These look interesting too and may be brighter than stock during the day. Anybody heard of a 'remote phosphor' coated lense around a single forward facing LED before? If the bulb really takes 7 watts of power, it may be a very bright bulb (truly brighter than stock). The same Ebay seller has a cheaper bulb with a forward facing LED with a lense and some side LEDs but only a 1 year warranty instead of 5, so this may be more reliable and brighter. Basically I am going for the brightest LED tail lights for my '99 Civic as possible while being reliable
Turn signals are next but doing 1 thing at a time. Side effect is fuel savings but primarily more brightness.
