Black out kit
are these better? http://www.ecklers.com/product.asp?p...4&dept_id=1347

I've had blackout bubble lenses in mine for 5+ years and they never came out. I think they are just held in by a thin bead of silicon.
The ones you linked to are just static clings. They will work, but may not give you the look you are going for. There is also the free mod if you want to try it... I don't know how easy the late C4's are to get the lense off, but cover each one in black panty hose. I saw this suggestion once in person and it looked really good and really worked
well. Light shined through with no issues and it was totally blacked out.
Cost is probably free by asking the wife/gf/mom/sister for a wore out pair of black hose.
Good luck!
Had the blackout look during the day, and the louvered look when the lights were on.
I also had the front static blackouts, they were nice too, fit much better.
