5000K WHITE
Clean Modern Appearance Produces a crisp white light for compatible applications where a white W21/5W light source is required.
PROJECTOR LENS
Forward Light Projection The forward optical lens complements the side-mounted LEDs and helps distribute light from the end of the bulb.
Modern Vehicle Compatibility
CANBUS Ready
Integrated CANBUS-ready electronics are designed to improve compatibility with vehicle bulb-monitoring systems and help reduce warning messages commonly associated with low-current LED replacements.
CANBUS compatibility varies by vehicle. These bulbs are designed to help reduce bulb-out warnings, but vehicle monitoring systems differ between manufacturers and models. Some applications may still require an additional resistor, decoder or other corrective component.
Engineered Construction
Designed For Reliable LED Performance
The LED chips, integrated driver electronics, metal housing and forward optical lens are combined into a compact direct-fit bulb format for compatible W21/5W applications.

Watch the HIDS-DIRECT automotive LED bulb range demonstration, showing a selection of our LED replacement bulbs side by side together with a live illumination test. The product on this page is the White 580 / W21/5W / 7443 7×3030 SMD CANBUS-ready version.
About This Video This demonstration covers the wider HIDS-DIRECT automotive LED range, so other bulb fittings and LED designs may also appear in the video. Always refer to the specifications on this page when ordering this particular 580 / W21/5W / 7443 product.
Fitment Guidance
7443 / W21/5W Is Not The Same As 7440 / W21W
The two bulb formats can look similar, but they perform different electrical functions. This product is designed for 580 / W21/5W / 7443 dual-intensity applications. Always confirm the bulb fitted to your vehicle before ordering.
White LED Upgrade
Crisp White Light & Fast LED Response
LED technology provides immediate illumination when energised and uses less electrical power than a conventional incandescent bulb. The 5000K white output gives compatible applications a clean, modern appearance.
Supplied As A Pair
Two Matching White LED Bulbs
The price is for one matching pair containing two White 5000K 580 / W21/5W / 7443 LED bulbs.
✓ W21/5W / 7443 Dual-intensity T20 / W3x16q bulb format. This is the fitting covered by this listing.
✕ W21W / 7440 Single-intensity bulb. Although 7440 and 7443 can appear similar, they perform different electrical functions and should not automatically be considered interchangeable.
Always check before ordering: compare the existing bulb reference, base, electrical function and required light colour with this product.
CANBUS Ready – Not Universally Error-Free The integrated electronics are designed to reduce LED bulb-out warnings on compatible vehicles. Vehicle monitoring systems vary, however, and some applications may still require an additional resistor, decoder or other corrective component.
They are commonly used references for the same dual-intensity automotive wedge bulb format using a T20 / W3x16q base.
What is the difference between 7443 and 7440?
7443 / W21/5W is a dual-intensity bulb. 7440 / W21W is a single-intensity bulb. Similar appearance does not mean the bulbs are electrically interchangeable.
What colour are these LED bulbs?
This listing is for the White version, producing approximately 5000K crisp white light.
Are these 7443 LED bulbs CANBUS error free?
They include CANBUS-ready electronics designed to reduce bulb-out warnings, but compatibility varies between vehicles and some applications may still require additional resistance or decoding.
Are these suitable for 24V vehicles?
The bulbs are designed for compatible 12V–24V DC vehicle electrical systems.
How many bulbs are supplied?
The price is for one pair containing two White LED bulbs.
What warranty is supplied?
