Wiring Low Beam To Remain On With High Beam?

Has anyone wired the low beams to remain on with the high beams on their JK? I ask because I will be installing my Speaker 8700's tonight and from curiosity I would like to see if the high beam pattern would be "enhanced" from the low beam being on also. The lights require only 2.5 amps per beam, so amperage is not a major concern. I have a rough diagram below of how I plan to wire the adapter harness. Any feedback would be appreciated!

My Truck Lite LED headlights are wired to run both together with no modifications needed to the wiring harness.

You will never have just low beams from what I figure.

Even with the diode between the high/low connection?

Try it first, momentarily pull back on the stalk will light both hi & low. I think the call it the optical horn.
It's been said if you need light down the road (hi), having light up close (low) will detract from your distance vision.

Good input, much appreciated!

I wouldn't use a diode. A relay would work but the canbus system is very finicky. Although the wires will have no problem with the extra load, the computer may not like it. You could always test it with a diode and if it doesn't work try a relay and use the high beam as the switch

I think if you're wanting more light on the road with just the stock lighting you might look into wiring it so the fog lights stay on when the high beams are activated. I did this years ago with my old Mercury car without too much work. I haven't really studied the wiring diagram on the Jeep.

Does anyone know how to wire the fog lights to stay on with the high beams?

Much harder now because of the CANbus. I have seen threads asking about it, but nobody that has had it work.

I'm also not sure you'll need the low beams wired up like that, I'd wire it normal first and see if they stay on, the Truck-Lites do both high and low when set on high.

I wired my front aux lights to automatically come on with my high beans, they were also independently switched. The only difference from your diagram is I used a second diode to prevent voltage from leaking back. You might try adding a second diode in line on your low beams to prevent voltage from feeding back to the canbus. Both my jeeps were wired like this (2010 and 2013).

Get a flashcal or a flashpaq. You can do it with software.

I think it should work. What about bumper mounting a second set of driving lights on the bumper?
On the funny side, have you ever owned a Mazda 626?
A friend of mine bought it at auction. We nicknamed her "Sparky". The Radio only played Christion music
and the original owner, we joked must have heard from god that there is no way this could
have possibly be wired correcty from the factory. The wiring was a spliced up shorting mess. I am guessing from stereo installation.

Installed my 8700's with the new JWSpeaker capacitor harness. No flicker issues, instead of wiring the lights together I am going to add either a Baja Designs 22" OnX or a pair of ARB Intensity lights. I have installed both this past two weeks but cannot decide...

Fog lights kill your night vision and you are not helping yourself. It brightens up the ground directly in front of your mercury car, making it harder to see farther away. You are deluding yourself.

Find a dark road in the middle of the night and drive it with your low beams on and the fog lights in your Wrangler. As you're driving along, turn on the high beams. If you still have the stock headlights you'll see what I mean. You'll think you accidently turned the headlights completely off.

I agree, nothing kills your night vision more then too much light directly infront of the Jeep. windshield lights and roof lights are even worse for long distance night vision.

I do this and i see a bunch of light right in front of the jeep, right where i do NOT need it.

well my roof lights are aimed quite differently from my fog lights.

Cool... Not many folks have sharp enough beam spotlights on the roof aimed properly to avoid glare on the hood.

I'm rimming jw speakers and the lows stay on when the highs are turned on. No mod needed.

Although in a JK you might just end up wheelin' through a road sign, a ditch and a corn field, I hope you don't do this on your RG.

this is correct, same reason why our stock fogs turn off when the high beams are on

Actually, it's a legal issue. Depending on which state you're in it can be illegal to have both the high beams and fog lights on at the same time. Since the law varies so widely from state to state the engineers made it so they cannot both be on at the same time when they leave the factory.

I personally would rather have them on for better visibility when the high beams are on.
