Because the LEDs don't draw enough amps, the vehicle thinks the light bulbs are out. I used these resistors to convert my Mitsubishi to LED. They've been working great for almost 8 years now. Also, they get redicously hot if the light is on for a long time so mount them carefully. I had one fall onto a pillow in my trunk, (trunk dome light) and melt/burn the foam.
