Just installed a set of new LED tail lights from LED 4 RV. They were easy to put in and made a pretty big difference in brightness. The biggest difference I noticed was the turn signal brightness and response.
You'll notice that the tail light housings have been replaced on the trailer - the originals on the 71 were round. The trailer had some work done on it at Airstream in the late 90's. New tail light housings and the addition of vinyl insert moldings were part of that.

I replaced mine the beginning of the year with that same kit from LEDRV and like you I noticed a huge differents in brightness. The back up lights are very bright. I like them so much I have replaced all the lights, amber and red running lights to leds. The only one I have not done is the light over the lic plate, can't seem to find that one.
