HMMM,,I just read that you cant use your regular flasher with these LED units. Now You hafta buy a special electronic flasher.
More $$$ ?
I just bought the extra bright 1157's at about 1.00 ea.
Still trying to figure out the special flasher needed part?
Funny because when our shop started installing LED lights in our trailers as replacements to the bulb type, no special flasher was needed! The stock flasher worked fine with the LED's!
