Each 7443 LED light bulb with dual function wedge base, features 12 pieces SMD-3030 and clear projector lens to deliver 3000K amber yellow and super bright 1800 lumens @ total 7 Watts. Polarity sensitive, if it couldn't light up, please flip plug and try again. It can only be applied to standard 7443 bulb other than 7443-CK type. LED bulb has bigger dimension than original bulb, please check if your car has enough space for installation.
Built-in IC Circuit of wide and low voltage Range 12-24V to prevent 7443 LED Bulb from being damaged by voltage variation and spikes. LED Light lamp is widely used as perfect replacement for vehicles, car, van, caravan, RV camper, 5th wheel, motorhome, motorcycle, truck, lorry, trailer, SUV, pickups, Jeep, marine, boat, sailboat, yacht, and other low voltage 12V/24V automotives.
7443 LED bulb is NEITHER CanBus error free NOR anti-hyper flashing. 50W 6OHM load resistor decoders or flasher relay may be required to ensure the LED bulbs light up with full power and prevent LED bulbs from being hyper flashing of turn signal light, blinking, flickering, warning or any malfunction error code on dashboard.

Product Description

You may need extra load resistor

For some CANBus vehicles, the electronic computer may detect the wattage loss after installing LED bulb, it then may launch warning message to drivers, such as bulb hyper flashing, flickering, radio interference, malfunction error code on dashboard. At this moment, you need to install extra 50W 6OHM load resistors to help reach the same wattage that halogen produced, and then eliminate the malfunction.
