After install, these bulbs stay on and don’t flash when I use my turn signal.

Your flasher requires an electric current greater than a minimum to flow In the light circuit. You can replace the flasher with one that doesn’t require that current (power is saved), or you can connect resistors, 8-10 Ohms, 25 Watt, in parallel with the leds (power wasted)

Are these polarity sensitive? I have an issue of feedback to my instrument cluster turn indicators when I hit my brakes.

Is it only the cluster turn indicators that come on when you hit the brakes, or do other lights come on? Do the brake lights on your car double as turn signal lights? If it is only the turn signal indicators, and your brake lights are also used as rear turn signal lights, then you need to do one of the following: A) Install load resistors. B) Replace your turn signal flasher with one that is designed to be used with LED bulbs. C) Go back to using incandescent bulbs. There is different issue: With some LED bulbs that replace two filament incandescent bulbs, when you hit the brakes, some current feeds back into the tail light circuit. This can result in current flowing to the front parking lights, the side marker lights, and the instrument cluster back light. If this is your problem, you can do one of these things: A) Go back to incandescent bulbs. B) Try to replace these LED bulbs with a model designed to avoid this problem. C) Have someone design and install a circuit with diodes to block the feedback.
