Description


Best Performance in Industry. 

Our Ultra Bright 24W 1200LM Wt21 4257 Amber LED W/ Built-in Resistors DRL and/or Turn Signal Light Bulbs, No hyper flash (2 Pieces) are amber colored type LED lights that cover 360 degrees to provide maximum output. Unlike other brands, with resistors on both the filament, we created a CANBUS LED that only has a built-in resistor only on the turn signal filament. Having a resistor on both the filament will lead to melting the housing or the LED falling apart in the housing. We even took it one step future to insure the longevity of the bulbs by adding a cooling fan. The fan only turns on when the turn signal is on, to reduce heat when resistor is on.  Our Design protects the LED from being exposed to constant heat eliminating this issue. This assures no hyper-flashing or error codes. Our LED is designed to replace the factory incandescent bulb without the need to add extra resistors or parts.

Best-In-Class Brightness. 

Each LED is equipped with 54 SMD LEDs Amber Colored type LED lights 360 degrees to provide the max output. Each bulbs is 1200Lm, your turn signals will shine a lot brighter than the stock incandescent bulb.

You’ll be hard-pressed to find a brighter, more efficient LED bulb on the market! Designed here in the USA, these bulbs feature an impressive 54 amber color LED chip design.

Installation

Difficulty Level: Beginner - Simple Installation for anyone.

Installation time is approximately 10 minutes. There is no need for slicing or complicated wiring. This light is a plug-n-play installation and operation.
