When installing: LED bulbs to replace your factory blinker bulbs, you will have a "fast flash" or "hyperflash" problem. This means the vehicle will think you have a light bulb burnt out and, as an indicator to you, will flash quicker than normal. Installing these resistors will fool your vehicle into thinking it has a light bulb in good condition installed and will blink normally. Simply wire the resistor between the ground wire and the blinking positive wire. When installing LED xenon lighting in some vehicles it will not work properly because the vehicle uses a CANBUS monitoring system. It sees the LED ballast instead of a regular halogen bulb and thinks there is a problem. Some cars or trucks will give a light-out warning indicator light on the dash, others will simply not supply headlight voltage, or flicker the headlight voltage. Installing this universal resistor kit with your LED kit will fool your vehicle into thinking it has a normally functioning halogen headlight in place. Simply wire the resistor between the ground wire and positive wire for the headlight bulb.

WARNING!: The resistors get hot! It is very important to mount them to something metal behind the headlights with screws, not zip ties. The resistors get so hot they can melt some light plastic and short wires. Keep them away from all wiring and heat sensitive materials!
