Hello, I can't tell you how many tail and parking light bulbs I have changed over the years. The new numbers are not listed by the old numbering system. I know I'm suffering from a slight case of coma or worse. On our old pre 1955 six volt trucks what is the tail/brake light numbers and parking light numbers? Is the tail light 1156 and the park..... oh heck! You tell me please. Doc.
