In the case of many cars, aren't the running lights and turn signals in the same bulb?

What about the case such as the brake/tail/turn lights? They'd all be governed by 3 circuits going to the same bulb, right?

So you'd have a dual intensity LED setup with a blinker added in, in that case.

I dunno, if I were going to make lights for a car (or other vehicle) I'd just make them for all the lights to keep things looking the same.

Question -
Has anyone ever checked the energy use before the blinker relay? Relays use energy, too, so the total value for the turn signals would be all the signals and the relays for that side, and blinking. Doesn't it take more energy to turn an incandescent bulb on and off than to leave it on for a minute? (Or is that a myth?)
