So I installed LED back up lights and LED Brake lights from Super Bright LEDs.com. They are all bright and look great. The reverse lights seem to work normally, but the brake lights start to blink when the turn signal is on, and occasionally even the opposite side blinks. Anyone have experience like this? Do I need to go back to traditional bulbs? Swapped out the interior bulbs and they all work fine. Also, I bought the "Switchback" bulb for the brake light- no idea what that is but maybe that's the issue?
