Coupe tail light bar question

[blackhawksfan18]

Alright so recently I have been getting the "brake light" dash light for my light bar on my trunk. Thinking it was a mistake I checked every time I got the warning. Until just now I got it again only this time the bulb is out. However, one of the bulb sizes is different from the other. What I mean is the 2 brake light bulbs for the trunk piece are different sizes. One is 7443 and another is 3057. Is this how its supposed to be? Why are they different?

7443 should be there.

7443 should be there.

So why would 3057 be there instead? Should I buy a whole new bar? I don't really want to buy two separate bulbs for the same piece.

Buy 2 pack, intstall one, other in glovebox for when another dies. Throw wrong one out.

Forget about plastic thing, unless you didn't mention something.

7440 is reverse lights, 3057 is brake b/c the bulb has to be dual filament

I decided to go outside and mess around with the current bulbs before I went out and bought anything. After screwing around, I just left the 3057 and 7443 in the trunk piece after various tests to see what bulbs are out. Warning light has not come on after starting it once but I'll see how it is tomorrow. Appreciate the help guys!

Sorry, 7443 should be norm
