GTR Lighting 50W 3ohm Gold Style Load Resistor (2 resistors), for Custom Installation. When installing LED turn signal bulbs to replace your factory blinker bulbs, you will have a "fast flash" or "hyper flash" 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 HID xenon lighting in some vehicles it will not work properly because the vehicle uses a CANBUS monitoring system. It sees the HID 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 HID 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. If you are experiencing "bulb out errors" "Warning Cancellers" "Fast Blinking" or "Hyper flashing" with your LED turn signals or HID kit. Then look no further. This resistor kit will come with everything you will need for a professional install made easy. Along with the load resistors, you will also receive T-Taps, for easy splicing, and self-tapping screws, for easy mounting. WARNING! Resistors get hot! This is completely normal so Its very important to mount them to something metal behind the headlights with the provided screws, not zip ties. This will ensure that the resistor does not come loose, and it will also help dissipate a lot of the heat. The resistors get so hot they can melt some light plastic and short wires. Keep them away from all wiring and heat-sensitive materials!
