Hello, new here but have been reading that you can't run the fog lights while on highbeam without causing damage to electrical components.
I used a relay harness. The relay is triggered by the high beam which then sends power straight from the battery to the fog light circuit. They are totally isolated from each other.
I'm wondering if I'm asking for trouble by doing this. I've been running my lights like this for about 3 months now and it sure is helpful during the long dark Alaskan winters.
Thanks in advance.

 

Have a write up of how you did it?

 

I just used a relay harness that you'd use for a hid install. The hot wire for the high beams triggers the relay to send power from the battery to the fog light circuit. It seems to be working great but I was unsure if prolonged use would cause any damage. I was hoping someone with knowledge of the electrical system could share their thoughts on this mod.

 

As long as it's not backfeeding through your fog light circuit (and it shouldn't be) I can't see how it could be damaging anything.

 

Would love to do this. Even a simple hand drawn schematic would help. Thanks,

 

I hope that you have extra $$$ for the ticket you get when the local PD sees this and after he gets his sight back after being half blinded by your lights, he writes you a ticket.....

 

Most of us have the courtesy to dim lights well ahead of approaching vehicle getting in range. You can see approaching headlight a long way at night.

 

What about the car pulling out of the side street or the car coming around the tight curve that you don't see right away? Or the person in the lifted truck with the smart phone in his hand with his lights never re-aimed and can't dim them anytime soon ...


Sure, some try to show courtesy, however as much as I used to drive in my previous job in the early mornings, many would never shut off their brights, their extra bright aftermarket "dim" lights were blinding, and some would never shut off their extra bright modified fogs.


A concept to consider, slow down a bit and use the lights as designed. Maybe my 61 year old eyes are not the best, but it is sure hard to see with spots in your eyes because someone could not care less about anyone but themselves with their extreme bright lights.


Rant over....


Flame away.....

 

This ^

I would install a diode for that.

Otherwise, it wont cause an issue as a fuse should blow if a circuit is overloaded before wires or connections overheat.
