Both the 7440 & 7443 are often considered interchangeable due to their similar naming schemes and uses. However, the different types of turn signal bulbs make them more suited for different applications.
Your vehicle uses them in completely different locations. 7443 bulbs are mostly found in front turn signal lights, while 7440 bulbs are used for turn signal lights at the rear.
Perhaps the greatest difference between 7443 and 7440 is that 7443 bulbs use two filaments, while 7440 uses a single filament.

7440 VS 7443 | Are They Interchangeable?
Having tested a number of options for both bulbs, we have determined that 7443 bulbs can be used in 7440 sockets but not the other way around due to the different shapes and sizes.
In other words, if your car requires a 7440 bulb, it would be better to use a 7443 bulb with some slightly modified wires and connections. Turn signals that blink enhance visibility, performance, and safety, as other drivers can easily see them.
Use Cases Of 7440 & 7443 Bulbs
These two bulbs serve completely different purposes when it comes to their uses. The 7440 bulbs are meant for rear turn signals, while the 7443 bulbs are meant for front turn signals.
Some sedans can also have 7440 bulbs for reversing lights and turn signals. Some front parking lights can also use 7443 bulbs.

If you have a 7440 light fixture and are looking for new bulbs, then you should get bulb 7443. The extra contacts on the side of the 7 443 bulbs contact nothing when installed in a 7440 socket, so make sure to order this particular bulb if you need to replace your old ones.
Even if your existing bulbs are still good, it’s always a good idea to change them out every few years in case of an emergency; with newer models like the 7443 available, there is no reason not to do so.
Be aware that changing your bulbs can be expensive – but it will save you money down the road since newer models last longer than older ones and don’t require as much maintenance (especially if they’re using less energy).

This difference affects how they are installed, so if you’re considering upgrading your bulb, consult an expert first. If you own a vehicle that uses lighted taillights (like most Americans), chances are you will want to get some 7440s.
Finally, it’s important to note that although 921 and 7440 bulbs have the same watts, they may look different due to their bases – be sure to compare them before purchasing.
