3157 Switchback style bulbs, resistors required, do not work in 2011-16 Ford Superduty 3057 / 3157 / 3357 / 3457 / 4057 / 4157 3-Watt Ultra High Power SMD DUAL COLOR "SWITCHBACK" 360 Degree LED Bulb - WHITE & AMBER ATTN: This new 3-Watt Ultra High Power Dual Color LED Switchback Bulb (Part number REC:264220WA)These bulbs WILL NOT Work in the new 2011+ Ford SUPERDUTY! RECON’s New LED Bulbs Feature extremely low power consumption, have built-in current limiting resistors, generate practically no heat, and boast a longer life expectancy than any other automotive LED bulb currently available. RECON LED bulbs have an average life expectancy of up to 80,000 hours. LED bulbs may cause some newer vehicles to indicate a bulb is burnt out (because of their low power consumption). Some cars indicate this by increasing the flash rate of the turn signals, some turn on a bad bulb indicator. This can be remedied with our Load Resistors wired across the turn signal bulbs to simulate a filament bulb load. This 6 Ohm, 50 Watt resistors can be connected across the turn signal bulbs to simulate the load of a regular filament bulb (2 Amp load). This will solve LED related turn signal problems such as hyper flashing or burnt out bulb indications. This LED Load Resistor can be use with most signal or brake light which uses SINGLE or DUAL FILAMENT LED light bulbs, like the 7443, 1157, 3157, 3357, 3457, 4057, 4157, 1156, 7440, 3156 etc. Recon Accessories 264220WA
