M-1157W Lucas Lighting 1157 High Output CANBUS LED Bulbs Switchback White – Pair
Lucas Lighting M-1157W 1157 High Output CANBUS LED Bulbs White – Pair
Upgrade your factory 1157-style reverse and backup lights with the Lucas Lighting M-1157W High Output CANBUS White LED Bulbs.
Designed as a direct replacement for compatible 1157-style halogen bulbs, the M-1157W delivers high-output white LED performance with an instant-on response and optimized LED positioning inside the factory light housing.
The M-1157W is the white version of the Lucas Lighting M-1157 M Series, specifically intended for reverse-light applications. Its dual-mode design uses a lower-output mode for the constant-on function and a higher-output mode for safety functions where applicable.
Lucas Lighting also incorporates its latest CANBUS technology to provide broad vehicle compatibility and help minimize common LED conversion issues such as bulb-out warnings and fast blinking.
Sold as a pair of 2 bulbs.

High-Output White 1157 LED Replacement
The M-1157W replaces compatible 1157-style halogen bulbs with a high-output LED design.
Rather than relying on a large number of low-power LED chips, Lucas Lighting's M-Series uses fewer, higher-power LED chipsets positioned as closely as possible to the original bulb filament location.
This helps optimize the light-source position within the factory housing, allowing the original reflector and lens to work more effectively with the LED replacement.
The result is a modern white 1157 LED replacement designed to provide a brighter, faster-responding alternative to a conventional halogen bulb.
White LED for Reverse and Backup Lights
The M-1157W is the white version of the M-1157 series and is designed for reverse applications.
Common uses include:
- Reverse lights
- Backup lights
- Compatible white-light applications
- Other 1157 applications requiring a white light source
The white LED output provides a clean, modern appearance while the instant-on nature of LED technology provides immediate illumination when the vehicle is placed into reverse.
Always verify the required bulb type and light color for your specific vehicle before ordering.
Optimized LED Light-Source Position
Proper LED positioning is especially important when upgrading factory halogen bulbs.
The M-Series uses fewer but higher-power LED chipsets positioned as closely as possible to the original filament location. This design helps maintain the light-source position the factory housing was originally engineered around.
For the M-1157W, that means you get an LED replacement designed with the factory reflector and housing pattern in mind rather than simply adding LED chips to a traditional bulb body.
Advanced CANBUS Technology
Some vehicles monitor the electrical characteristics of their factory bulbs. Replacing a halogen bulb with a standard LED can sometimes result in bulb-out warnings or other compatibility issues.
Lucas Lighting incorporates its newest CANBUS technology into the M-Series 1157 bulbs.
Lucas states that this technology is designed to provide compatibility with greater than 90% of vehicles without causing bulb-out errors or fast-blinking issues.
Vehicle electrical systems vary, so certain applications may still require additional electrical components.
1157 / BAY15D Cross-Reference Compatibility
The M-1157W is compatible with a broad range of 1157-style and cross-reference bulb numbers, including:
94, 1016, 1034, 1034LL, 1142, 1157, 1157ALL, 1157LL, 1157ST, 1178A, 1196, 2057, 2057A, 2057ALL, 2057LL, 2057ST, 2357A, 2357ALL, 2357LL, 2357NA, 2397, 2397LL, 3496, 3496LL, 7528, 7528L, 7528LL and BAY15D.
Cross-reference numbers indicate bulb-style compatibility and do not guarantee fitment for every vehicle. Always verify the original bulb number and socket configuration before ordering.
Direct Replacement Design
The M-1157W is designed to replace compatible 1157-style bulbs using the existing factory socket.
Its BAY15D-style dual-contact base allows it to work with compatible dual-function 1157 lighting systems without requiring modification to the factory housing.
Installation is straightforward: remove the original compatible bulb and install the Lucas M-1157W LED replacement.

Important Fitment Information
Before ordering, verify that your vehicle uses a compatible 1157 / BAY15D-style bulb and that the application requires a white light source.
The M-1157W is intended specifically for reverse applications. It should not be assumed to be interchangeable with the M-1157R red bulb or M-1157SB switchback bulb simply because they share the M-1157 platform.
Lucas lists numerous cross-reference bulb numbers, but cross-reference compatibility does not guarantee fitment for every vehicle. Verify the original bulb number, base style and physical fitment before ordering.
CANBUS compatibility can also vary depending on the vehicle's electrical system. The M-1157W is designed to minimize common LED conversion issues, but certain vehicles may still require additional components.
