If you need an LED bulb that just WORKS: this is your problem-solver LED! This LED is an exclusive innovation by GTR Lighting.

Constant Current Driver: The Carbide 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.

When installing LED 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.

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 for maximum heat dissipation and increased lifespan. Plug and play bulb replacement for all T15/921 bulb applications.
