Just wondering if you can convert the high priced headlights in my 05 CLK 320 back to the earlier style headlight assemblies. The reason for this is I called for a headlight bulb and they told me it was 105 buck, that is ridiculous. I also don't like the idea of them having modules and all the other high priced items. How hard would it be to swap them back, are the plugs the same?
