A couple guys asked about how to do the Bambi Mod (Fogs & Highs on at the same time) and I tried to help with my lame pics. Here is someone who did a much better job.


Landstrom's Foundry Techincal - F-150 Fog Lights

How To Get Better Bambi-Vision With Your 2004-2006 F-150
or how to jumper your fog lights so they stay on with your high beams

If you live in a rural areas you understand the necessity of throwing as much light down the road to light your path and spot any critters in lemming mode that are waiting alongside the road to end it all by casting themselves in front of your cruel tires.

Nowadays there are government laws that require manufactures to turn off OEM fog lights when the high beams are switched on. Annoying since most people turn on their high beams because they want more and not less light. All the more unfortunate since late-model F-150s leave something of a "dark spot" right in front of the vehicle with high beams on that the fog lights would illuminate well.

After hitting five deer, one skunk (that was bad), a porcupine, and whatever else, my contribution toward animal conservation was to convert my fog lights so they stay on with my high beams to help me better see and swerve around the little buggers that dive out in the road.

This is how it is done with 2004-2006 Ford F-150s:

First, disconnect your battery.

Behind the passenger kick panel on your late-model F-150 is your fuse box. Pull the access cover off, locate the relay in the top center and pull it out.

To make your fog lights stay on with the high beams, you need to provide a permanent ground to one of the pins. At your work bench carefully bend over the tab you see in the photo above. Try to be gentle but bend it over so that it nearly folds over on itself and follows the contour of the relay case. Then get a length of wire (I used 20g) and crimp on a female blade and stick it and the attached wire on the relay pin you folded over. When you're done you'll have what you see in the photo above.

Before you push the relay back into the fusebox, use a side-cutter to nibble away or notch the plastic to the right side of the relay socket on the fusebox to gain clearance for the folded over pin. Then pop in your relay and make certain that it is secure.

Now locate the green grounding bolt located below and rearward of the fusebox. You'll want to pull the door kicker panel partially out to gain clearance for more space to work in (that pannel has two clips: pull straight back and the panel will lift out of the way). Route the lose wire coming off of your relay behind the big electrical plug on the rightside (rearward) of the fuse box, cut off the excess wire and crimp on an eyelet. Remove the green grounding bolt and reinstall the bolt with your grounding wire.

Button the two panels you pulled out of the way back up, and then connect your battery. You're done and should feel pretty good about yourself because your fog lights will now stay on with the high beams!
 
so i put mirimoto h13 2stroke 2.0 LEDs in my headlights yesterday and they work great high and low BUT...if i have the low beams on and i turn the fogs on, it automatically flips the high beams on. Nuts. im gonna try this mod later on at work and see if it will help. i called mirimoto and they have never had that happen before


i like how this post is 9 years old haha
 
Lol, we've been here a while.

I've heard of people having issues with LED headlights and the fogs. There isn't enough resistance in the LEDs and that's what causes the high beam issue. Usually you can see the hi-beam light in the dash glowing slightly.

Shoot I'm almost positive i had that happen with my '97 years ago. Having a really hard time remembering. My '97 is Bambi modded using a relay that uses the highs as a trigger to kick the fogs back on and i wanna say that relay was allowing current to flow backwards through it when the fogs were turned on and it would power up the highs.
 
pretty easy fix, took...maybe 5 mins. the lights make a HUGE difference at night. ill get some pics
