The 3157N features natural amber glass that emits amber light without an exterior coating, so it resists fading over time. It is a dual‑filament bulb providing both a bright (stop/turn) and a dim (tail/parking) output. For even lighting and safety, replace both bulbs on the same axle at the same time.
