    I bought a hella mini light bar with a cigarette lighter plug. I wanted to convert it to a permanent wired light using the over head switch that comes with Chevy plow package. well I cut the plug off and wired it up with the hot and ground. left the white wire which is for the patern change unconnected. instructions say to advance the pattern in a permanent mount to just touch this wire yo ground. not sure what I did wrong. I tried hooking it back up to the cigarette lighter plug but I only get one lens to work. I think its
    toast but wanted to check.

    its a hella/optilux led. the permanent mount instructions say to use the white wire to ground momentarily for pattern change. I didn't have that wire even hooked up. only thing I can think of is that Chevy made the green wire hot and black ground.

    Many lights use ground to change the flash patterns. IN your truck the black wire would be ground and the green +12 volts. If you reversed those 2 that could be the issue. I would put a meter to those wires to be sure.

    Yep thats what I did, Hope I can buy just the circuit board. The light is a Optilux/ Hella OS-L400.

    I bet a simple test light would have been cheaper than a replacement board, leason learned I hope !!!

    Not trying to add insult to injury here but like the old saying measure twice cut once really applies here !!!

    Correct....green is positive...

    i am surprised it blew the board....usually leds don't really care if you hook up backwards...tir3 and such..

    Thanks for the referral R&R......good to know people remember me.

    this bar??

    ok....looking at that bar i think your gonna need the smaller unit...

    IF you want.....send me the bar and I can rewire it for you.....otherwise just use this flasher and split the leds in the bar half on one output and half on the other.

    email Louis at SNM

    and tell him Dissociative off plowsite told you to order this flasher..


    He takes care or me pretty good....should take care of you too.
