An accent lamp (10) having a solid state light source (4), such as LEDs, is attachable to a rear surface of an automotive headlamp (40) opposite the light-generating capsule (44). Accent lamp (10) has first retaining member (20), such as a clamp, formed above printed circuit board (8) on which LED (4) is mounted. Headlamp base (60) defines light passageway (45), formed as a light guide (42), extending from outermost peripheral surface (63) to an upper surface (61) on which lamp capsule (44) is retained. Accent lamp (10) is readily detachably mounted to headlamp (40), preferably by resilient first and second retaining members (20, 24), and, when mounted, can be biased to promote optical coupling of light source (4) to light guide (42).

1. A combination automotive headlamp and an external attachable light source, comprising: a headlamp (40) comprising a lamp capsule (44) adapted to generate light;a headlamp base (60) including an upper surface (61), an outermost peripheral surface (63), a capsule lead-receiving region (64), and a vehicle wiring connector-receiving region (65);a retainer (54) affixed to the lamp capsule (44) and interconnecting the headlamp base (60) and the lamp capsule (44), the retainer (54) defining at least one light exit region (56) at a location between the upper surface (61) and the lamp capsule (44); andthe headlamp base (60) further defining a cavity (47) therein disposed underneath the lamp capsule (44) and defining a light passageway (45) extending between the outermost peripheral surface (63) and the upper surface (61), the light passageway (45) defining a light entrance window at the outermost peripheral surface (63); andan accent lamp (10) attachable to the automotive headlamp base (60), the accent lamp comprising a base (2);a solid state light source (4) disposed on the base (2); anda first retaining member (20) disposed on the base (2) and adapted to attach to a first portion of the headlamp base (60); whereby the solid state light source (4) is optically coupled to the light entrance window of the headlamp base. 2. The lamp combination of claim 1, wherein the first retaining member (20) comprises a flexible band. 3. The lamp combination of claim 2, wherein the flexible band comprises a cable tie. 4. The lamp combination of claim 1, wherein the first retaining member (20) is configured to be attachable and selectively detachable to the headlamp base (60). 5. The lamp combination of claim 1, wherein the accent lamp base (2) comprises a second retaining member (24) disposed on the base in spaced relation to the first retaining member (20), the first retaining member (20) being configured to attach to an outer surface of the capsule lead-receiving region (64) of the headlamp base (60), andthe second retaining member (24) being configured to attach adjacent the vehicle wiring connector-receiving region (65). 6. The lamp combination of claim 5, wherein the capsule lead-receiving region (64) and the wiring connector-receiving region (65) are generally perpendicular one another. 7. The lamp combination of claim 1, wherein the first retaining member (20) is resiliently supported relative the base (2) on which it is disposed, whereby, in a condition of the accent lamp (10) being attached to the headlamp (60), the solid state light source (4) is biased towards the light entrance window. 8. The lamp combination of claim 1, wherein the accent lamp base (2) comprises a second retaining member (24) disposed on the base in spaced relation to the first retaining member (20); andthe first retaining member (20) and the second retaining member (24) each comprising clamps having respective openings defining respective headlamp introduction passageways (28, 30), the passageways being generally aligned, thereby facilitating a generally lateral introduction of the accent lamp (10) onto the headlamp (40). 9. The lamp combination of claim 1, wherein the lamp capsule (44) comprises a press seal end (52) with at least one electric lead (48) extending through the press seal (52), and the retainer (54) is affixed to the press seal end (52). 10. The lamp combination of claim 1, wherein the solid state light source (4) further comprises a collimating lens (6). 11. The lamp combination of claim 1, wherein the headlamp base (60) conforms to a spatial envelope of a lamp chosen from the group of lamps consisting of the types SAE-9005, SAE-9006, SAE-9145, SAE-9140, SAE-9155, SAE-9040, SAE-9045, SAE-9055, EC-HB3, EC-HB4, and EC-HB10. 12. The lamp combination of claim 1 in combination with an accent lamp (10) comprising a solid state light source (4) disposed on a substrate (8) provided with electrical traces, the accent lamp (10) being coupled to the outermost peripheral surface (63) and configured to direct light emitted from the accent lamp (10) into the light passageway (45). 13. The lamp combination of claim 1, further comprising a controller coupled to a power supply to adjust at least one of a light color and a light intensity provided from the solid state light source. 14. A method of attaching an accent lamp to an automotive headlamp, comprising: providing a headlamp (40) comprising a lamp capsule (44);a headlamp base (60) defining an upper surface (61) to which the lamp capsule (44) is retained, the headlamp base (60) further defining a light passageway (45) therethrough extending from a light entrance window located at an outermost peripheral surface (63) of the headlamp base (60) to a light exit at the upper surface (61);providing an accent lamp (10) comprising a solid′state light source (4) disposed on a base (2);positioning the accent lamp (10) external the headlamp base (60); andorienting an emission region of the solid state light source (4) towards the light entrance window. 15. The method of claim 14, further comprising biasing the solid state light source (4) to the light entrance window. 16. The method of claim 14, further comprising providing first and second retaining members (20, 24) on the accent lamp base (2), the second retaining member (24) being spaced from the first retaining member (20), each retaining member (20, 24) being adapted to attach to respective regions of the headlamp base (60);biasing the first retaining member (20) relative the base (2) of the accent lamp (10);attaching the second retaining member (24) to the headlamp base (60); andattaching the first retaining member (20) to the headlamp base (60) and thereby urging the accent lamp (10) toward the headlamp base (60). 17. The method of claim 14, further comprising providing first and second retaining members (20, 24) on the accent lamp base (2), the second retaining member (24) being spaced from the first retaining member (20), each retaining member (20, 24) having respective openings defining respective headlamp introduction passageways (28, 30), the openings being aligned in generally a common direction; andattaching the first and second retaining members (20, 24) to the headlamp base (60) comprises introducing the headlamp generally laterally toward the headlamp introduction passageways (28, 30). 18. The method of claim 17, wherein the lamp capsule has a capsule major longitudinal axis (O), andthe introducing the headlamp laterally comprises laterally moving generally perpendicular to the capsule major longitudinal axis. 19. The method of claim 17, wherein the lamp capsule has a capsule major longitudinal axis (O), andthe introducing the headlamp laterally comprises laterally moving generally parallel the capsule major longitudinal axis.
