I'm trying to hook up my HID kit and it only allows me to have one headlight on. The right bulb works and the left one just flashes. Could anyone help me with this or send me a diagram.

 

You may need to make a plug like this one so the truck reads both sides as having a halogen bulb even though it does not. I am assuming your kit has resistors but not a total of four right?

You can get those bare plugs off ebay and wire them yourself
