Driving home in traffic, I looked at my reflection in the tailgate in front of me. 2 lights. Hm, should be 4. Flip the switch off for the fog lights, dark. S**T. Turn lights on/off with the dash switch (thinking maybe I had only turned on the parks by accident), no change.
The way my truck is set up:
- Stock headlights, hi/low, totally unchanged. Even have the crappy OEM sealed beam lights!
- OEM foglight lamps from a TJ, wired to a Hella relay. Relay takes power from switched ignition lead, so on anytime key is on. Have kill switch on dash to bypass and turn off if desired.
- Also have set of Hella 550 (square) lights, with relay, mounted on bumper and wired to high beam feed. Also with bypass switch on dash, but with switch on they will fire when switching to high beams (yes, I know...six forward firing lamps is "illegal"...but it scares the hell outta the deer and the guy who just cut me off).
Now for the fun part. I left the high beams off in traffic so I didn't melt anyone's mirrors, LOL, and drove home with just the fogs (and with the little blocker cup removed, had plenty of light!). I get to my street, turn off the switch for the Hellas, turn off the switch for the fogs. Dark again. Pull the factory stalk for highbeams, they work. OK, not two dead bulbs. Toggle back to low beams while reaching for the switch for the fogs, and .....THE HEADLIGHTS WORK???? WTF????? Toggle back and forth over and over again, no problems ever again even after I got home and sat in the driveway, blinding the dogs off and on by toggling back and forth.
Switch my 2 kill switches back on (fogs and Hellas), no problems with any of the lights.
The lights have been installed this way for about 2 years, no problems until tonight. Is there "a" relay that controls the low beams that's easy to get to? Or do I need to hunt for mouse-chow somewhere in the wiring?
I just noticed for the second time today, that when I drive with my headlights on for an extended period, say 30 minutes, the switch gets warm and the lights go out. I can turn them off and back on and they work. I think mine's in the switch. Maybe yours is too.
I only have fogs wired to a seperate toggle switch. Not to the headlights at all.

The only part of the Hellas that goes to the headlights is a wire for the relay trigger. The foglights are totally independent, they have the heavy hot wire to the battery, trigger wire to the ignition circuit (I think I used the radio switched power wire since I installed both at the same time) thru the on/off toggle switch.
Just made a beer run (c'mon SNOW!), and the lights worked fine. Rear U-joint not so much (about 1/4" play)...but lights were fine
(I think I used the radio switched power wire since I installed both at the same time) thru the on/off toggle switch.
Flippin that switch don't make the radio buzz or anything? Lucky... All the years of stereo install under my belt, anytime I wanted to be lazy and tap into the radio for switched power I'd get radio noise.
Thing I like about my TJ is there are 2 power adaptors one is constant and the other is switched, I have my phone charger and my GPS hooked up to those direct, makes for an easy/clean install

Running with 4 lights on is no problem. I test all my cars by "driving" behind myself in another car in the driveway first. I used to to concert lighting for a living and believe me, I understand how to focus a light the right way for effectiveness without causing problems for others. My foglights are pointed the way they are supposed to be pointed - DOWN and wide, to light the road under the headlight beams (and under the fog if there is any, go figure!). Sitting in a car in front of my Jeep, the fogs actually appear dimmer than the headlights in the mirror. You know, the way they're supposed to be. The Hellas are pointed high and centered (driving, or pencil beam pattern) because I use them with the high beams - only when there are no other vehicles visible.
That being said...the lights haven't acted up since. Strange. I even had to go to an apartment to fix a burst water pipe (THAT was fun...) and drove home in sleet and freezing rain, no issues at all other than I wish I had some heated wipers.
