most modern housings have a metal shield or other means to alter the light pattern to try not to blind the other drivers. some lamp housings can be tweaked to fix the RHD / LHD problem.

I think my lamps are the wrong sidages, the cut is on the passenger sider, or is on the lamp in the drivers side, maybe i just need to swap them.

that's the fun with those upgrade housings for the h4/9004 bulbs is they tend to be rather inconsistent and poorly labeled, this is the second set, the first ones were worse.

If you really want to change out the sealed beams, get good housings like from hella or someone.
