Mine were still there but falling off after 1-1/2 years of ownership...so I used clear RTV to re-install them. As others have mentioned in previous posts 3M makes a weatherstripping adhesive too for this purpose.
As far as I know the purpose of the gaskets was primarily to prevent wind noise (aka whistling) from air rushing in around the headlights at highway speed. Also seem to help with rain entering engine compartment too.
For those of you that are missing them and would like to try and buy them I suggest calling St. Charles Isuzu for price/availability.
