Angel eyes are round light lenses that glow. They are more of a halo than an angels eye although I cannot admit to having seen an angel. The style was popularised by BMW and now aftermarket angel eye kits are available for most cars. This Citroen Saxo has a quad angel eye headlight conversion and even angel eye fog lights. They look best at dusk, with the full lights on you really do not get to appreciate the subtle effect of the angel eye. Combined with a bad boy bonnet this is a really cool look.
