No washers. I think that the filler may be a generic part of the headlight, not something installed by Jeep. The headlight manufacturer probably sells them with or without washers, but with the same housing.
It's a shame that the best Jeep could negotiate from the vendor, that a best gets a 'they're not too bad'.
There are so many little things that could have been done better ... but too late for this model year.
