I didn't black those tail lights out. I tried to black-out some clear ones, but it didn't look right. When I cruising around ebay about 1-1/2 yr ago, somebody was selling them for $100 shipped (new) and I said what the hell To my surprise they look awesome at night, and during the day dark with a tad blue tint. However, I've been very lucky around my area. During the day time, cops love to nail you for these lights. During the night time they can't tell very well, but if you have them on, pray that no cop is behind you.
My only complaint about these lights is that when I replaced them, with red bulbs, I have my rear tail light indicator on my dash telling me my lights are out (which they are not). Some day if I have nothing better to do, I'll find out which bulb is screwing up.
