LED side marker lamps

Hi all, I am replacing the old bulb type side marker lamps on my
trailer with the new LED ones. I purchased a tridon 2 pin solid state
flasher to replace the old one. My problem is that now the new LED
lights stay on and do not flash. Help!
Thanks in advance

What is the amps draw of the lamps? What is the amps rating of the flasher?

You must put a power resistor (maybe 10Watt) in shunt with the new bulb so
the resistor + LEDs takes the same power as the old bulb.
If you think you've problems then talk to the poor 'ole truck manufacturers
who use computer controlled CAN bus polling systems programmed only to
detect incandescent bulb failures.

I've heard of a "Heavy Duty" flasher that doesn't depend on the load
current to give it its flash rate. This is the kind that will still
flash if you lose one of the bulbs (i.e., front or rear), albeit
probably slower, so you'll know you have a bulb out.

Good Luck!

The phrase I remember from an owner's manual is "variable-load flasher."
They were originally designed for vehicles with trailers.

I know the local auto parts dealer has a "Heavy Duty Electronic
Flasher" that uses a timer and a relay to set the flash rate, not a
bimetallic strip.

The primitive, electromechanical, bimettalic strip flashers are dead simple,
cost nothing, last for ever and have built in bulb failure indication.
Difficult to emulate using modern technology. The number of homebrew
transistorised versions I've seen is legion. In not one of them, have the
authors figured a way to provide useful bulb fail alarm. (or even recognised
it came as a standard feature of the mechanical versions).
