    i bought an 08 2500hd chevy that had 6 hidden strobe bulbs already installed. i bought a sps660 strobe controler from ebay and hooked them up and they worked great.

    i thought i would get a 90w conrtoller so i got an sps690 and they only worked for a little while then quit now a flash once in a while is all i can get out of it.

    is there watt ratings on the bulbs? all the replacement bulbs i can find dont say anything about watts.

    thanks in advance

    Thats only 15 watts per bulb.......they should easily handle that. Try unpluging one cable to a bulb at a time You may have a grounded wire somewhere. Mine started doing random flashes and it was a bad bulb. once it was unpluged they fired as usual.
    Do they still work on the 60 watt unit?

    Try them individually on a circuit from the power supply that you know works. If it still dosent work there's a problem with the bulb. If it does work, it's a problem with the previous outlett on the power supply that wasn't working. I'm thinking a bad power supply... The two extra legs of it. There's 4 together than the extra 2. If both the extra 2 circuits aren't working together, be sure you have the trigger wire connected right.

    There's 2 switch wires that need 12v for all 6 to flash, did you connect them both? One should do 4 outputs, the other should do 2.
