On a dolly with electric brakes how do you ties the magnetic tail light into the electrical system? Are the fuses sufficient to carry the additional voltage/amps?

The only lights required are the tow dolly.

Generally...the tow dolly hooks into the 7-pole connector on the coach.

The wires in the 7-pin...include the 4 normally used for trailer lights...

Plus:

dedicated Brake wire to electric brakes
Power...for charging a breakaway battery
and an Optional lead commonly used for white back-up lights...BUT don't back up a dolly with a car on it.

If you are hooking up an add-on...you could swap out your existing 7-pole connector on the coach for one of the ones that has 7-pin and 4-pin both. Hopkins makes one. Connect the dolly to the 7-pin and lightbar to the 4-pin.

As indicated, you only really need the fender lights that are on the tow dolly.

I prefer however, to also have lights on the rear of my toad if driving at night. I put a ball on the toad, so that I can easily move the dolly around if I have to. I mounted with U-bolts an angle iron on that hitch ball mount, which I can attach a set of magnetic lights at night.

So I spliced another connection into the tow dolly wiring, which gives me an easy connection point if I need it.

Not necessarily true. If the back of the towed extends too far beyond the dolly lights then you could need add'l lights on the back of the vehicle.
Laws of the state you're in will dictate that, not you home state laws.

We purchased the surge brake..... Master Tow.....
model, no need for brake box, and we run the magnetic roof mount lights, they come with a 3 to one plug that hooks up before the trailer lights, we have towed this way for 10,000 miles so far with no problems. Good Luck!!!
