4Pcs Universal W21/5W 7443 7440 T20 LED Warning Canceller Decoder Car DRL Light Lamp OCB Load Resistor Module Canbus No Error Function: W21/5W 7443 7440 T20 with built in Heat Sink, These LED Load Resistors will overcome the problem with warning errors, bulb blown messages and bulbs flashing, that you get when installing standard LED bulbs to your car, bike or truck. LED bulbs have a lower power consumption compared to conventional incandescent lamps, so that an error message often occurs when replacing them with the modern LED variant. In order not to have to do without the latest LED technology, you can install these load resistors. They replicate the performance characteristics of a light bulb to the system so that it works properly. Feature: Material: Aluminum Cover Quantity: 2 pcs Voltage: 50V, 0.5A Output power: 25w Total length: approx.17.5cm / 6.89" W21/5W 7443 7440 T20 , fitting Built in Heat Sink No wiring or modifications needed Direct Replacement, Plug and Play Will turn any W21/5W 7443 7440 T20 LED into a Canbus bulb Specification: 1.25W 10ohm high power turn signal resistor, 2 load resistors, usually each LED bulb installation requires a resistor connected together. 2.Note: Load resistors can be very hot when working, mount them stably on a metal surface and contact them with any plastic parts to avoid plastic melting. Package Included: 4 x W21/5W 7443 7440 T20 LED Warning Canceller / Decoder 4 xAnti Flicker Resistor Kit Product Show:
