A gauge assembly includes a dial face with a scale indicative of a vehicle operating parameter. The dial face includes an opening proximate the scale and an illuminable tick mark that extends through the opening in the dial face with the tick mark being larger than the opening.
Opening claim text (preview).
What is claimed is: 1. A gauge assembly comprising: a dial face including a scale indicative of vehicle operating parameter, the dial face including an opening proximate the scale; an illuminable tick mark extending through the opening in the dial face, wherein the tick mark is larger than the opening; and wherein the opening includes a corner width across each end of the opening and a central portion having a central width that is smaller than the corner width. 2. The gauge assembly as recited in claim 1 , wherein the corner width is greater than a thickness of the tick mark. 3. The gauge assembly as recited in claim 1 , including a plurality of tick marks spaced apart and extending through a corresponding plurality of opening. 4. The gauge assembly as recited in claim 1 , wherein the opening comprises a perimeter having curved sides and curved ends. 5. The gauge assembly as recited in claim 1 , wherein the opening includes side lengths and a middle length with the middle length being less than the side lengths. 6. The gauge assembly as recited in claim 5 , wherein the tick mark includes a longitudinal length that is less than the middle length of the opening. 7. The gauge assembly as recited in claim 1 , wherein the opening includes four concave sides. 8. The gauge assembly as recited in claim 7 , including a light guide and each of the tick marks extend from the light guide. 9. The gauge assembly as recited in claim 8 , wherein the tick marks are integral portion of the light guide. 10. The gauge assembly as recited in claim 8 , wherein the light guide is supported on a non-visible side of the dial face. 11. A method of assembling a gauge assembly comprising: forming a dial face to include a scale indicative of an operating parameter and openings relative to the scale; and inserting a corresponding plurality of tick marks through each of the openings such that a portion of each tick mark is visible on the dial face, wherein each of the openings is smaller than the corresponding one of the plurality of tick marks to form an interference fit between the tick mark and the opening; and wherein the dial face is formed of a flexible material and sides of the opening bend upward responsive to receiving one of the plurality of tick marks. 12. The method as recited in claim 11 , wherein the opening comprises four concave sides and the tick mark bends the four concave sides outward when inserted through the dial face. 13. The method as recited in claim 12 , wherein the four concave sides press against surfaces of the tick mark. 14. The method as recited in claim 11 , wherein the plurality of tick marks are part of a light guide and inserting the tick marks into the openings aligns the tick marks and light guide relative the dial face. 15. The method as recited in claim 14 , including supporting a light source relative to the light guide to illuminate the tick marks.
