Hyper flashing is a common problem that can occur when upgrading your car's headlights to LED bulbs. The problem occurs when the new LED bulbs draw less power than the factory halogen bulbs, causing the turn signal relay to think there is a bulb failure. This will cause the turn signals to flash faster than normal, or in some cases, not at all. There are a few ways to fix this problem:
1. Use a load resistor: This is the most common and effective solution. Load resistors are placed in line with the LED bulbs and mimic the power draw of a factory halogen bulb. This will fool the turn signal relay into thinking everything is working correctly and allow it to operate at its normal speed.
2. Use a diode kit: A diode kit works by redirecting some of the power from the brake light circuit back into the turn signal circuit, giving it enough power to function properly. This solution is less common but can be just as effective as using load resistors.
3. Upgrade your turn signal relay: If you're still having problems after trying one of the previous solutions, you may need to upgrade your turn signal relay to one that is designed for use with LED bulbs. This should be a last resort option, as it involves more work than using load resistors or a diode kit
