Outer Limits 4x4 Board

hey just brought some spot lights that come with wiring put it all in no troubles fllowed the instructions to do it as well then out of blue stop working so re did all connections still nothing so checked the fuse and it was fine then put it back together then it worked but so i am thinking that there it is something to do with the fuse any ideas ?

could of been a bad earth, bad connection some where

try re-crimping all your connections and if your lights are running a ground earth ie. grounded through their own mount check the contact between them and bullbar as well as your bullbar to chassis. Might pay to run a seperate earth as have done with mine, to be sure.
