i need to get fog lamps and highbeams to turn on at the same time in my new 2004 dodge ram 2500 diesel.

 

Depending on where you live, you could get a ticket for that. In Michigan, it's illegal to have more than four lamps lit at a time. Each high beam light counts as two. Therefore, it's ok to have your low beams and your fogs lit at the same time, but you can't have your brights and your fogs lit at the same time: six lamps.

 

That doesn't make a whole lot of since, because you can add Driving lights & according to what you just said then yo will still have 6 lights on at the same time

 

That's right. If you have driving lights AND your high beams on, you are technically illegal. I'm not saying everybody gets written, but it is not legal.

 

Genosgarage.com should have a product your looking for expensive though. It's called a Brite Box. It might work. I would like to have it myself but it's too $$$$$

If you jump the ground contact from the fog relay to the ground contact on the parking light relay, your fogs will go on with the parking lights . Do a search on fogs, you should find the pin location & pin numbers. I did it on mine

 

I can make my fogs go on with the parking lights and my truck is pretty much bone stock. I have not jumped anything to anything, it just works.

 

Why does each beam count as 2? It's just a different fillament in the single bulb, right? When you switch to high beams, the low fillament goes off, so you're still only running 2 bulbs there, right? Add in the fogs and you still have 4 lights burning as far as I can see....

 

I know that it's just one filament on highs, but the highbeams count as two lamps, probably because they are high beams.
