Carbide Canbus 2.0 T20 3156/3157 LED Bulb Pair

The GTR Lighting Carbide Series 2.0 LED replacement bulbs, model GTR.LED583-2PK, are designed to be the brightest option available, offering enhanced safety and style. These white bulbs replace T20 based 3156/3157 series bulbs, including cross-references for 3057, 3157, 3457, 4057, and 4157. Featuring a built-in CANBUS integration circuit, these bulbs work with approximately 95% of cars, trucks, and motorcycles, eliminating the need for external resistors or flasher module replacements. The Carbide Series 2.0 boasts an Intelligent Temperature Control System (ITCS) with an aluminum case, vents, and heat sink fins to manage heat effectively. A Constant Current Driver ensures reliability by regulating voltage fluctuations, extending the lifespan of the LEDs. Each pair produces 2,400 raw lumens, making them a powerful lighting upgrade. These bulbs are polarity specific; if they do not turn on, try flipping them around. If they stop working, it indicates they have overheated and the protection circuit has shut down; allow them to cool for 2 minutes. It's important to note that these bulbs will only work with Standard style wiring, not CK style wiring. While the CANBUS integration works for most vehicles, some specific models may still require traditional LED bulbs paired with a resistor for turn signal applications, including the 2012-2017 Toyota Camry, 2015 Dodge Ram, and 2018-2019 Subaru Crosstrek. Conversely, the 2018 Dodge Durango, 2019 Jeep Wrangler, 2018 Toyota 4Runner, and 2019 Ram 1500 are confirmed to work without resistors. The GTR Lighting Carbide Series 2.0 LED bulbs come with a 2-year warranty.
