the leveler has nothing to do with what globes u have if you have zennon lights converted or not they have a motor built into the headlight unit.if its not working check the wiring as bryce said ...diferent compliance places have different methods and wierd ideas on how to disable the zennons.the shop that did yunis,s car removed the ballasts and fitted machined aluminium plugs to blank off the hole in the light where the ballast fitted but his levelers were still operational.i did manage to rewire his and refit the zennons tho even tho they hacked them so close to the ballast and left fark all to solder too.at least they returned all the bits and pieces including all cables and plugs and globes .could also depend on where they cut the power and rewired to suit the halogen globes.like i said they all seem to do it diferently .............regards mike
