In stock · ships from Knoxville
The 4157N is a miniature incandescent bulb with an amber glass envelope, typically used in automotive and truck lighting for turn signals, parking lights, side markers, and brake lights.

It replaces standard 4157 or 3157 sockets where an amber color is required by vehicle regulations. These bulbs have a wedge base and operate on 12-volt systems, providing a warm amber glow when energized. Over time, the filament burns out or the bulb dims, so it's replaced when the signal flashes rapidly or the lamp remains dark.
