921/T15: GTR Lighting Carbide 2.0 (Resistor-Free)
BULBS: 2x 921/T15 GTR Lighting Carbide Canbus 2.0 LED Bulbs
WARRANTY: 2 Years
CARBIDE CANBUS 2.0: The Carbide Series LED replacement bulbs from GTR Lighting were originally designed to be the brightest option in the world and today with the version 2.0 they’re even brighter! Because these bulbs are the brightest option available today you will experience greater safety from a brighter light, better performance through built-in CANBUS integration, and better style with the beautiful colors created by the custom built LED chips!
NOT JUST THE BRIGHTEST, BUT ALSO THE EASIEST! In the past you had to wire in resistors to your turn signal bulb circuits in order to trick the computer into thinking that your LED bulbs were the same thing as your old dim bulbs. Not anymore! The new Carbide Series 2.0 bulbs have a built-in CANBUS-integration circuit that works with 95% of all cars, trucks, and motorcycles on the road today! Gone are the days of wiring in resistors, or replacing flasher modules. These new LED bulbs are truly plug and play, and one of the brightest and most reliable options around.
ITCS – INTELLIGENT TEMPERATURE CONTROL SYSTEM: The Carbide Series 2.0 CANBUS LED bulbs have a unique physical design as well as a temperature controlled thermistor circuit to protect the bulbs from overheating. The aluminum case of the bulbs is larger than others in order to accommodate the extra heat given off by these bulbs. There are strategically placed vents and heat sink fins at the top of every bulb to maximize passive cooling.
NOTES: Please take these things in consideration before using these next-gen LED bulb upgrades: Some vehicle still need to use a traditional type of LED bulb and a resistor for turn signal applications – there are thousands of different applications and the technology does not exist yet to make a product that works for every single vehicle on the road. For example, these vehicles do not work without resistors, they still require the traditional type of LED bulbs, like Armor Series, paired with a resistor for turn signal applications: 2012-2017 Toyota Camry, 2015 Dodge Ram, 2018-2019 Subaru Crosstrek. The following vehicles work without resistors when using the Carbide Series 2.0 LED bulbs. These are confirmed to work without resistors for turn signals, no rapid flashing problems, no hyper flash, and no bulb out errors: 2018 Dodge Durango, 2019 Jeep Wrangler, 2018 Toyota 4Runner, 2019 Ram 1500. These bulbs are polarity specific. If they do not turn on, please try flipping it around in the socket and try again. If the bulbs stop working it means they got too hot and the protection circuit shut down. Please try to cool them down for 2 minutes and try again to troubleshoot the problem.
