Using a 921 bulb in place of a 194 for license marker? It would definitely melt the lens and can cause damage to the socket as well. Moreover, the light intensity would be greater with a 921 and can bother oncoming traffic. It is not advised to use a 921 in place of a 194. However, when you are a driver who is frequently stopped by the police for having a dim license plate light, it might be worth the switch.

The 921 is used mostly for backup/reverse lights and has a higher light output than the 194. So, if you are looking to upgrade your reverse lights or add some auxiliary lighting, go with the 921.

Are T10 and 921 bulbs the same?

The usage purposes for the 194 and 168 are more limited. 194 bulbs are mostly found in side marker lights, while 168 bulbs are used as backup or license plate lights.

The difference between a 921 and T10 bulb is that a 921 has a PX chip while a T10 does not. The PX chip allows for greater light output and makes the bulb appear brighter. However, this also means that 921 bulbs have a shorter lifespan than T10 bulbs.

So, if you’re looking for a brighter light, go with a 921. But if you want your bulb to last longer, stick with a T10.
