OXILAM 7440 LED Turn Signal Bulbs Amber Yellow 2-Pack — 4000LM CANBUS Built-in Resistor

OXILAM 7440 amber LED bulbs are high-output, CANBUS-compatible turn signal replacements that deliver bright 4000 lumens per pair with built-in load resistor circuitry for fewer errors and longer life.

These OXILAM T20 7440/7441 amber yellow bulbs were engineered to replace factory halogens in turn-signal sockets, offering a noticeable increase in visibility while minimizing electrical issues in most vehicles. Each bulb uses 26 advanced SMD chips, a rugged aluminum body for heat control, and an internal driver tuned to reduce hyper-flash and dash warnings. They are sold as a 2-piece kit and are single-function: intended exclusively for turn-signal use.

How bright are these bulbs and what color do they produce?

OXILAM 7440 LEDs emit a powerful amber-yellow output equivalent to approximately 4000 lumens per bulb rating (pack of two cited by manufacturer specs) and a warm 2200K hue designed to match traditional signaling color expectations. The design uses 26 x 3020 SMD chips per bulb to concentrate light toward the lens for clear, noticeable signaling.

• 26 SMD 3020 LED chips per bulb for intense output
• Rated brightness: 4000LM (manufacturer spec)
• Color temperature: 2200K amber yellow for standard signal appearance
• Energy draw: ~21W per bulb, lower than many halogens

Will these trigger CANBUS errors or hyper-flashing on my car?

These bulbs include a built-in load resistor and a CANBUS-tuned driver to decrease the chance of warning lights or rapid flashing on most modern vehicles. However, some sensitive ECU systems—especially on certain Jeep, Chrysler, Chevrolet, GMC, Dodge, Ram, and Volkswagen models—may still require external resistors or additional wiring adjustments.

• Internal CANBUS driver reduces false error codes
• Compatible with CK/SRCK and standard sockets in most cars
• Manufacturer offers free external resistors if specific vehicles need them
• Using pairs or fitting on particularly sensitive models may need extra load support

How durable is the construction and what is the expected lifespan?

The housing is machined from aircraft-grade aluminum and shaped to increase surface area for improved heat dissipation, which helps keep LED junction temperatures low. Combined with a stable constant-current driver and wide voltage tolerance (12–24V), the bulbs are built to last and are rated for long service life under normal operating conditions.

• Aircraft-grade aluminum body for efficient cooling
• Unique bumped surface increases dissipation area
• Wide voltage compatibility (12–24V) and constant current design
• Manufacturer rating up to 60,000 hours under ideal conditions

Which sockets and applications are supported?

These OXILAM lamps are designed to be direct replacements for common turn-signal and blinker sockets such as 7440, T20, 7440NA, 7441, W21W, WY21W, and 992. They are single-function bulbs intended only for turn-signal use and not recommended for DRL or parking light circuits.

• Fits 7440 / T20 / 7441 / W21W / WY21W / 7440NA / 992 socket types
• Single-function: for turn signals only, not DRL or parking lights
• Confirm fitment using the vehicle owner’s manual or part number
• Check variations across trims and model years before installation

Who is this for? Drivers who want a bright amber upgrade to factory turn signals while avoiding common dash errors will appreciate these OXILAM bulbs. They are suited to owners comfortable verifying their vehicle’s socket type and, if necessary, performing a simple wiring modification or accepting a free external resistor for particularly sensitive systems. If you need help confirming compatibility, contact the seller with your vehicle make, model, and year before purchase.
