Keep High-beams on with Low Beams ?

Ok so I saw this DIY here but I cant ask anything because the thread is close LOL

Can anyone explain a lil bit more in english this [email protected]

You will need a relay for this. A 5 pin 30/40 amp relay will work just fine. Here is the wiring.
Pin 86-ground
Pin 85-High beam turn on
Pin 30-out put Low beams
Pin 87-Constant 12 volt source
Pin 87a-input low beams


Just a lil briefe and I will do this today

Please and Thank you.

You mean you want your low beam to stay on when you apply high beam. This can be done the way that is mentioned but you do realize that both filaments in the Cobalts case are in the same bulb not sure your bulb can handle the extra heat for very long. This is more a mod for cars with seperate bulb like the G6 for instance or Malibu.

Aftermarket headlamps have the seperate bulbs. I've been meaning to do this, just never got around to it.

Yes that's what I meant, And not problem with the bulb I believe, I have dual halo projectors in my car So low beams is one bulb (8K HID) and high beam is a separate bulb (10k HID) ...Do I explain myself?

Well that's easy then, ground one side of the relay apply the High beam voltage to the positive side of the coil of the 12V relay.This will actuate the relay then wire B+ to one side of relay contact and the other relay contact to the positive on side of the low beam,
.

Even easier would be to just diode the high beam to low beam.

This would be the best you would be using all existing relays and fuses.

[/COLOR]You need a diode because you don't want your high beams to come on when low beams are selected.
