Armor Series GTR Lighting 7440/7443 LED Bulbs: The Armor Series of LED bulb is impressively bright, with an unparalleled Black-Chrome style. The white is one of the brightest bulbs we offer, and the other colors are vibrant and impressive. The Armor series look great on and off, so if you're looking for a super bright option that also looks cool, you've found the right option!

Using state of the art: 2835 SMD LED chips to produce unparalleled light output with high-efficiency power usage! The focusing lens on top creates a 165 degree beam pattern output and the decorative metal style of the bulb surrounding is an excellent heat sink. This means we can push these LEDs to the limit without risk of damaging them from heat! Get ready for an amazing bulb that will last a very long time.

Constant Current Driver: The Armor Series of LED bulbs from GTR Lighting are built using a state of the art Constant Current Driver inside the bulb. This allows them to be more reliable when used on vehicles that have voltage fluctuations due to electrical system design or fault. A constant current driver is a device that takes any incoming voltage and smooths it out, regulates it, so a steady stream of voltage/current reaches the LED. This helps the LED bulb last longer than bulbs that don't have this device built in.

GTR Lighting 50 watt 6 ohm Gold Style Resistors:

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!
