7440 Signal / Reverse-Light Check
For 7440/W21W sourcing, verify the wedge socket, 12V/24V electrical requirement, emitted color and whether the target position is signal or reverse lighting. Validate fit and electrical behavior on the target lamp before bulk approval.
W21W / 7440 LED Bulb for Automotive B2B Sourcing
W21W / 7440 / T20 LED bulb for automotive signal, reverse-light and wholesale/OEM sourcing. The listed configuration features 15 x 3030 SMD LEDs, 7W power, 12V–24V input and 700LM output, with multiple color/application options shown on this product page. Confirm the exact ordered color, polarity and target socket on the approved sample. See the 7440 LED bulbs wholesale sourcing guide for sample, MOQ, packaging and RFQ planning.
W21W 7440 LED Bulb Technical Features
- LED Configuration: The listed configuration uses 15 × 3030 SMD LEDs. For B2B evaluation, compare LED placement, optical distribution and thermal design on the exact quoted sample before bulk approval.
- Performance Data: Confirm the rated power and lumen output for the exact quoted 7440 configuration; this product record contains conflicting power/output data that should be resolved before bulk approval.
- Voltage & Fitment: Confirm the rated voltage, base dimensions, polarity and target 7440/W21W/T20 application for the exact quoted model.
- Construction & Service Life: Confirm the material and thermal design for the selected model and request model-specific service-life evidence when required.
W21W 7440 LED Bulb Applications & Color Options
- Amber (1800K): Confirm the exact color specification and target signal-light application for the quoted sample.
- Red: Confirm the exact color specification and target brake/tail-light application for the quoted sample.
- White (6000K): Confirm the exact color specification and intended reverse or other permitted application for the quoted sample.

Why Choose 3030 SMD LED Technology?
LED chip configuration and optical performance should be confirmed for the exact quoted model. Where brightness, thermal behavior or durability is part of the buyer’s acceptance criteria, validate the approved sample and request applicable test information.
Note: Some modern vehicles with CAN-BUS systems may require an additional load resistor to prevent hyper-flashing on turn signals. Please check your vehicle’s compatibility. Submit a 7440/W21W wholesale, OEM or private-label RFQ to LEDVEDA.
