Why would you be worried about transferring them over. All the states that have accepted the unified traffic regulations have outlawed their use except in fog. As we have very little fog in this country they are not worth moving over to the new bar.
They are also not very effective in fog either as their beam spread is not very well controlled. Too much of the light goes up above the horizontal axis, this is one of the reasons they are banned - the uncontrolled light affects too many other drivers. If you want to use fog lights then get some well engineered ones that are effective in fog. Those cheap ones that are supplied with new vehicles are just cosmetic wanker lights.
