sequential flashers and LEDs
I've recently discovered the primary flaw with LED lights as turn signals...the curent used to drive them is so small it causes the flasher to think the bulb is out (and gives the high speed flash)
I bought my mom a sequential taillight flasher from T-cat (on ebay) and dad got her some of the LED taillights. Is there any load resistor i can install to fool the flasher into thinking it has a full current load?
thanks

Yes, you can add a load resister to each bulb. I bought 6 for my car - can't remember where now.

try a 47 ohm five-watt resistor. That will add an additional 250ma load @ 12v to whatever the LED tail lights draw on their own. If that doesn't work, then try a 33 ohm five-watt resistor (which would add another 350ma load).

Try an electonics supply store or Radio Shack.
Reading this thread got me thinking about a problem I'm having with towing my tire trailer behind my 87 coupe. The factory turn signal flasher works great until I hook up the trailer wiring; with the addition of 1 extra bulb from the trailer, the turn signal flasher wil not allow the bulbs to flash very brightly and the blink rate is more rapid.
With a standard flasher, a burned-out bulb will typically stop the flasher from working. The resistance in the circuit drops off and the flasher depends on a specific resistance in order to work. With an extra bulb, the resistance load is higher so the flasher can't work properly because of the extra load.
The flasher is tucked up to where I would probably have to rip half the dash out to replace it with a HD unit. So will using an LED bulb (1156 replacement) solve a flashing issue like this?
