Yes,  they replaced the 194's. They only work one way. You have to make sure not to mix up the + side of the bulb with the - . They wont work if they are backwards. I tried to look up when I installed them, I couldn't find any record of it. I havent driven my car hardly at all since the bash, so I thought the battery was low but charging it didn't make them come back on.

Well, at least you know the fix. 
 

 
Yeah ----- Make sure the battery is fully charged.

Really looking good now that they all match

I'm very impressed with the LED's. They make such a difference with brightness and the current draw on them is like a fraction of a conventional bulb.

I always wonder about the LED bulb swaps and such. How many of you actually drive your Mustang at night? I did for many years while winter hung around. To work in the dark, to home in the dark.
I run with my dash lights off so I can see better on the unlit roads. In the city I just flow with the traffic and don't need to see the dash. 

I drive my car quite often and even at night and sometimes in the rain. This is what made me upgrade to things like LED bulbs.

I bought a set of LED tail lights.
