Turn signal issues with LED bulbs

LED brake/tail lamps will not flash with thermal flasher units due to their extremely low current draw. Also, with stock flasher units, the turn signals may flash faster than normal (Hyper-Flash). These installations will require an electronic flasher unit, available at your auto parts store. Try to find flashers designed to work with LED bulbs, they will say "LED compatible". Often HEAVY DUTY flashers will also work with LED bulbs.

Another fix is the installation of Load Resistors which are wired across (in parallel with) the turn signal bulbs to simulate the load of a standard filament bulb. One load resister per bulb.

Warning: Load resisters heat up like a lightbulb. They must be installed to make no contact with plastic or paint.

LED bulbs will dim with your dash light intensity control.

LED bulb Flasher Unit

Electronic LED Flashers have no minimum load-12VDC.
Eliminates the need for load resistors, turn signals will flash at normal rate with or without LED bulbs.
