I was wondering if anyone had some insight to help me out here. I have a fleet of tractor trailers. There has been a rash of people all over the country running into the back of parked or disabled trucks. In some cases people are winning large jury awards for accidents which the drivers of the cars were at fault. I won't get into extreme detail here, but what I want is to supplement the warning triangles/flares we are required by law to put out when disabled and the hazard lights.
They make these LED flashers which I have on my pickup, that I want installed on our trailers. Here is the problem. Power is fed to the trailers via what we refer to as a "pigtail". Without power from the vehicle the trailer is dead. I want these lights to come one when the trucks hazard lights are activated, but not when either left or right signal indicator is turned on. My initial thought was a relay (if it exists) that could have two power ins (if that makes sense) from the left and right turn signal. Both of these would need to feed power to the relay before power would be supplied to the flashers. However the problem with that is the power source to the relay would be on off on off due to the flashing of the hazards. The only other continuous power would be the running lights, but obviously we don't want the flashers running just because the lights are on. I don't want any switches that the driver has to remember to turn on/off. If anyone has any ideas how this might be possible, I would certainly appreciate some insight. As well as a source for this elusive relay.
Thanks for any help.
