This is how you have your trailer's clearance lights turn on when you are parked and disconnected from the tow vehicle. I also posted this elsewhere.

Thanks, now I know how to shut my neighbors lights off easily

gbopp wrote:Okay. Why?No reason. Just for fun. Like when everyone around you strings LED rope lights and you didn't bring any. Also, by the way, this will confirm if your trailer is setup correct for the truck to recharge the battery while towing. Sometimes the converter blows a fuse or pops a breaker and you never know. If you insert the fuse and the clearance lights don't come on, then you may have a problem. I didn't dream this up, it was explained at a recent mfg. rally by a senior maintenance guy.

Been posted here many times. Usually turns into a dsicussion about annoying your neighbors.

gbopp wrote:Okay. Why?They often do this at RV shows to make the campers sparkle a bit more with razzle and dazzle. Manufacturers and dealers will also put an automotive "flasher" in those same two holes on the camper plug to make the running lights flash on and off.The flashing running lights when not hooked up to a tow vehicle has at least one good application - in the event you are on the side of the road, and have to drop the trailer and leave it because of breakdown. The running lights on the camper will flash like 4-way flashers.I learned this little trick many, many years go, and used the flasher on several occasions for 4th of July camping and a couple times to annoy neighbor campers when they insisted on leaving their flood lights on after dark. (and it worked too).Haven't used the "flasher" in several years now, but I still have it in my RV camping goodie repair stuff bag tucked under the bed in the event I get the "mood" again.I have seen on many occasions, RVers having their running lights on with this method while camping. I think folks do it when they first learn this can be done and it's kind of nostalgic for them. After it wears off, they quite doing it. I kind of enjoy seeing campers with their running lights agow, because I know these folks probably just discovered this little trick and are all excited about it. I simply enjoy their joy! It makes camping so much nicer.

What purpose does that serve?

It gives you emergency flashing lights for your trailer if you have to leave it on the side of the highway at night.

Ok. I can see that being a 'real' good idea for a safety feature.

Yes, but a real annoyance in a campground, even just lighting them up, as stated by many before why go camping then have all the bright lights of the trailer.

Selective reading, eh? :R Obviously neither of you before commenting bothered to read what I posted back on Page 2 of this discussion as to how & why I flash all the running lights on my own trailer ........Helps to read what is written. :W

Feel all better now? :R

So your reason why, is the only reason therefore everyone else should stop posting? I didn't quote nor was I responding to your post.

Pick some one else to bash.

"I took it a step further and built my own Trailer Lights Dongle (3 pics) and use it every time I back in from the street on to our driveway to warn other dumb*** drivers what I'm up to. MUCH better flashing ALL the trailer lights, not just the 4-ways, in this situation.

Just buy one that comes already equipped with, "look at me my TT lights up at night".

Stepped out of my MH one night to this, thought the Aliens had landed behind my RV!. :E

Daylight revealed this called an Inferno??
