    Default Problems with flashers. k1500 1997

    My k1500 1997 had problems when I left so blink blink it really fast just like a lamp is broken. have tried to take out all the lights one by one, but there will be no difference.
    know someone it may be the relay?

    Check the sockets for the taillight bulbs if there is scorching (brown or black) it is shot, you can get new ones for under $25, this is very common for those models of trucks with those taillights

    Default Heavy duty flasher

    Welcome. Try replacing the flasher with a heavy duty trailer type.

    From: Cooper Bussman

    • Specified vs. Variable Load - specific load flashers are designed to flash only a certain number of bulbs. Variable load flashers can handle a range of amps, such as is required with a trailer in tow.
    • Bulb Capacity - designates the total number of bulbs in the circuit for left or right directional signal.
    • Number of Terminals - select either a two or three blade terminal flasher to match the socket in the panel.

    Get the Grote thermo mechanical flasher for up to 16 lamps from Amazon: [ame=""] Grote 44700 Electrictronic 16-Lamp Flasher: Automotive[/ame]

    I like the Grote because it is louder than the stock flasher.
