LED retrofit vehicle signaling lamp with projection LED light source, smartphone app for controlling it and corresponding system
An LED retrofit signaling lamp is described herein. The lamp includes a lamp body, which includes a cap, a projection part, and a burner part between the cap and the projection part. Power contacts are exposed from the cap. A projection LED light source is provided in the projection part and angled to provide a projected image near to the vehicle when activated. A signaling LED light source is provided in the burner part angled to emit non-projected light via the projection part at angles that avoid the emitted light being blocked by the projection LED light source. The projection LED light source and the signaling LED light source are electrically coupled to the power contacts in parallel to each other.
