I now had time to remove the grille on my Syncro and check these lights, and you
got it all right! These holes are there to help moisture get out, and shall not
be covered by the rubber boot. Water does NOT enter the head light, I have never
had any problem with that, either by high pressure water hoses or car washing
machines or rain for that matter. As long as you install the headlights
correctly, you shouldnt have any problem.
