Technical Specs Of 1157A Bulbs

This miniature light bulb has a diameter of only 1-1/4 inches and a length of 2-3/8 inches. The 1157A has a double contact bayonet (BA15d) base and is used as a turn signal, stop light, or tail light on many modern vehicles. The 1157A bulb has a power rating of 12.8 volts and a wattage of almost 27W. It emits a light output of about 200 lumens.

The 1157A is an improvement on the original 1157 bulb, which was introduced in the 1950s. The 1157A has a higher wattage and produces more light than the older model. The newer bulb also has a longer life expectancy, making it a good choice for modern vehicles. With a brightness of 302 lumens, this bulb may be used as a day running light in some applications.  The color temperature of about 2800K is very close to sunlight, so it may also be used as a backup light.

Finally, the 1157a has a relatively long lifespan. It's not uncommon for this bulb to last for several years, which makes it a good investment for your vehicle. This will help you avoid the hassle and expense of having to replace your bulbs frequently.

What Is The Difference Between 1157 And 1157A Bulbs?

Type A is amber-coated, and Type N is natural glass with no coating. So, these lamps have different appearances. The major difference is in the light output. The A-type has 30% more light output than the N-type. So, it is brighter. If you are looking for a lamp to use as a turn signal or brake light, then the A type is a good choice. 

In other situations, both 1157 and 1157a bulbs may be used in the same way. They may be interchangeable in some applications, but it is always best to check your vehicle’s owner’s manual to be sure. All you have to know is that they both must have similar socket types and electrical specifications.

Are 1156 And 1157 Bulbs Interchangeable?

In fact, they are not. The 1156 lamp has a PGJ13 base, whereas the 1157 one has a BA15d base. So, they are not compatible. 

The 1157A is an improvement on the original 1157 bulb, which was introduced in the 1950s. The 1157A has a higher wattage and produces more light than the older model.
