  Flashing the brake light saves a wire or two, reduces the bulb count by two, and avoids another bulb housing. Plus it's allowed in the spec and makes your car look older and more dignified. (Remember when we had to blink our brakelights because times were tough? We're still tough!) Some pickup trucks are wired for either, and you can swap out the lenses and add a bulb to get separate signals.

  In the US, there's a regulation mandating the size of the lit area for the turn signal exceed a certain surface area. The European style amber signal area on most standard-sized or small cars is unlikely to comply. This (and regulations around the amount of red reflector in taillights) is the reason why most Americanized cars get terrible taillights with reused brake lights.
