I own a 1991 25' Excella and just repaired the taillights wiring for the 5th time and you all probably know how frustrating that can be when you are on a trip. I recently found some wireless tow lights on the www.AirStream.com
web site and thought I would pass the link along to you all. I purchased a set and they are really nice and handy. So if I have problems again on the road all I have to do it plug the transmitter into my trailer wiring plug and attach the lights on the rear of my trailer and I am off again. I think these should be a must for all airstreamers, even if you just carry a set with you, just in case...
Here is the link to the wireless tow lights if you would like to purchase a set..
