this is just my opinion, but I think the better option for 47-53 is to just buy the replacement taillights with LED. I say this because there is a tag light on the left taillight that relies on the park light bulb shining through the white lens, if you use LED they are usually red and dont point down much, so you wont have good tag illumination.
I have used these
