Flashers for LED applications

The correct Flashers are becoming increasingly noticeable
as LED lamps are used on vehicles as tail and brake lights and sometimes
front parking and turn.
These lamps draw little or no juice that is required to
make a mechanical flasher we have used and relied on for years to
operate. Normal 552 flashers, the standard of the industry require 1-3
amps load before they will flash. Just a burned out bulb in the back f
your car prevented the front light from blinking.
The same is true when the LED’s draw about one (1) amp
per one hundred (100) bulbs. That means you need 2-300 LEDs in you
lights to operate the standard flasher. Regular 1157's, Brite bulbs (R)
and some Halogen bulbs will operate with standard flashers OK. Some
Halogens draw enough juice that the flasher speed might be effected.
LED’s require additional resistance to flash the 552 unit. An extra bulb
under the dash will work, but at night you will be forever reminded that
you chose the cheap way out.
Electronic flashers designed for LED applications should
be able to carry as little a load as you have or be able to carry a
regular bulb up front and Led’s in the rear or whatever combination you
have. Many Electronic flashers cannot carry a incandescent bulb and an
LED both.
