I also have my driving lamps installed, and they "work", but not the way I was hoping...

Like most driving lamp kits, they have their own dashboard-mounted, wired switch. They can currently be turned on or off via this switch, whether I have the low beams on, or the high beams on. It doesn't matter.

This isn't ideal.

Obviously, I'd really prefer that the driving lamps just come on automatically when I activate my high beams, (via the steering wheel-mounted stalk).

Said another way, I want to push the stalk forward to turn on the high beams, and at the same time, have the driving lamps automatically come on. Consequently, when I pull the stalk back to turn on the low beams, I want the driving lamps to turn off automatically. All of this should happen without having to touch the switch for the driving lamps at all.

Does that make sense?


Currently, (having done the foglight mod), I've made a bridge between the orange wire in the fuse panel, to the red/green wire in the fog light relay. This bridge is currently where I've also connected my driving lamp wire.

Can anyone please help me? I cannot fathom that I'm the very first person to hook up driving lamps so that they work with the high beams on a 2002 WRX... Somebody has to have this answer out there in cyberspace!

Help me Obi-Wan, you're my only hope...
You'll need to use a driving light relay. You should locate the relay near your driving lights. That will give you the shortest run from your battery to your driving lights. Be sure to have a fuse in the wire from the battery going to the relay contacts. You'll run two wires from the relay coil back to the dash. One wire will be connected with a vampire clip to the RED wire on your high-beam relay.

The RED wire is the switched ground for your high-beams. So your relay would pick up (turn on) when your headlights were turned on.

Connect the other wire to one side of your driving light switch. Connect the other side of your driving light switch to the GREEN WITH A WHITE STRIPE. This will make sure your driving lights are off when your ignition is off.

I'm not sure where the high-beam relay is located. Plus I'd like for someone to verify my thinking before anyone follows my suggestion.

Also I hope someone can write this up more clearly.

The large Green wire is from your ignition switch which turns on the ignition relay. The G/W wire is controlled by your ignition relay. Connecting to it gives more isolation from the rest of your system. Either should work.

You'll hook your driving lights from the driving light relay contacts to ground.
