New headlight wiring? Pics of new setup

[Jaytibba]

I'm planning on setting this up to the 1993 ninja 250, making it a street fighter. Already got the headlights directionals and mirrors. Next will be installing the vapor tech. Any ideas how to do the wiring on this thing?

Stock wires


Wires from new lights

They are both the same in the back. That blue wire is white on the inside.
So it's green and white on both. With an extra brown on one (high beam switch?). The one with the brown wore also has the wires lead up front to a second bulb

New lights plus screen and directionals I added


Words on lights 12v h3 55w


This is the back of the lights open. One of them I'm guessing the high beam light the wires look split and the wires lead to a single bulb up front


I really want this to work out. I have done so much to the bike and this wiring is the last bit it needs before I can start riding it. I'm not good with diagrams and stuff so and "help for dummies" would be huge.


I have the fork clamps and all hardware. Plus electrical supplies pretty much just need helping figuring out connecting which wires to the right ones.

H3 bulbs don't have low/high filaments. They're just on or off if they have power or not. You give them power on the white wire in the middle of the bulb, and they ground through the housing (connected to the green wire). You'll have to rely on the instructions or use your meter to figure out which color wires run to where. It looks like one of the bulbs might be connected to that blue wire?



The intent with that setup is probably to aim one as a low beam and one as a high beam. Power the low beam from the the bike's red/yellow wire and the high beam from red/black. Black/yellow is the bike's common ground wire.

Keep in mind that the stock wiring is designed to support a single 55/60W H4 bulb filament at a time. You don't want to run both of those 55W lights through the stock wiring at the same time (in case you wanted to keep the low beam on while the high beam was on). You'll need to add a relay for that.

Wow Thank you so much that was a HUGE help. I actually just found this from eBay which has the same lights and tells you what colors do what.


So it looks like
red/yellow to green (low)
Red/black to green (high)
Black/yellow to both brown and white
Blue to nothing? And this will be one on at a time?

Soon further inspection it does seem the white wire in the middle is insulated in white

High beam light


Low beam light


So it seems the wiring picture I found above would be wrong and the ground and power wires are backwards.

Got the same ones on mine but I had my friend do it for me since I am not good with electrical stuff. I can take a look at how he did and get back to you in the morn.

Edit : Nevermind. Guess you got it figured out. lol :P

That would be cool none the less, you can never be too sure when it comes to something you know so little about aha. How do you like it? A pic of it installed would be nice to see

Yes, the green is obviously ground, since it connects to the housing. White and blue are your low and high beams (i.e. light #1 and light #2). That leaves brown, which should be for the little "city light" (which is generally more of a non-US thing) by process of elimination.

That eBay pic is why I never blindly trust internet info. With all the cheap Chinese knockoffs these days, it's quite common for two things to look identical and be wired completely differently. If you can't see both ends of the wire, use your meter and verify what goes where. Blowing a bulb isn't so bad, but destroying your new electronics because you used the colors from an iffy wiring diagram is a major downer.
