DRL Delete

My new Spyder headlights are installed, and working/looking great. My only gripe is that the DRL is still used...

I have the LED bar and the CCFL Halo's wired to the parking light circuit, which is where I want them, but when they're on (all the time), I don't want the bulb in the high beam housing on. Is there a resistor anywhere that I can pull out? Or any other way to disable that without buying the harness from Shark Racing?

In a word . . . NO.

The low voltage sent to the high beam bulb for the DRL is controlled by the BCM. I have read where some knowledgeable computer programmers have hacked the BCM firmware to turn off the DRL feature on other makes. And I believe that on some BMWs the dealer can, and will, turn them off . . . but the Hyundai software does not include this option. If you want them off, spend the $60 and get the harness-- (I think the harness is over priced and I am surprised some other Chinese company has not started offering these at half Shark's price.)

You CAN do some simple jumpering of the parking brake switch and kill the DRLs-- but this will cause the red dash "Brake" light to come on . . . if you do not mind the light--or if you can live with out it by removing the bulb, you would be good to go. Still the harness is just plug-n-play . . .

Basically what rick has said....if you have a Bi-Xenon projector...or a half decent low beam only projector just pull the high beams bulb out, problem solved. Or if you put in a seperate switch to make the car think its ebrake is on, that will work too. But youll obviously have the red symbol lit on your dash all the time

When I suggested removing the bulb, I was referring to the bulb for the red warning light on the dash-- not removing your high beam bulbs. If you jumper, or alter the switch on the parking brake-- the DRLs go OFF. The DRLs are OFF when the parking break is set or when the switch on the parking break is activated, even when the car is in gear and moving. The only problem with this method is that when the DRLs go off that annoying red light on the dash for the parking break goes ON.

just unplug it.
unless you actually use your high beams

but if its that rare occasion you do use them ..plug em back in..unplug when back in the city

you could try and make your own harness?
but for the parts and effort ..bah..just buy from shark

A good reason NOT to mess with the parking brake switch to kill the DRL's is that by forcing the brake warning light to be on all the time, you are compromising your safety and that of your passengers. That light also serves as a warning of brake system failure as it indicates low brake fluid. If it's always stuck on because you shorted the wire, you won't have warning in the event of a serious fluid loss.
I wouldn't do this.

Not just low brake fluid - it also comes on in the event of a failure of the Electronic Brake Force Distribution function in the ABS unit, which could reduce brake effectiveness.
