Headlight mod help

[dstephens1962]

hello all,
I am trying to find a wright up for the hi/lo mod. I would like my low beams to stay on when my hi beams are on. If anyone has any info or a wright up this it would be greatly appreciated.

I don't about that mod but there is one where you can make the fogs stay on with the highs

The high and low are the same bulb so they are always on?? at least 05-07 are

I have seen the fog light mod. Yes they are the same bulb but they have filaments in them.

its one bulb so what does it matter? i dont think the light output would be much more. get recons with 2 seperate bulbs then you can make them both stay on

Found this on another site with a simple google search
THIS IS NOT MY MOD USE IT AT YOUR OWN RISK

here is the readers digest version

1.-Connect ground to body (relay circut 85)

2.-Splice switch or trigger wire (12v) from high beams wire (relay circut 86)

3.-Splice accessory circut to the low beams wire (relay circut 87)

4.-Connect Power from battery to 30AMP inline fuse to relay, (relay circut 30)

5.-Turn headlights on. Your your low beams should now stay on with your high beams!




this will get both to come on when you flip the high beams on...but not kick on the highs when in low beam mode...
Keep in mind however this WILL shorten the lifespan of the bulbs due to heat and possibly damage the housing depending on the housing/bulbs being used.


I tried this setup and the light output was decent, but I was concerned with the heat, I ended up going with the relays to boost the current to the lights, but instead of doing the high/low mod, went with the 90/110w hella bulbs

Anyone have any luck with this mod?

There is a unit called a Bright Box that will do this for you.

Ok Thank you. I did see something about that somewhere.

What I done on my 03. I had the "Bright Box" on my 05 till it crapped out. Havent done the simple relay mod to it yet.

On your normal high beams, your low part shuts off. With the mod, the lows stay on..

Try this with your factory setup. When dark out, look at low beams. Then pull back and hold the "flash to pass" both lows and highs are on. Now compare with factory high beams. You should see the difference.

The "Bright Box" also kept fogs on with high beams.
