anybody use them? Experiences? Brands you would recommend or stay away from?

Now you have my interest.

Do they stay attached better than the magnetic ones?

I forsee a box of dropped lights coming to a boat ramp near you!

Are these attached to the trailer permanently? Or harbor freight magnetic plus duct tape style?

"You've got a bad ground."

That's always the first thing I look at with trailer light problems, no exceptions. That being said, there are a plethora of other issues that can arise with trailer light wiring and the situation is exponentially aggravated when you're in and out of salt/brackish water frequently, whether you wash down thoroughly religiously or not. Even supposedly well-sealed, LED units give problems eventually.

I use my boat a lot, not a weekend warrior. In fact, I avoid weekends on the water completely three months of the year. I've been fighting this battle for fifty years and I'm sick of it, utility trailers, horse trailers, quad trailers and especially boat trailers. Just seems if there's a quality sending unit to plug into the flat-four outlet on the truck and lighting units that can be easily and securely installed, removed as necessary, it would make my life just a little bit better. I'm wondering if anyone is familiar with such a setup.

I don't see how it would make anything better, but see how it would greatly complicate things. The lights will still need power, so do they have individual batteries? There will also need to be an antenna and circuitry to work the right light bulb (tail running lights, stop light, turn signal).

From what I've been able to learn they run on individual, internal, rechargeable batteries with several hours running time. The matter of circuitry in the sending unit and lighting units is kind of a simple thing to do in this day and age. I don't think the antenna requirements are real demanding for components twenty some odd feet apart. Think about your cell phone and all the other stuff that operates wirelessly.

I know the stuff is out there, I'm just wondering if anyone here has had any experience with it and if there are brands to be recommended or avoided.

Without wires how would you recharge the batteries?

There are lots of small electrical/electronic devices that can be recharged wirelessly these days...many cell phones, watches, etc. Maybe they have a little recharging port like a lot of other devices have.

They're pretty much useless to me. The one's I've seen can last 8 hours (optomistic) then need a 2-3 hr recharge. That gets me to the mountains but I can't get home with no lights unless I hook them to solar or a generator. If you run with daytime lights, you're limited to 8 hrs of driving before you have to recharge. That's a killer for RVers. What's so hard about hard wired lights, anyway?
