Yes, you need a brake light!

Here's the link to the whole wiki. The subcategory is "lighting - you blew it."

This one has been helpful too. I think I'll hit up maize for a wiring diagram.

Return to what? The stator?

I have a rectifier regulator. Depending on what the head light looks like when it arrives, I may or may not have to ground it. I'll probably have to ground the tail lights.

That's what I said. Yes your dad is correct. Both the floated ac light coil and the DC that is produced from it (rectification) are not grounded to frame. But is your ac floated?? Do u know what I mean ?

To clarify, the 6v ac ignition coil will be grounded to the frame. Anything coming from the 12v coil will be floated.

Float the AC, no need to run deficated grounds everywhere.

Your Dad is a smart guy.

I finally got all the parts and rewired the whole bike. The headlight is BRIGHT! I love it. The tail light and brake light works as it should. But the lights still flicker even though its dc going to them. I'll probably put a battery in the loop. Any suggestions on the battery? Preferably something small.

.... use an mr16 12v "landscaping" bulb.

There's a thread on here somewhere that discusses it.

This seem like a nice one. I've had two somewhat lesser rated (lumens) wired parallel STRAIGHT to the stator. Dim but stay lit when idle, lights up the road fantastically when running. Been running two summers now non stop. No problems. These MR16 bulbs just seem to love the ragged peaky voltage coming off my ZA50. Internally rectified, choked, smoothed, etc. Have little circuit boards inside. Nice pattern at 35degrees (mine). The above might be better yet at 25d.

I'm know nothing about electronics and lighting. I tried an mr16 on a lark since menards had one on sale for a buck. I was astonished at how well it worked just wired direct. So I got a much better rated pair from Home Depot for six bucks each and wired them parallel. Ran beautifully. Many many hours later, still running like new. Very happy. (edited)

I know almost zero about electrical. I tried an LED sealed beam and small LED tail lights. Light lasted about 2 weeks and died and took that the tail LED.

What do you all mean about "floating" a ground to AC. Don't ground to chassis? Details appreciated.

If there is a non LED headlight bulb that works in the stock light and is better/best, please share a link for me! Appreciate!

By float I mean do not ground to chassis. The plug is getting AC. Everything else grounded to the chassis runs off of AC.

I got a 12v light coil and ran it through a trail tech regulator rectifier before the led lights. LED lights will not run well on AC and will burn out quickly. This is 12v DC coming off the reg rec. Do not ground this circuit to the chassis. Mixing grounding of AC and DC is a bad idea. Simply route the black wires back to the reg rec. So float it. Meaning it is not grounded, but the circuit is complete.

For my tail and brake lights I just got cheap bulbs off amazon that had the same base. The headlight is actually intented for a tractor. I dont have the link anymore but its friggin bright as hell. Do a little searching and you'll see which brand I'm talking about.

In a nutshell. To run led lights, get a 12v light coil. Use a reg rec to convert to DC. Float the circuit.

My rig had worked solid for about a year with no issues.

This is the headlight I used:

This is what I used for the tail light:

So when you guys say float the ground, you are talking about using some sort of additional voltage regulator off a 12v system. I was just asking if there is any LEDs that will work with the stock 6V system that won't fry, and won't cause troubles with the stock electronics.

I don't understand all the bits that need to be changed and added for 12v or if that introduced any additional problem areas. Treats has a 12 volt light coil: https://www.treatland.tv/puch-12-volt-light-coil-2-0-improved-version-p/puch-light-coil.htm

But it is out of stock. Is this a "plug and play" part with a regulator, or does everything that get's connected need to be "floated" as you say (i.e. a positive and negative needs to be run from the coil? but no ground should be attached to the chassis in any other manner?)

Appreciate the patience. I am admittedly ignorant on vehicle wiring topics, but I would like to learn. I had a little Honda 250 motorcycle, and I just replaced all the bulbs with LEDs and everything was cool. I'm taking it that the moped puts out this someone "old fashioned" AC electric at 6volts stock, and this is what gives the LEDs fits. By using the 12 volt coil and running that to a 12 volt regulator, each LED light for the headlamp, and tail lamp can be wired to the regulator. Where it would get complicated is the brake lights, as you need to wire the brake switches into this "floating" part of the system. And you still need to leave the horn and ignition on the 6volt part of the system? So I'm assuming there are two coils in play?

The light I used is a larsen tractor light. If you get the right size it will def fit in the original light housing.
