H4 Dual Headlight Relay Kit

[Bobby K]

Just installed my Eastern Beaver (Love that name) H4 Dual Headlght Relay Kit on my 05 Rocket.

Don't even think about putting the relays and/or unused old plugs in headlight shells. They don't fit, I tried.
Also. remember the small screwdriver type tool we used to change out the terminals for the GI-PRO, well you will need it again, also a pen and paper.

Step one: Raise gas tank, remove headlights from housings, remove right side plastic headstock cover from frame above radiator.

Step two: Trace headlight wires to connectors under tank, unplug connectors and pull headlight wires from open headlight housing end to remove.

Step three: Remove plastic female headlight plugs from relay wiring harness, using jewelers screwdriver or other tool. Be careful not to stab yourself (I did), and write down where each color wire goes.

Step four: Starting on the right hand side of frame, right behind headstock, run relay headlight plug wires to headlights, short one to right headlight, long one to left headlight. After passing wires through holes in headlight housings, replace wires in headlight plugs. Make sure rubber grommet is still in correct place. Headlights then can be plugged in and replaced.

Step five: Plug male plug on relay harness into one of headlight female plugs (see step two) on bikes wiring harness, under tank.

Step six: Run power wires under tank to battery and attach. Install fuse.

Step seven: Use wire ties to secure wiring, push relays to inside of frame, re-install plastic headstock cover and gas tank.

My headlights were noticeably brighter after installation. Kit is high quality.

Does this mean you loose your parking light? You know the little light. Looks like you have yours taped over. Is that right?

Yes, you do lose the little parking lights. What good are they anyway?

Seriously, you can do a bit of surgery and get them reinstalled if you like. I may do that someday down the road.

Since Bobby's method uses one of the 2 cables to plug into the relay kit, the other cable is available to work with. My plan would be to cut the light from the cable used to connect the relay kit and then splice it in with the other unsused cable. You can cut the small rectangular plug and the light off the unused cable. This leaves you with the plug and 2 lights. You can slice in your own wiring, the yellow is the parking light lead along with the black ground wire, and run it up to the headlight housings. Then plug it into the other unused headlight plug.

That's my thoughts...

Holy crap. Its like looking at the sun! Now all I can see are bright spots. Kit works very well, very happy with it.

Mine are still there, I didn't mess with them at all. They look a bit silly since they are still running on the lower power and are yellowish like the headlights used to be, I'll be unplugging them next time I'm back in there installing the Diamond Star Headlight Modulator.

I just finished installing the headlight modulator .... I left the parking lights in anyway. Don't know why, just did. Maybe I thought I might use them someday.
Anyway .... the modulator is kinda neat, can't wait to try it out on the road. I have a feeling it could entice drivers to "move-over" out of the fast lane as a side effect. I won't complain about that little "problem" if it happens.
The H4 dual light kit actually made the installation easier since I routed most everything outside the headlight buckets when I installed it. Ended up not needing the "dual light adapter kit" at all. Just cut in at the high and low beams coming out of the relays, eeze-peezie.
Let you know how it works out after playing with it awhile.

Wow, you went a completely different direction than I did. I kept everything up around the headlight buckets rather than under the tank. Never thought about that idea, might have been more room to work with under there. I did keep the buckets empty too though, only thing in them now is the plugs themselvs.
I got the "low beam shut off" version and put a "carbon fiber" safety covered toggle on the left side plastic trim cover between the engine and down-tube. With it "off", I can run around with just the parking lights on. I got this version so that the headlights could be left off when I start it in the cold weather, you know how you need all the extra battery juice you can get when it's chilly.
How about those BRIGHT WHITE LIGHTS ?!?! .... Awsome aren't they?

Just a side note: When I first turned my lights on after the install, one of my headlights went out. They were about 4 years old and probably used to the low voltage. So now I have one Xenon bulb and one factory. You can tell the difference but the factory bulb is brighter now than the Xenon bulb was before.

Ok I got my kit from eastern beaver It came with no directions except to look on their website I looked and I am still confused of how to do it I have a modulator already hooked up and needless to say when it comes to wires and all that I am a complete idiot I still cant figure out how I got the modulator working I really butchered that job but at least they work Now to go back into that wiring mess I created is going to be a nightmare any suggestions or help would be appreciated

I ordered the dual with low beam shut off, figgured that option could come in handy one day should the battery get low or I wanna be stealthy.
I sure hope it does brightens up the headlights, riding half blind everytime it gets dark has gotten old (me too ), but even if it doesn't with the Sylvania bright-stars it has now ... I will feel better about running PIAA's or something else later on with more wattage knowing the power draw isn't going to burn out another keyswitch (I very well could have killed the last one myself ).
My only concern is how much room there will be inside the headlight assemblies for the parts.

hellfire would you take and post some pictures of your installation of the H4 KIT PARTICULARLY THE CONNECTIONS FROM THE TWO BLUE CONNECTORS and which wires did you connect them to,
I am T.I when it comes to electrics and pictures will help see where and how
thanks
