RECONs 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.
