Your time and effort and having to drive to the auto parts store again will offset the cost of a HD flasher.

They are usually louder, meaning you will hear the click of them. this will give you a audio signal to your ear that the turn siginal is on, as well as the indicator on the dash.

How many times have you seen people riding down the road with the turn signal ON for miles?

 

Do like the man said and fix the problem. Don't band aid it. Clean all sockets and grounds. Than ya can use an HD flasher as well. But fix the problem first. Unless ya got a dozen lights hooked to your turn sig's, the stock setup will carry the load if it is clean and well grounded. If ya had an open circuit than one light would not blink. A blown bulb is an open circuit. And like the other man said a short is power to ground and will blow a fuse or smoke the wires.

 

As arctic y said.
Corrosion and poor grounds will cause a high resistance. High resistance will cause a higher amperage flow.

 

guess it's time to start scrubbing
