Yeah, most LED tails are setup 'normally'. IE, top section, bottom section, reverse section. Both main sections are red only, with one running as the running lights and turns, while the other is exclusively brake lights. And, of course, the reverse section is white only running as reverse lights.
What I want is a two section light only with two switchback bulbs. One red/white, the other red/amber. The latter on top, and the former on the bottom. Both run in red as the running lights and brake lights, but the tops go "off-amber-off-amber" for the turn signals, then switch back to normal function when the turn signal ends. And the bottom set will change from red to white when reverse is engaged, and lock out the red function, but, of course, you'll then have the tops as reds for running and brake lights.
Also, the housing will have black interiors and clear lenses for aesthetics. It would also likely have a red reflector rim all the way around it and splitting the two sections, for safety. This would not be lit up by the lights, themselves. The bulbs themselves would -hopefully- be those nice JDM Astar lights, but I've yet to find a red-yellow/amber and red-white switchback bulb by them.
In any case, if I could find them, both bulbs would be the full barrel LED with projector tip style, in either a silver or black casing.
Basically, those would be my dream tails. And, if a bulb went out, it'd be a lot easier to replace -as far as I can tell-than one of these LED array type lights.
