I put these on my motorcycle mirrors so that when the turn signal is on everybody sees it flashing bright red even in the daylight. Works like a charm.As soon as they go on I see cars backing off. We're very civil here. LOL! Mounted them on the inside of the mirror cavity and they're clear when off, can hardly notice them.. Now I'm tossing around ideas where they go on the Cross. Looks really good!!!! I was thinking of mounting some in white behind the grill for that look
