Different Turn Signal Speeds

My left turn signal seems to be blinking at normal speed and my right turn signal is significantly slower. I put a new flasher in and there has been no change. Anybody run into this before?

If its a stock mechanical flasher, you probably have a corroded socket or a marginal bulb.

Inside the stock flasher is just a flat piece of metal that heats up , and it flexes back and forth to turn the bulb on and off. How fast it clicks back and forth depends on the current flow, since that affects how fast it heats up. If you have a bad bulb or corroded socket the amount of current through it will change, which changes the speed of the flasher. The most common problem is corrosion in the light socket or a bulb with the wrong wattage.

You can also buy a replacement electronic flasher, which has a small electronic timer built in. The flashing rate does not depend on current flow, so it will flash the same speed regardless of load (for example, when you plug in trailer lights).

Thanks, I'll check that.

The OEM flashers go out sometimes too. I've only had it happen once in the 38 years I've had a license though. You should be able to swap the one from the hazard lights to confirm this.
