The invention is an indicator lamp for warning signal to a person who
approaches the vehicle to steal a vehicle. The indicator lamp includes a
lamp unit including a light emitting diode (LED). The indicator lamp
includes a light guide including an elongated portion and a cover
portion. The elongated portion receives a light from the LED at one end
and conveys the light to a light emitting end. The cover portion covers
the LED of the lamp unit and is integrally formed with the elongated
portion. The light guide connects with the lamp unit at the cover
portion. The indicator lamp prevents rainwater from the top from entering
the lamp unit.
