well... if you don't already have the US spec lighter/recepticle (narrower & deeper to hold plugs better)... just order the upgrade kit from Sunset Porsche. Should be < $25. Might be your only way to order a new light to being with...
Now, if you lived on the other coast, I'd say order from Suncoast but w/ Sunset in your backyard, you cannot go wrong.
Here's a link to the item on Suncoast's site
Good luck
