    I have a light bar like the one posted below but it is blue. My problem is it keeps blowing my fuse for the cig. lighter.

    What amp fuse are you using? A friend of mine had the same thing happen so you used a slightly bigger fuse and hasn't had anymore problems.:waving:

    it has a 20amp fuse already ( thats the one that keeps blowing ). Maybe I should go to a 25 or 30 amp fuse ??

    Is it ok to put bigger fuse's in there ? As I have no problem putting a bigger fuse in the socket.

    Check that the wiring inside the cig plug is not loose and grounding out

    Those lights don't draw much amps. There is something wrong with the cig.lighter socket or the plug, grounding out.

    Something wrong there. Those lights only draw 9 to 10 amps. check the wiring to see if there is any loose connections or wires rubbing.

    if u put a bigger fuse in you could melt wires. what i would do is get rid of the plug and hook it up to a constant power source and put a switch and a inline fuse holder on it. thats how i did the one on my truck and i haven't had any problems with it.

    Have you had the light and it worked OK before or you just get it?
    Could be putting it in and out all the time has made the socket loose or worn out. Might even need to replace it. They are fairly east to replace and parts stores have the whole setup. Check ALL the wiring on both light and socket. The wire that plugs onto the middle of it on the back is positive, the "barrel" is grounded. A full size 8 beam rotator light bar might pull 20 amps but the little one no way.

    If your already using 20 amp fuse, I would not go any bigger than that!:nono: I would replace the cig. lighter. :nod:

    I don't think I am going to put in a bigger fuse. I think I found my problem ............. I ran the wire threw my side window (quad cab)and closed it ............ I think it has pinched the wire causeing a short.

    I think Im going to do what bultemaj suggested.

    Where the hell is everyone else running their wire threw to get it to the cig. lighter plug ??????

    I've got a super cab so I just run mine from the light into the cab between one of the rear doors and the cab. I open and close the door numerous times every day and it never has gotten pinched.:D
