<P>PROBLEM TO BE SOLVED: To provide an LED marker lamp capable of reducing the difference in color tone from that of a bulb marker lamp within a range of adjustable brightness ratio. <P>SOLUTION: An LED marker lamp 11b is used in place of a bulb marker lamp 11a on a marker lamp system 10 which adjusts the brightness of the bulb marker lamp 11a to a predetermined brightness ratio. The LED marker lamp 11b has an LED element 25 for generating the light to irradiate the outside. The LED marker lamp 11b is preset so that the color tone of the light irradiating the outside at a brightness of an intermediate value within an adjustable brightness ratio matches with the color tone of the light from the bulb marker lamp 11a irradiating the outside at a brightness of an intermediate value with in the same range of the brightness ratio. <P>COPYRIGHT: (C)2013,JPO&INPIT |
