    I am trying get my strobes to work before the season starts and cant seem to get either one in the rear of my truck to work. The fronts work but no rears. I have checked for voltage going in and i found 11.57 volts without truck running. They just wont light up. I disconnected the connector behing the light and got shocked by somthing so there must be somthing going to the lights. There is adjustable screws in the boxes where the power comes from and i am wondering what they do. You think its the bulbs them selves? Any ideas?

    First of all, what strobes do you have? If you can unplug the fronts and swap them with the rears, you can find out if it is the strobe head or another problem. Check you grounds, too.

    I have no idea what brand they are because they came on the truck. I have ground and power. Each strobe has this little box to power it up. I dont know how else to figure out who makes them

    Can you take a pic?

    If there is a problem with a strobe head, you will need to know what you have in order to get a new one, anyway.

    Chances are a tube is out.
    How did you wire it?

    I didn't wire it. They came in the truck when I got it in October. Only the fronts worked last year. I'm trying to figure it out before it gets cold

    Are they tubes or LEDs?

    Help us identify them.

    Do they look like this? Strobe:

    It doesnt look like that. I will take a pic of them during the day tomorrow. Each strobe has its own little power box if this helps at all.

    I did some testing today and found that if I conect the wires directly to my booster pack i get one flash out of both light then they stop. So strange

    Take a pic of your set up so we can see what you have and can go from there.

    The small case attached to the wire is the lamp driver. Make sure you have the correct wiring. Red-Red/ Black/Black (white/white) / White w/ purple stripe or grey wire is your flash pattern selector. Take a wire from the + term of your vehicle batt run it to the red, ground the wire and see. If that fails this could be a driver issue. However, if both arn't working i would bet its prob a wiring issue. The LED hideaways are not like strobes. You can tap them into your taillights without disrupting the OEM electrical load.
