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 o+C301ut, 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 "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.

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!

Purchased this kit after researching what options I had. Headlight Revolution not only had the suggested parts in a kit, they also had easy access to an install video that simplified the install. I purchased two kits - one for my truck and one for my wife's Tahoe. Would highly recommend HR, they explain a lot of things with all the different options and show before and after reviews.
