1. A lamp apparatus for a vehicle wherein a light emitting diode is used as a light source comprising:
- voltage adjustment means for adjusting a voltage to be applied to said light emitting diode; and
a lamp body case formed of a heat radiating member, said voltage adjustment means being attached to said heat radiating member and said light emitting diode being attached to said heat radiating member in a spaced relationship from said voltage adjustment means,wherein the lamp body case includes a bottom wall and a circumferential wall so as to form a tubular-shaped lamp body case having an opening on a side opposite to the bottom wall, and includes a high heat radiating cover covering the opening, andwherein the bottom wall has a greater thickness relative to the circumferential wall of the lamp apparatus such that the light emitting diode is attached to said heat radiating member in the spaced relationship from the voltage adjustment means by a distance corresponding to the thickness of the bottom wall.

Abstract
A lamp or blinker apparatus for a vehicle for saving power and providing a long life and for achieving miniaturization of a lamp body by using a light emitting diode as a light source. The lamp or blinker apparatus for a vehicle includes a front blinker having a light emitting diode as a light source in a lamp body, and a resistance circuit for adjusting the voltage to be applied to the light emitting diode. The resistance circuit is provided separately outside the lamp body. The lamp body case may be formed from a heat transfer member with the light emitting diode attached to the lamp body case.
