if you're going to retrofit the headlights, just buy the already blackhoused ones off of ebay in the style you like. ebay headlights are known to not have that great of light output, but with a retrofit, that doesn't matter. if you tape off your current headlights, the tape may peel off some of the chrome since they're so old now...i remember that stuff happening to people back when i got my first accord in 2004 haha, so i'd say the chances are greater now.
when i did my retros on my second accord, i used ebay headlights and taped them off when i blackhoused them. i didn't have any problems with the chrome peeling off with the tape when i removed it.
