i HATE TRAILER LIGHTING............

[Ryan_V]

what I have going on now is I noticed that when I turn the running lights, signal, or brake on.....the same filament in the bulb is lighting. is that an issue from the original wiring from the factory??? looks like I'll be shelling out some money for someone to redo this thing for me I'm done messing with it, gonna rip it all out and start from scratch and have it done right!!

9 times out of 10, anything goofy is ground related. Be patient & good luck.

Ryan MNice is telling you the truth.

[boatfixer]

Yup, when another filiment tries to light up, its usually means it's trying to use that as a ground.

Last time I had a trailerlighting issue it was the GM connection on the back of my truck and not the trailer. I found that out after I replaced all of the wiring on the trialer. But yes most of the time it is ground realted.

I hate grounding problems!!!! Pain in the butt to trouble shoot.

Ryan, also, if you re wire, use the old wires to pull the new ones through the channels, works very well.

[JimBuck]

All very good answers. As MNice suggested, it's usually a grounding problem. I also recommend if your going to redo the wiring to put LED's on if don't have any already. Well worth the investment. Try looking through auction sites for a deal.

I had the same issue as toughguy did. This was after I replaced all of the wiring. Hitchn'Post figured it out for me and replaced that connector deal. Since then just some bulbs went out.

I feel for ya - I've been there and it ain't purdy.

i know what your going threw. keeping the wires all right on trailer is like a never ending task! i get em all fixed up to they work and then someone borrows it and they rip the end off or something stupid. im just going to lock it up and no ones going to use it but ME

then your one of the few. lol everyone that barrows our trailers cant seem to figure it out that the plug ends dont last long flapping on the ground?

That's cause Airjer is a car nerd and knows his stuff. Since I went to LED last year I haven't had a problem yet. Thanks to Air's post on how to do it.
