As most of you know, the tail lamps on American vehicles act the the rear indicator. Flashing red lights are not road legal in the UK and Ireland (at least if the vehicle is newer than 1969 in UK). We found a nice little dual colour LED bulb to carry out our Roadrunner rear indicator conversion.
The bulb fits into a stop tail bulb holder. I got a matching pair of bulb holders of a Honda CBR. I had to cut the original bulb holder out the lamp housing and bond in the new ones. Once done, the reverse lamp functions as the indicator. A lot neater than bold on lamps, let us know your thoughts.
