so i bought a new headlight and im not sure how to hook this thing up. it is a dual light but not the H4s. i have attached a picture so as you can see there are two wires coming from the back of each light. obviously the stock head light only has three wires. when ever i hook the light up i either get one light on and when i switch to bright it turns off, or both lights are on and when i switch to bright it turns off. i dont know if anyone else does it but would it hurt to just to keep both lights on all the time. any help is appreciated.

Do you want one for low both for high? If so there is a how to on the wiki here.

yes thank you for the help i will try and find a diode tomorrow. ill let you know it works.

If you want one on for low and both for high,

connect one directly to   the +12 input to the high/low switch
connect the other to the high wire from the high/low switch

No diodes required.
