LEDYOTRY 7440 Amber LED Turn Signal Bulb Pack of 2 — 4000 lm, CANBUS Compatible with Built-In Resistor

If you need a direct replacement for factory turn-signal bulbs that improves visibility, these LEDYOTRY 7440 amber lamps are engineered as a plug-and-play upgrade. They pair high lumen output and thermal management with an intelligent driver to reduce CANBUS errors on most modern vehicles. Each pack contains two single-filament bulbs designed specifically for turn-signal sockets.

How bright are these LEDYOTRY 7440 bulbs and what makes their light effective?

These bulbs use 36 high-output 3030 LED chips to produce about 26 watts and roughly 4000 lumens per bulb, yielding strong amber illumination visible in varied conditions. The design provides near-360° light distribution so there are no dead zones or uneven patches around the lens.

• 4000 lumens per bulb for strong signaling visibility
• 36 × 3030 LED chips for even light spread
• 360° illumination to avoid dark spots
• Amber color tuned for turn-signal recognition

Will these bulbs cause dashboard CANBUS errors or hyper-flashing?

LEDYOTRY equips each bulb with an upgraded intelligent IC driver and integrated resistor to prevent most CANBUS warnings and reduce hyper-flash on the majority of vehicles. However, a few sensitive systems may still require an additional external load resistor for perfect compatibility.

• Built-in intelligent IC driver for wide compatibility
• Integrated resistor and anti-hyper-flash circuitry
• Compatible with about 99% of vehicle CANBUS systems
• Optional external load resistor may be needed for some cars

How long will the bulbs last and how do they handle heat?

These 7440 lamps combine an aluminum housing with an active cooling system—a turbo fan rated at 12,000 rpm plus layered temperature control—to maintain stable operating temperatures and extend service life. LEDYOTRY rates the lifetime up to around 60,000 hours under typical use when the cooling system functions normally.

• Aluminum housing for efficient heat dissipation
• Turbo fan (12,000 rpm) for active cooling
• Multi-layer temperature control to reduce overheating
• Estimated lifespan up to 60,000 hours

Are these bulbs easy to install and which sockets do they fit?

Installation is straightforward—typically a 5-minute swap—because these are single-filament plug-and-play bulbs designed only for turn signal applications. Confirm your vehicle uses one of the compatible socket types before buying to ensure a proper fit.

• Single-filament design for turn signals only
• Fits 7440, T20, 7440NA, 7441, W21W, WY21W, 992 sockets
• Not intended for daytime running lights or parking lights
• Quick, tool-minimal installation in most vehicles

Who is this for: drivers who want a brighter, more noticeable amber turn signal without extensive wiring changes. These LEDYOTRY 7440 bulbs are best for people replacing worn incandescent blinker bulbs, upgrading visibility at night or in poor weather, and owners of vehicles whose computer systems accept LED replacements without additional modification. If your car is particularly sensitive to LED loads, be prepared to add an inline resistor for flawless operation; LEDYOTRY also provides customer support if issues arise.
