Dual filament BAY15d replacement bulb.
In automotive and trailer applications, this bulb is used for tail (3 CP)/brake-signal (32 CP) lights, with one or both filaments illuminated.

The 1157 bulb is the most commonly used. It is somewhat brighter and lasts longer than the similar 1034, in spite of the fact that they both have the same 32 candlepower light output rating.
The 1157 also has a higher wattage brake/turn signal filament.

The 1034 bulb was commonly used in in older, pre-early 1970s vehicles.
