Will 2015 tail lights fit a 2013?
 

Just want to verify before I buy... Will 2015 frs tail lights fit a 2013 frs?

What are the differences between both OEM tails?

Still the exact same car so they should fit.

Due to Hubble's constant whereby the universe is expanding over time the 2015 taillights will be smaller than the fitment for the 2013. However, this is disputable.

it wont fit unless you swap in the 2015 trunk, rear bumper, quarter panels, roof and rear windshield.

Wutttt

My reason for asking is There are different part numbers from 2013 to 2015 tail lights... The 2015 are suppose to be the new ones without the condensation problems.

Yes, they'll fit just fine. If they wouldn't swap, my Valenti's wouldn't have fit my 2015...

Most likely false...maybe a new gasket, at the most

its not always a gasket problem. condensation typically occurs because the vent membrane doesn't permeate enough.

i.e. either someone at toyota/subaru cheaped out on design (unlikely) or the membrane design chosen has a lot of innate variability during manufacturing and as such you'll find some people with condensation on others with no issue.
