet, GMC, Dodge, Ram, and Volkswagen trims) may still require an external resistor when using multiple LED pairs.

• Integrated CANBUS driver tuned to reduce error messages
• Compatible with many vehicle computer systems out of the box
• Free external load resistors available on request for sensitive vehicles
• Recommendation: check vehicle manual or original bulb part number for fitment

How does the bulb handle heat and longevity?

The housing uses aircraft-grade aluminum and a textured (bump) surface to increase surface area for better heat dissipation. Combined with wide-voltage constant-current electronics, this design helps the bulbs reach a long operational life of up to 60,000 hours under normal use.

• Aircraft-grade aluminum housing for fast heat transfer
• Unique bump texture expands cooling area without extra bulk
• Wide voltage (12–24V) and constant current for stable performance
• Estimated life rating up to 60,000 hours

Are these bulbs a direct replacement for my vehicle’s 7440/T20 turn signals?

These OXILAM units are designed to directly replace 7440, T20, 7440NA, 7441, W21W, WY21W and 992 bulbs in turn-signal sockets. Always verify the original bulb part number or consult your owner’s manual to confirm correct fitment before ordering.

• Form factors covered: 7440, T20, 7441, W21W, WY21W, 992
• Single-function design — intended only for turn-signal use
• Check socket variations across trims and model years
• If unsure, contact seller with vehicle details for fit confirmation

Who is this for? These bulbs suit drivers who want a brighter, longer-lasting amber turn signal without modifying the vehicle’s wiring. They’re ideal for enthusiasts upgrading visibility, fleet managers seeking lower maintenance, and owners of cars or trucks desiring a plug-and-play LED upgrade — provided you confirm fitment for sensitive models that may need an added resistor.
