Description
This page features one set Error Free No Resistor Required CREE High Power 7440 LED Bulbs w/ Plug-N-Play cancellers, exclusively designed for front turn signal lights or rear turn signal lights ONLY.
This revolutionary US patent pending design allows you to convert the single-filament 7440 turn signal lamp incandescent bulbs to LED without worrying about the annoying hyper flash problem. Everything is plug and play with no modification required.
We have conducted a one year long test base on a 2013 Scion FR-S, a 2010 Nissan 370Z and a 2014 Lexus IS350 for these LED turn signal lights. Everything works great, no hyper flash, no warning error message and there is no need to modify the wire and add extra load resistors!
Note: Since the load resistor will get warm/hot, please make sure to tie or use double-sided tape to place the load resistor to metal.
