 Subject: Dual Headlights

I've got an '07 and I want to streetfighter it. I've searched pretty extensively on this forum and the internet in general for more information on dual headlight kits on the Ninja 250. I've found a lot of people and threads adding dual headlight sets, but not a lot of explicit details about the wiring. If I've missed a thread that explicitly talks about this (not just the linked schematics on the wiki), please let me know!

The primary two options I see are:
1) Dominator Dual Headlight Kits
2) Headlights from other sport bikes (old FZR, GSXR, Buell, ZX7, etc.)

It seems as though the Dominator kit is pretty easy, and everything is included to just plug into the Ninja harness and you're on your way. I also like that these lights act as one light, as I am not a huge fan of one light on for low beam and both on for high beam (personal preference).

The other way is to take stock headlights from other bikes, but I have no idea what this entails with the electronics.
Do you need a relay?
Where do you get a harness or do you have to fabricate one (and how do you do that)?
What's the power of the stock H4 bulb and what wattage/style bulbs are appropriate?
Can this easily be wired to act as one bulb, so both bulbs have low and high beams using the stock lightswitch?
From those of you who have done either mod, were you pleased with the results and was it difficult?

Sorry for the exhaustive questions but if anyone can help, that would be awesome!
A guide describing the process might be perfect on the wiki (but I'm biased).

There is very little enthusiasm for streetfighters among Ninja 250 riders. I've tried Smile And if you're looking for a step by step guide, you're kind of missing the point of streetfightering. DIY is part of the process. But I'll try to point out a couple things, and you should be able to do it OK.

Just be aware that 2 x 60w lights on brings the electrical load to close to the maximum for the bike. Keep an eye on how your battery is charging, perhaps by installing a voltmeter.

Stock H4 is 60w high and 55w low.

Bikes that have one light for low and one for high actually give better light, as the reflectors are designed for each light. But you can't tell that to the people who think it looks bad.

The H4 has a simple connection. There are only 3 wires. If you look at the schematic you'll see that High is red, Low is orange, and Ground is black yellow. If you're using a light from another bike, you just need to find the appropriate wires for that light and hook them up. You should use the connector that goes with the new light to connect to the bulb, then crimp connectors and heat shrink tubing to splice into it.

Do you need a relay?

Since the lights are always on, no.

Can this easily be wired to act as one bulb, so both bulbs have low and high beams using the stock lightswitch?

That depends on what the original light was wired to do. If it uses one for high and one for low, you'll blind people if the high is on all the time.

Good luck.
