Anybody know of a source for 12V 21/6CP bulbs in amber color. These are fairly common in clear as they are used in most aftermarket cowl lights and park/turn applications. I have googled and searched here and found the following, "Try this place they have them, http://www.donsbulbs.com/cgi-bin/r/b.pl/1209.html". Unfortunately the website states Don has retired, and Dons bulbs is permanently closed. Thank You
If it's a standard base, you want either a 1157A or 1034A. The A stands for amber and most any parts house should have them... Be aware that if it's for a import, some of those use a odd size base that looks the same but isn't.

If that's what you're looking for, buy 'em by the dozen as these burn out rapidly. These are non-standard lamps designed to fit some aftermarket motorcycle lights and run very hot which is why they don't last (not enough surface area on the glass bulb to radiate the heat away). They've been known to melt plastic lenses, so keep that in mind. Most Harley shops should either have them or can get them for you...
