The lights work fine with a Loksound chip, once the tiny switch three is moved on the circuit board to position 1. For six function decoders, I was trying a Zimo 634D yesterday and all except Halo were working (again once switch three out in right place). It seems a change to CV8 maybe all that is needed to get the Halos working (i.e. No rewiring) but I can't try as don't have a DCC controller set up at home.
