I installed these Auxito LED bulbs in my F250 for turn signals. These lights were the perfect fit for my truck replacing the turn signal halogens at all four corners. I avoided the hyper- flashing problem by purchasing a new flasher relay module, designed for LED lights. This is a much simpler resolve than installing load resistors and for about $20, why would you bother mucking around with existing wiring? All said, I am very pleased with the improved aesthetics and function and the ease of installation. https://www.auxito.com/collections/2005-2010-ford-f250-parts-and-accessories-upgrade
