Dual Headlights With Write Up

[Code Blue]

i was thinking of doing this and just decided on getting hids.. the output is ALOT brighter

[jeremyolson84]

clearer pictures would help. but good overall.

[STi2LGT]

I did this tonight, it took me a little over an hour to complete the wiring and soldering. It came out great. I couldn't get a 1 ohm 25watt resistor locally so I took some 1ohm 10watt resistors and wired them in series and parallel to bump my wattage and keep my resistance the same.

[49erRider]

Hate to kinda bring it back from the dead but is anyone making these anymore?

greAt thread

something i wanted to try for ages....

[berzerkus]

FYI i've had this mod for 2 seasons, put on 9k and haven't had any issues other than I had to re-wrap my resistor because of heat. Still recommend it.

[dirtyredface]

I was going to try and do this wiring it up should be no problem, but I was wondering where you put the relay and resistors once wired up?

-- Edit: that was a stupid question I just looked at the bike and there is tons of space easy to Velcro down too

[JoeZ]

Can someone use RadioShack.com and post part numbers for this? Anxious to do the mod, but not sure which parts through them can be substituted to work...

[r_o_b_b_y]

when you do this mod,
do both lights come on on low beam as well as full beam or do you still get the single light when running on low beam?

[endleesss]

Question, on stock setup low Beam on 100% and High Beam on at 40% power right?
Does this mod make the high beam on 100% all the time? I would like to make both on 100% all the time. Thanks.

if you want your high beam on 100% all the time, you don't need to do anything except flip the switch... :all_cohol

ok i got it. i've been messing around with trying different sorts of wires.

[MalteseSteeze]

Do the KP Hybrid mod! I was between the two as well, dual h4's is way better, and modding the h4 bulbs to fit is as easy as cutting out a valentines day card

[cal_look_zero]

Bringing this back from the dead, but a local stereo shop went under and I bought a bunch of relays and resistors, so if anyone is still wanting these made up, I'll be making kits up with guides to tap-splice everything in. PM me if interested.

[cal_look_zero]

I have 4 of these made, 2 of them sold already. I have a limitless supply on materials and have no issues with making one here or there. I improved on the original design a little bit IMO and will sell these for $35 shipped. PM me for details.

[aoc007]

cal_look_zero:

Sounds interesting, can you pm me some general information on how they are designed? I want dual headlights but with the highbeam switch still working and want to make sure that it will not mess up any of the stock wiring in the long term. Thanks

[travr6]

so is this still the best thing going?

I absolutely hate the single low beam headlight set up and this will be the very first mod I do.

Great write up.

Great write up.

HIDs are the best way to go (www.jdmlighting.com)

But for the lowest cost, yes it is the best way to go. I'm still making them for people here and there. PM me if you're interested in either HIDs or the dual beam relay.

Low Beam


High Beam


Great mod! Also wired up the front turn signals to operate as running lights as well.. however they ended up melting because the housings couldn't handle the power dissipation. I bought new turn signals of the same kind and will put a resistor in-line with the running light rail to lower the power.. hopefully they won't melt again!

[Tribal06RR]

So much better than everyone telling me my light is out. Nice Job man.

that is one of my pet peeves esp. when LEOs do it

has this mod affected anyones regulator or any charging components?

[SixHunnit]

oh forgot, Nice write up~!

[travr6]

Nice write up. I fail to understand why some of the manufacturers do this single headlight thing when I have yet to meet a single person that likes it.

I guess now is the time for me to do it.

[slab42]

I like the single headlight. There you go, you 'met' someone that likes it! lol

[Tim600RR]

I have a question on this.

Could you just wire the low beam and high beam bulb wires (positives) together with the resistor in place, and then still leave the original connection for the high beam positive wire?

My thoughts behind this are that when you are on low beam, the current will travel through the resistor to the positive side of the high beam bulb and be at reduced power, but when you hit the high beam switch, the current will take the path of least resistance and travel through the original positive high beam bulb wire thus powering the bulb at full power.

You would only need the resistor and wouldn't need to worry about a relay.

Thoughts?

[slab42]

In theory yes, but you will be drawing twice as much current on the low beam wire when you have your high beam switch off. Not the best idea in the world. You will pop fuses/over heat the wires easier.

[Tim600RR]

Isn't that what your doing with this mod anyway? From the drawing it looks like the high beam bulb is always powered by the low beam wire.

If I knew the resistance of each bulb I could do the calculation to see how much of an increase in amperage we would see. Judging from people saying they have had this mod for a long time with no problems, I would assume it's not very much.

[BenTheRighteous]

Tim, did you go ahead with your version of the mod?

I think, in theory, you're right.

For the low beam case, the high beam wire wouldn't be powered, so you'd get some current going from the low beam wire, through the resistor, to the high beam.

For the high beam case, both wires would be powered, so you wouldn't get very much current going through the resistor at all, and it would be less strain on the low beam wire.

That's a clever observation and I bet it would work. I'm curious if you've gone ahead with it.

[Tim600RR]

I plan to do it once I get the resistor. I ordered a couple off Amazon and they are taking a while to get here.
I'll post up my findings after I try it out.

[slab42]

You are correct. I was thinking this was a different thread about the same thing. Read this one for the drawing I made up and some more info on this:
