Bluesky MISC PIL-LI-1156B Blue LED 1156 BA15S Replacement Bulb

The Bluesky MISC PIL-LI-1156B is a blue LED replacement bulb designed to fit standard 1156 (BA15S) single-contact bayonet sockets. This direct-plug-in upgrade replaces traditional incandescent 1156 bulbs with energy-efficient LED technology, delivering a vibrant blue light output for a custom, distinctive appearance.

The 1156 bulb type features a BA15S single-contact bayonet base — a single-function socket commonly found in brake lights, tail lights, turn signals, reverse lights, and parking lights across a wide range of automotive, motorcycle, marine, and RV applications. The blue LED color makes this bulb popular for accent lighting, interior dome lights, and decorative exterior applications where a colored light is desired.

Key Features:

• Blue LED output for custom styling and accent lighting applications
• BA15S single-contact bayonet base — direct plug-and-play replacement for 1156 sockets
• Energy efficient — draws significantly less power than equivalent incandescent bulbs
• Longer service life than standard incandescent bulbs, reducing replacement frequency
• Instant-on illumination with no warm-up period
• Low heat output compared to traditional incandescent bulbs
• Compatible with standard 12V automotive electrical systems

Cross-reference bulb numbers compatible with the 1156 socket include: 1003, 1073, 1093, 1129, 1141, 1159, 1295, 1459, 1619, 1651, 1680, 3497, 5007, 5008, 7506, and 7527. Note: This is a single-contact bulb (1156). If your application requires a dual-function bulb (running light and brake light), the 1157 dual-contact type is required instead.
