Bluesky MISC PIL-LI-7443W LED 7443 White Replacement Bulb

The Bluesky MISC PIL-LI-7443W is a white LED replacement bulb in the industry-standard 7443 (T20) form factor. Designed as a direct plug-and-play upgrade over the stock incandescent 7443 bulb, this LED delivers improved brightness, faster response times, and significantly longer service life compared to traditional halogen or incandescent equivalents.

The 7443 is a dual-contact, dual-function bulb featuring a 16mm wedge base. Its two-intensity design supports a lower-power mode for tail light or parking light operation and a higher-power mode for brake light or turn signal applications — all within a single socket.

Key Features:

• 7443 / T20 / W21/5W wedge base — direct OEM replacement
• White (cool white) light output
• Dual-function: supports both low (tail/parking) and high (brake/signal) intensity modes
• Plug-and-play installation — no modifications required on most vehicles
• LED technology for lower power consumption and extended lifespan versus incandescent
• Compatible with standard 12V automotive electrical systems
• Also cross-references: 7440, 7441, 7444, W21W, W21/5W

Typical applications for the 7443 bulb include tail lights, brake lights, reverse lights, turn signals, daytime running lights (DRL), and side marker lights. The white output of this bulb makes it well-suited for reverse light and DRL positions where clear, bright illumination is desired.
