Emergency Flashers Hyper-flashing

My 2004 Coachmen Sportscoach emergency flashers are hyper flashing. I think I may need to replace the flasher relay but I can't find it. I've looked through all the paperwork that came with the (used) coach and haven't been able to find an answer. Google was no help at all. Any suggestions?

    That's what I was going to say as well. That's what usually happens when 1 bulb is out to alert the driver to the problem. This can also happens if you tried to put an LED bulb where a standard bulb used to be.

    I was just considering replacing regular bulbs with LEDs

    How do you prevent this flashing then?

    Free,

    You have to look at your current flasher, it will be two or three pin. Then go get an electronic constant rate flasher with the same pin count. But, now it will not change when a bulb goes out....
    Some require you to add a ground wire.

    By the load resistors from the LED light supplier. Super Bright sells them, where I got mine. An electronic flasher unit will also work with LED lights with no resistors. Your choice.

    Replacing all the bulbs with LED's will CAUSE this problem.

    So will a burned out bulb.

    THe flasher is designed to flash X lamps. There is no relay it is a flasher.

    They do make HEAVY DUTY Flashers. 2 lamps or 20. they don't care.
