I've played guitar for almost 50 years now and a friend gave me an old "Gibson" guitar sign that must have hung in a music store sometime in the last 30 years. This hard to find bulb was easy to find at bulbs.com! Thanks!

I ordered the wrong size bulbs. Bulbs.com sent my order quickly, and well packed. When I had to return (due to my error) the customer service agent was polite, and helpful. Will keep you in mind for future bulb orders (around the house), and for recommendations to friends. Thanks!

Is bulb length measured by just the bulb or from the ends of the bi pins?
