Vehicle lamp
A vehicle lamp is provided having a heat sink having a first end mounted to a lamp housing and having a free distal end extending into a light chamber adjacent a central optical axis of the lamp. A light emitting diode (LED) is mounted adjacent the distal end of the heat sink to have a central light emitting axis opposite the optical axis of the lamp. A parabolic reflector is positioned rearward of the heat sink, a parabolic reflective surface extending at an upper and lower solid angle relative to the LED, wherein the upper and lower combined solid angle is greater than a half-paraboloid.

Method and apparatus for a signal indicator light
A lighting module is shown and described having a housing with an opening therethrough. A forward portion of the opening may be enclosed by a cap and a rearward portion of the opening may be enclosed by a transparent media. A second media may extend from the opening through a wall of the housing. The cap may be securable to a bar via a mounting apparatus. A PCBA with one or more operational groups of LEDs may be secured within the opening, such that light may be emitted through the media. A second PCBA with one or more operational groups of LEDs may be secured within the opening, such that light may be emitted through the second media. Each operational group may be integrated with a control system of a vehicle, and may be operated individually or collectively. Each operational group may correspond to similar or different colors of light.

Vehicular exterior mirror system with light module
A vehicular lighted exterior rearview mirror system includes a lighted exterior rearview mirror assembly and a light module disposed thereat. The light module includes at least three forward illuminating illumination sources that, with the lighted exterior rearview mirror assembly attached at the side of the vehicle, are arranged spaced apart at the lighted exterior rearview mirror assembly. With the lighted exterior rearview mirror assembly attached at the side of the equipped vehicle, the at least three forward illuminating illumination sources, when powered, emit light at least in a forward direction with respect to the vehicle. The light module includes a turn signal indicating illumination source and a light piping element. The light piping element guides light emitted by the turn signal indicating illumination source along the light piping element so as to emanate from the light module at an outboard portion of the mirror casing.
Rotation light source lamp system for reducing chromatic aberration and vehicle using the same
A rotation light source lamp system is combined with a rotation light source device in which a chromatic aberration correction unit obviates focal distance differences occurring between incident paths “a” of lights emitted by LED light sources sequentially synchronized and turned on when first to N-th LED chips arrive at a location where each LED chip faces a signal transmitter while the first to N-th LED chips are rotated once in response to the application of a lamp turn-on signal for the vehicle from the signal transmitter. Chromatic aberration can be reduced by correcting a difference between refractive indices for each wavelength having a different color in the first to N-th LED chips.
