How to Troubleshoot Trailer Lights that are not Working

[@flossfly1783]

Thank you for helping all the people who have a trailer light issue. Am about to tackle a faulty trailer and have some solid info. Thank you!! The internet is a mixed blessing but stuff like this is gold.

[@homesforbeginners]

Thank you so much for the kind words, happy to help!

[@MrAvh1]

Gave me some additional ideas on how to troubleshoot and repair the lighting system! Thanks! (soldering, shrink tubing, plastic casing.)

[@nutnfancy]

Excellent: clearly filmed, succinctly narrated, well done!

[@homesforbeginners]

Thank you!

[@montellwilliams811]

@@homesforbeginners say , I replaced the wire & now the fuse continues to blow 🤔

[@RiverRat734]

You’re the man solved my problem- bad ground at the wiring to brake light connection

[@thomasjensen3226]

kick ass dude! TY! having it clearly explained and layed out really takes the worry out of the equation. subscribed!

Hi there, thanks for the great video. I really appreciated that you had video transcribed for clarification.

[@homesforbeginners]

Thank you so much for the kind words and feedback!

This was super helpfull. Thank you, it sorted my problem out.

[@beardedbiker2647]

Glad I found this, I have a small trailer that apparently was wired from 7 way to 4way flat. It had single bullet connectors with the extra wires soldered to the outside of the connectors, Unfortunately when I unwrapped everything only the ground was still connected and I’m trying to find my running lights with only a blue, red, and black wires left to connect.

This video was exactly what i needed.good explanation.thanks for sharing!!! Deer hunter 101...

[@jackherbic6048]

I like your channel you do the how to genre perfectly

[@homesforbeginners]

I appreciate that, thank you!

[@rememberme9818]

Thanks, it is helpful, but my trailer turn signals and break lights works when I use signal or break, but they should turn on as soon I turn headlight on that is the problem I am having, if any help I will appreciate.

Great video! Thanks!

You're welcome!

You've done a great job thank you for that !!!

[@russellmcdaniel5652]

Great tutorial

[@homesforbeginners]

Thank you!

[@coltcele8420]

This was a great video. I bought a test light, and I learned here I learned here I had the ground on the wrong lead on the truck side. My brake/hazards are fine, getting power. The lead for them at the truck side isn't getting power. Any thoughts why this is? Thanks in advance!

[@stevesaviano1419]

Well done, great info, BUT... I believe my issue originates at the back of my Class A RV. My 7 way cord works properly when plugged into the back of my friend’s pick-up, connecting to my car. But I get absolutely nothing when I run it from my RV to my car. Any ideas or suggestions on where the problem is, and how to repair it?

[@Humble_Lyfe]

Would this also work with a test connection tool if it has a positive and and negative. Since mine has two different probe. Not like yours. If so. How?

[@djtall3090]

Great job on the video! thanks

[@rolandmetayer7210]

Very well done ! Thank you. Cheers from Canada.

[@mattsmith6828]

This is very informative! When it comes to wiring trailer lights though, I cut the "Y" harness, clean through, and install Deutsch (DT) connectors at every light. This way, when I go to replace a burned out light, I only have to crimp one side of the wire and I don't have to worry about replacing (and re-routing) a whole new wire. Even if I have to replace lights frequently, because of this connector, the length of my original wire stays the same length, as I'm only replacing the short amount of wire leading to the light itself. I admit, it is more expensive, but on the positive, you don't have to spend $75 and 4 hours in your garage when something goes wrong. Lastly, if you buy Hopkins trailer brake lights, replace those disgusting, mushroom cap, cheap steel bolts with stainless steel, hex head bolts (1/4"-20 - 1.25" length). Can we PLEASE put an end to the "guuud enuuff" people!?!?!?!

Nice thank you

You're very welcome!

[@matthewmorrison7030]

I have an old tent trailer that has black, green, yellow. It also has a blue/red wire alongside. There is also a black/red wire coming out that was screwed into the trailer (potential ground). I cannot get the 4 way connector to work. I've tried almost every color combination. Any ideas?

[@homesforbeginners]

Have you used a multimeter to do continuity tests from the plug to each light socket? The wiring could possibly have a break somewhere or it could simply be a bad ground if nothing is working. If you do find a break, sometimes it's just best to replace the whole system, it can be easer than chasing a problem. I have a video for that over on my other channel, kzbin.info/www/bejne/ep2rpaeOadOegK8

[@lubabalomakeleni5567]

Hi, thanks for the video and I must say that it's very informative. However, I have one question can you please tell me as to what is the red wire from the light for?

[@izaiahrocha1729]

The red wire from the test light is the ground

[@russellburton8228]

All my lights are working, brake, hazard and L & R turn signals, but the running lights don’t work. I’ve checked the wiring and the fuses and have run a cat and mouse tester on that one wire and it runs complete up to the fuse box. This is a 2003 Ford Ranger. Any help would be appreciated

[@Kirk8269]

Thank you 🙏🏻

[@lindamuvic8110]

Thanks, first thing I did was pull my white wire out, so my connection would reach my truck.

[@karenlee1093]

❤thanx😅

[@behzadanwar9396]

My left signal work but when I on right signal, the left and right both start blinking please advise solution sir

[@atb1040]

My trailer light is solid and not blinking when I use the turn signal

[@joehead1294]

When doing diagnostics on trailer wiring, only hook up the electrical. Putting the trailer on the hitch ball may make a bad ground issue hard to find as it will try to ground through the hitch which is what you don't want.

[@SOFTCORE_FISHING]

My break lights work but not my running lights. What could that be?

[@cowboyjack570]

Did you check the fuse in your tow vehicle? Usually a short blows the fuse

[@SOFTCORE_FISHING]

@@cowboyjack570 yessir. It looks fine.

[@cowboyjack570]

Now you need to test where you lose the power. If you have power to the plug then start tracing where you lose power. Probably a broken wire. Good luck Dustin! I have a love/ hate with tracing wires. Lol

[@betto2017]

what about if lights does not work it all? where do you check?

[@homesforbeginners]

You need to go back further onto the vehicle then. Could be the module for the trailer connector on the vehicle, could be a fuse. This will vary depending on how it's hooked up.

[@marypetersonma6661]

I have a 4 flat , white red green and black on the truck going into a 7 plug and a 7 plug ,on the trailer with with yellow brown green and white on trailer how do i connect it

[@russellburton8228]

All lights are good on the truck side as well as the running lights

[@valdo-_-killer6294]

What if all lights work except for one fender light thay blinks every now & them

[@homesforbeginners]

That could be a bad ground specially for that light, a bad power wire, or corroded light socket.

[@garthtimmins2852]

Trailer lights are not very complicated, and yet I am always surprised by how many people there are who are towing trailers with non-working lights.

[@wmhill906]

great,,,,,,,

[@flierbill]

Dang it, I should've watched this first, test light, bulbs, tail lights. Cost a lot.

[@topshelfredneck4253]

So my lights worked fine then it sat for 3 months now none worked. I checked there getting power all the way so I didn't think it possible all the bulbs going bad at once

[@milesbbop9563]

crazy how fixing things still cost just as much money. tools and a good personal place to work. might as well pay somebody.

[@louisvillalba7695]

At least you’re not paying for labor

[@dantemagz6672]

That’s why no one wants to pay mechanics a fair labour cost, parts are expensive now, just the way it is.

[@leonapelletier9659]

Not when u do it more than once lmao maybe 1 time but over time u save way more doing it yourself

[@Shonuff42080]

Do you throw the tools out when your done???😅😅
