My LED turn signals don't work right: Difference between revisions

Older vehicle flashers were mechanical. They had a small piece of springy metal in the relay body, and as it heated up from current flow it flashed the signals. Mechanical flashers will increase or decrease in rate as voltage or current changes because the springy metal bit heats up at different rates.

The stock EX250 flasher is solid state, but it doesn't use a timer. This is why its flash rate varies with bulb load, like an old mechanical flasher. With mechanical flashers, the flash rate is determined by the bulb load. As more bulbs are added, the current through the heater element increases and causes it to heat faster, breaking the contacts faster and resulting in a faster flash rate. The Ninja's solid-state flasher reacts the opposite, flashing faster with the reduced bulb load from lower-current LEDs. Fixed-rate flasher modules (like the new one you're putting in) use a timer to regulate the flash rate independently of bulb loading.

The stock EX250 flasher is solid state, but it's fairly simple, just a chip with a cap and a resistor or two. It doesn't use a timer, though. This is why its flash rate varies with bulb load, like an old mechanical flasher. With mechanical flashers, the flash rate is determined by the bulb load. As more bulbs are added, the current through the heater element increases and causes it to heat faster, breaking the contacts faster and resulting in a faster flash rate. The Ninja's solid-state flasher reacts the opposite, flashing faster with the reduced bulb load from lower-current LEDs. Fixed-rate flasher modules (like the new one you're putting in) use a timer to regulate the flash rate independently of bulb loading.
