replace relay with solid state device
- I have a car that I tow behind my motor home and wish to make a rear
light strip to fasten to it. it would echo the turn signals on the
light bar. In the old days i would have hooked up a 12 volt relay
activated by the light i was trying to echo. but there must be a
cooler way to do it with solid state materials.
with relays i would pick the relay with the light i was echoing and
it would then activate the relay and pass thru the battery voltage to
the light on the light bar.
the basic problem when you add the additional lights to an exhisting
light load on the towing vehicle it effects the flashing time.
I would use a single power line to power all the lights. and the
source of this power would be the front vehicle. (motor home)
On foreign vehicles - they often use a separate brake light and
separate turn signal light. On American cars they share the brake
light and turn signal light. it would be nice if the circuitry would
handle either system driving the light bar as a combined turn/break
thanks for your help
