Taillights and their plastic casing has traditionally been red, which enticed teenagers and tuning enthusiasts in the 90s to convert the taillights of cheap cars (Honda Civic, Mitsubishi Eclipse, Nissan Sentra, etc.) from red to chrome. However, earlier this decade, a short-lived trend emerged where automakers incorporated the chrome taillights as stock. I don't see many examples anymore...the fad did not hold. I particularly never understood why Lexus used chrome taillights on the last-gen IS (above), but it must not have been popular because the current model uses red taillights. The demographic Lexus was going after for the IS was entry-luxury / above-average income, but the taillights suggested a teenager demographic; there was a clear disconnect.
