GTR Lighting GTR.LED456 Carbide Canbus 2.0 LED Bulb 4257 Amber

The GTR Lighting Carbide Canbus 2.0 LED bulb in 4257 size delivers exceptional brightness and reliability for turn signal, side marker, and daytime running light applications. This amber LED bulb features built-in CANBUS integration to eliminate hyper-flash and bulb-out error messages without the need for external resistors or load equalizers on most vehicles.

Key Features:

• Built-in CANBUS integration works with 95% of vehicles to prevent rapid flash and error codes
• Constant Current Driver regulates voltage fluctuations for longer bulb life and consistent performance
• Intelligent Temperature Control System (ITCS) with thermistor circuit prevents overheating
• 1,200 lumens per bulb for significantly brighter output than factory incandescent bulbs
• Advanced 2835 SMD LED chips for high-efficiency light output
• Aluminum heat sink with strategically placed vents and cooling fins for optimal thermal management
• Plug-and-play installation with no modification required
• Compatible with CK Style, SACK style, and traditional socket types

The Carbide Series 2.0 represents the next generation of automotive LED technology, combining extreme brightness with sophisticated electronics. The constant current driver smooths incoming voltage to provide a steady stream of power to the LED, protecting against electrical system fluctuations and extending bulb life. The enlarged aluminum housing and heat sink design ensure these high-output LEDs stay cool even during extended use.

Note: Some vehicles may still require load resistors. A small percentage of vehicles (including certain 2012-2017 Toyota Camry, 2015 Dodge Ram, and 2018-2019 Subaru Crosstrek models) may need traditional LED bulbs with separate resistors. These bulbs are polarity sensitive - if they don't light up initially, simply flip them around in the socket.
