Forgive me for my lack of electrical knowledge - looking for some advice.

I am converting my dirt bike to be street legal (have to add lights, turn signals, and a horn).

Currently, the bike has a headlight and tail light that turn on when the bike is running. The bike itself does not have a battery. I think its the stator that supplies the lights with power.

I purchased a Tusk enduro lighting kit. https://www.rockymountainatvmc.com/p...o-Lighting-Kit

The kit runs off its own rechargeable battery and does not have to be spliced into the bikes original wiring.

My question: Would it be possible to wire the lighting kit into say, the bikes original brake light, as opposed to having it run off the rechargeable battery?

My thought process is that I could somehow unplug the wires from the existing tail light (which will be replaced by the tusk tail light), and use the wires from the original tail light to connect to where one would supposedly connect the battery pack to the aftermarket tusk lighting kit.

does this make any sense?

Simple answer is yes. The light is a light and it doesn't care where it gets the electrons necessary to illuminate its filament. What is likely very specific to the Tusk kit is the amp draw of the lights that come with it. If the factory lights draw too many amps the Tusk kit may not be able to keep up with the demand and the battery will drain too quickly.

Not knowing what kind of bike you are working with, is there room on the current coil plate to add a charging coil and circuit next to the lighting coil? If the engine is shared with a street legal bike somewhere else in the manufacturer's line-up then this should be a simple bolt on. If not then you might need to get creative.

What about a title? Converting an OHV title to a street title isn't as easy as just popping down to the DMV in a lot of states or else we would still see awesome modern 2-stroke engined bikes out on the road like god and nature intended us to ride.

Luckily in my county, all you need to satisfy the DMV is have head/brake light, turn signals, horn, and DOT tires. Go to the police station and have a vin verification, and you can get a title. It's actually relatively easy here. I plated my kdx220 and ktm250 but sold them both to get the drz. My two stroke days are over

The bike is a 2001 DRz400 so yes, there is a street legal version. However the street legal version has a battery. I'll have to look for some drz forums to see how other people have added lights. Thanks for the reply!

I know that some more powerful systems will require your stator to be upgraded.

you aren't required to have the lights on, when the engine isn't running?
pretty sure that is a requirement here, for converting a dirt bike over.
it has to be able to power the light for so many minutes, with the engine off. so it has to have a battery.

also as state above, you will want to make sure the stator can handle it, it will likely need to be upgraded. at which point, its probably just easier to mount the battery.

Ah geez yeah then this should be a simple job.
Forgot about the stator, again if you can get a full wiring setup from a wrecker yard DRZ400 you'll be miles ahead of trying to wire in an aftermarket setup. Get the battery, there are tons of low weight options rather than a normal lead-acid battery.
