Excellent! Simple but thorough.

Great videos much appreciated you have turned a mystery into something logical

[@KnettersPracticalOutdoors]

Glad to help

Practical video again! Have to check it out every time I get notified and never disappointed. Regards

[@KnettersPracticalOutdoors]

Thanks for watching, KPO.

[@mikesmith9297]

Good info. I apply a dab of dielectric grease to all electrical contacts (base of bulbs, harness connectors, etc.) and check them every spring and fall. Works great at preventing corrosion.

[@KnettersPracticalOutdoors]

Yes, that helps, KPO.

[@hodagtrapper4167]

Great information. Will come in handy for a lot of outdoor enthusiast!

[@KnettersPracticalOutdoors]

Thanks, KPO.

[@boatman222345]

Great video! Couple of tips: Drexel tool with wire brush attached is great for cleaning electric contacts. If you don't have any sandpaper handy grab one of your wife's throw away pasteboard fingernail files.

[@KnettersPracticalOutdoors]

Cool thanks

Nice Job! You are very knowledgeable and well articulated in explaining. I know all this stuff, I'm going to watch your other video on meter knowledge. That's what I want to know. New subscriber, Capt. Vic

Welcome aboard Capt. Vic. Thanks for the comment, KPO.

Love your videos! Very informative and explanatory! But here’s a situation for you that you may have covered and I missed: My trailer lights flicker ONLY when my trailer coupling is fully weighted down onto the hitch ball. When I lift up on the trailer and relieve some of the weight, the lights stay on steady! This one kinda stumped me. Maybe someone has a suggestion or a fix? I’m using a 4 pin trailer light wiring harness hooked to the tail lights of my pickup, as it did not come with a tow package. I only recently began having these issues when I replaced the trailer coupling

[@KnettersPracticalOutdoors]

Your white wire should have a good electrical connection to your trailer frame and the truck frame when plugged in even with the coupler off the hitch. If weight on the hitch changes things, my guess is the trailer isn't grounded properly. Also see kzbin.info/www/bejne/gpK4m2qQfteqd80 KPO.

I am here try to never miss your videos

Thanks as always Richard, KPO.

I just bought a brand new trailer(5x8) from lowes. Running lights and break lights work fine. Turn signals flash fast. Ive moved the ground wire(white wire) to a different location. I sanded the paint off before mounting it. Still having the issue. The bulbs are good. I noticed when I take the fixture off of the trailer the the turn signal blinks like normal once its mounted again it blinks fast again. What could be causing this. I have the flat 4 way plug. I have had a slightly larger trailer hooked up to my vehicle and the turn signals work like they should. Any help would be appreciated

[@KnettersPracticalOutdoors]

Wow, that is a good one! I haven't seen this exact problem before. Only think that comes to mind is some newer cars can't handle the extra current a trailer can add to the circuits. I know it stinks to do this to a new trailer, but I might try going with LED fixtures. Let me know if you figure it out. I am puzzled.

[@HadHellkinsasmysnsince1989]

@@KnettersPracticalOutdoors Im pulling this trailer with a 2011 Ford Flex. It's like I have to "un-ground" the current fixtures for them to flash properly. I'll look at some LED fixtures and Ill let you know if it fixes the issue or not.

[@Balsero-qb9gv]

Very informative video sir. I'm facing a challenge right now, maybe you could help please. I just put a brand new lights kit on my trailer. New LEDs lights, new wires and new connector to the car From the car I see coming out 6 wires (black, white, brown, green, yellow and red) that were connected to an old broken trailer light power module that I took off, but when I connect those wires to my trailer wires nothing happens. Do I need a trailer light power module for sure or can I just connect those wires from the car straight to the trailer? I can tell that I have power up to the tail light on my car because everything works well in the car. Thanks so much for all your help, is very appreciated.

[@KnettersPracticalOutdoors]

Some vehicles need the power module because some vehicles have separate brake and blinker circuits. While the trailer uses one circuit to do both. The module converts to match the trailer. You would have to find out if your make and model vehicle requires the module or not. As for the wiring, hopefully your module either plugs in or has a diagram. KPO.

[@bcdwalleye6242]

Trailer lights are like beaver. They never stop giving you problems.

[@KnettersPracticalOutdoors]

Correct, KPO.

[@andyparstino7280]

I have LED fixtures and I have one break light that won’t work everything else works 😬😬 frustrating any ideas ???

[@arieljones4595]

Me too!!!! Dammit!

[@arieljones4595]

I figured it out today. It wasn't the trailer at all. The trailer circuits are individually fused in the truck. The left turn/stop fuse was popped. For that's worth.

[@KnettersPracticalOutdoors]

Does the blinker work on that side? If it does the brake should work also as they are the same wire. If the blinker works on that side, you may have a problem on the vehicle side of things. Does that brake light work on the vehicle? KPO.

[@andyparstino7280]

Knetters Practical Outdoors yes blinkers work and they light up when i turn lights on but just braking. Prob just replace everything this winter

[@Lifeinthe906]

Ground wire ?? What a concept lol. Dad always told me don't worry about that it will ground thru the ball! Needless to say most time his trailer lights did not work too well.

[@KnettersPracticalOutdoors]

Well Mike, your dad's not wrong. But if the coupler is a little rusty inside or the ball is a little rusty, your lights will flicker in and out as you go down the road, KPO.

[@Lifeinthe906]

@@KnettersPracticalOutdoors You got it Dave my dad is always the guy with the flickering taillights!!!!

[@BS.-.-]

I have seen these type of trailer lights that the pressure of the bulb pushing on the metal piece also was keeping the wire touching the metal piece. Do your self a favor if you have a broken light or one that isnt working, corroded or your constantly having issue with it..change both to LED. There under $40 for the set.

[@KnettersPracticalOutdoors]

I agree, KPO.

[@dwheeler016]

Thanks. I might use a small wire brush

[@KnettersPracticalOutdoors]

Yes, that will work, KPO.
