so im currently in the middle of building my headlights and i want to do the demon eye mod but heres my question is there such a way that i can make it so when the actual lights are on the leds for the demon eye go out and come on when no headlights are on like somekind of relay or something?

 

Wire the demon eyes into the parking lights, or stick them on a different toggle switch on the inside of the car.

 

not exactly what i wanted i wanted it to do it automatic like in the day when the cars on it will be demon eye and when the night comes and the lights auto come on the demon eye will auto go off must be something i can do with the drl and use a relay to make this work?

 

easiest way would be with relays use the drl as a "reverse trigger"

 

Do explain this reverse trigger. I'm interested in this for my gauge setup I'm working on

 

yea could you explain this possible for you to make up a diagram for us?

 

sorry that i cant do. i know its possible bc ive seen it done before but how no clue

 

well would it hurt to have the leds on and the hid on at the same time?

 

It shouldn't. The lights should over power the LEDs anyway.

 

Use the DRL circuit as the trigger for your demon eye relay.So during the day your demon eyes will be on and once it gets dark,the drls/demon eys shut off and your hids will turn on

 

as long as the voltage is 12v or less, you could use a suitable microchip that has a "XOR" gate. Tap one input to the lights, and the other input to the power supply, then wire the output of the gate to the demon eyes.

The XOR gate will have a high output when one of the two inputs is high, but when both are high the output will be low.

Not sure if this is the route you want to take but there are some kits that are relatively cheap that you can use to accomplish this with minimal wiring. It may sound kinda complicated, but I assure you its not.

 

right it shouldnt hurt at all but you wont see the leds with the lights on
