My customers asked me if 912 and 921 bulbs are the same.

I would like to explain to you as below.

If they are standard filament bulbs, 912 is the different from 921 bulbs.

Although base model of 912 and 921 bulbs are the same, but watts of them is different.

For example, 912 bulbs are 12v 12w and 921 bulbs are 12v 16w.

Recent years, many customers using led instead of filament bulbs, so led 912 and 921 bulbs are the same.

Because all of led 912 and 921 bulbs are all same base and watts.

I will show you 912 and 921 bulbs as below.
