Have any of you done the high-beam all headlights on mod? 4hi/6hi/8hi

[texas1]

I have a 2002 Tahoe LT, 228,000 miles.

Ideally I want all lights on when I turn on the high beams(daytime running, fog, low and high beam) to turn on and looking through Youtube there are several videos showing how to do it. Do you have any experience with modding your headlights to have more than the high beams come on? I don't like how the low beams go off while the high beams are on which is a lack of valuable light when you need to see the dark road.


Here is an example video:

I want to do a mod yet concerned about blowing fuses or part of the electrical system. Thank you.

There is a module that amazon sells for 20 bucks that will get you the 6hi. I would go that route before I start splicing wires.

I see it says 2003-2007, will that work on a 2002 Tahoe?

Also I see this thread from 2010 talking about the 4hi mod: https://www.tahoeyukonforum.com/threads/the-super-easy-4-hi-mod-for-00-02-vehicles.8742/

Will read through that, it may have the answer for 6hi or 8hi. Thanks.

I didn't realize your suv was a 2002, I do not believe its compatible with the 2000- 2002s.

I've seen answers for this question for your year model, but i did not bookmark any of them as all my vehicles are 2003+. I suggest searching this forum, and a couple other Chevy/GMC forums and/or Facebook groups. Good luck, in any case.

I looked at this potential option, as it seemed like a simple conversion. The fuse box in my 07 Denali just does not look anywhere near the same as this circuit board for a direct layover, so there are some compatibility inconsistencies, even within the model years that it is supposed to work with. I even called Fleece Performance to see if they could confirm compatibility with my specific truck, and they could not. Too bad, as I was really excited about this potential option.

You can just add relays to do it. If you don’t want to piece together your own setup, I think Painless sells a kit for the low beams. The same concept will be used on fogs. For 99-02, you can also just add a ground jumper Wire off the yellow wire of the low beam harness to achieve the 4 on hi mod. The lows essentially loose their ground when switched to high on these trucks.

I think @Rocket Man did this mod to his 02 Denali. Pretty sure he had used resistors--at first. I've read Fleece sells the proper module to do an 00-02.

EDIT--I've read it was this one, but now I'm not so sure.

So, did you ever try any of the headlight mods? I did the 4 hi by grounding out the negative on the low beams. Super simple and cheap. I've been running them that way for a while with no issues.

Hey gang, brand new to this forum. Been driving a 03 Chevy Duramax for the last 300,000 miles. Just picked up an 03 Yukon XL Denali. I'm brand new to the Yukon (weeks) and brand new to this forum. However, I tackled this very issue with the Chevy. My solution was quite inelegant: I used diodes in the fuse box to jump from the high beam circuit to the low and fog circuits. Draw wasn't an issue, I'm running all LEDs. I'm a firefighter by trade, so "elegant" isn't in my toolbox. This has been working for the last 100,000 miles or so... Maybe it will be useful here? It's on my list of things to do with the Yukon, I just haven't had it long enough yet...

Yep there’s write ups in the 00-06 tech section.

Thanks for the write-up. But I used this and love it: Fleece Performance Engineering -GM-ALO-37 Gm All Lights On (2003-2007 Classic)

Ive done it.

Ive also heard this works. Take the black ground wire from your low beam bulbs to ground (on the frame) is what I believe works for 4-Hi. Not 6-Hi, not fog lights. Seems like this must bypass a relay that opens the low beam circuit when high beams are on.

Would be great to let us all know how this works out.

Ive done it. View attachment 407068

Looks great.

 

[S33k3r]

Looks good! If you are ever interested in a meetup, I'm in Dallas -- but we travel to Norman about once per year (My wife sings in an Irish band).
