I recently bought a LED DIY kit to save some money. After staying up all night soldering countless LED's. I wired the LED's to the ballast, and then the ballast to the potentiometer and then to the power cord. THey turn on but the flash about every second or two. Also if i turn up the "pot" it will just brighten the flashing. Frustrating as all get out. Any help will be needed. Thanks.
