After visiting every auto parts store in town, I did a search for this type of bulb. Dennis Kirk was the only one to have it in stock, and only had 2 left. I lucked out getting the last ones since they were the only type that would fit into a compact turn signal and my flasher relay required a higher wattage in order to flash (and not be steady)
There is more to a bulb than will it fit in the socket. I bought a 1989 GSXR 750 that came with the Lockhart Phillips flush mounted front directional many years ago. You need to find the correct 12V 23 Watt bulb otherwise the directional on that side will not flash. I looked all around locally and online and could not find the correct bulb until I check out Dennis Kirk. Not only did they have the correct bulb but they shipped it in a cardboard box so it did not get broken in transit. I'm so very happy as I was considering buying new directionals. Thanks once again Dennis Kirk.
