I can't figure out how to connect my driving lights so they come on with the hi-beams. I have hella 500s, that are now just on a switch. Both wires running to my hi-beams (rid w/ grey stripe, red w/ green stripe) are hot when off and then one dead (red w/ green stripe), one hot, when the lights are on.

I have tried running the ground to the one that goes dead when activated, but that doesn't work. Does anyone have any ideas that I can try?

 

you are probably not going to be able to do it becasue your vehicle uses a ground side switch.... thus it can ultimately be done with an adapter box which is a set of properly hooked up relays and stuff, but not through the regular conventional methods

 

That is very annoying to hear. Thanks for the info.

 

I had my Hella 500s come on with the high beams. I just ran the power lead for the relay, I think it was the green wire, to the high beam wire that was energized when the high beams were on, that way when I turned the Hellas on with the switch they would only come on with the high beams. Also this way the Hellas always went off when I turned off the rig. Never had a problem.

Good luck!

 

He's right in that it can't be done by simply splicing into the line like it can on domestics, but it only takes one relay. My PIAA 520's are wired to come on with my high beams.

Basically, all the relay does is change the negative switched stock system to positive switched for the aux. lamps. When you flip the high beam switch on, it closes the ground for the stock lamps. It also closes the relay, which then turns on the juice to the aux lamps. Spend a couple of quality minutes with a multimeter and it should become apparent to you where the relay needs to go and what it needs to do.

 

So I figured out how to do it. I ran the ground from the relay to the line from the hi-beam that is hot both when the light is on and when it is off. I ran the hot side of the relay (actuator?) to the fuse box and spliced it off the low beam fuse. (I still have the power coming from the battery and going to the lights.)

Now I am not that electrically minded, so I have no idea why this works, but I know that it comes on with my hi-beams and goes off otherwise, so I'm happy.

Thanks to Rob for the help here, letting me know it could be done.

Brian, do you remember which wire that was on the socket. I'm multi-meterless.

 

There are only two, you got a 50/50 shot you pick the right one! Sorry, I don't remember (seems like it was green too). A good multi-meter is an invaluable tool and you should buy one!

 

Hah..well then. I'm on the low beams one now...But there are a total of three wires on the headlight socket. I'll just try the opposing wire.
