Abstract
An automotive signal lamp including a plurality of light emitting diodes arranged along an edge of a base plate disposed within a lamp chamber, a plus line connector formed of a web-like conductive material and extending in an alignment direction of the light emitting diodes, and a minus line connector formed of a web-like conductive material and extending substantially in parallel with the plus line connector, wherein a predetermined number of the light emitting diodes constitute one light emitting diode group, one lead connector of each of the light emitting diodes is integrally formed with one lead connector of the adjacent light emitting diode through a joint piece, an outer lead connector of one utmost light emitting diode of the light emitting diode groups connects to the plus line connector through the short-circuit piece, and an outer lead connector of the other utmost light emitting diode of the light emitting diode group connects to a minus line connector through a resistor which is provided to bridge over the plus line connector.
