Why shouldn't you buy an old/original bulb (used or N.O.S.)?
If you were to buy an N.O.S. (new old stock) bulb from a vendor at a swap meet, the going price per bulb would almost equal what we charge for our complete set. And what the vendor doesn't tell you is that when you go to energize your newly purchased N.O.S. bulb, it may instantly burn out, or is certainly destined for a very short life. Obviously, this is also true of bulbs purchased from a junk yard.
Why will an old/original bulb (used or N.O.S.) instantly or quickly burn-out?
The reason is simple. These bulbs were not designed to last 40+ years. What will happen to these bulbs (even un-used bulbs) is that over time they can develop very minute cracks in the varnish seal on the back of the bulb and adjacent to the terminal posts. Once a crack or gap in the varnish seal occurs, air can enter the bulb (which is under a sealed vacuum), and the filament will instantly burn out if power is applied.
Why do we sell our bulbs in complete sets (not individually)?
In order to manufacture our T-3 bulbs, we had to meet the current federal lighting standards. Consequently, our T-3 bulbs are brighter than the original bulbs. They do not project the typical dim, yellow cast as the original bulbs did which lead to difficult night time driving. (For those who are concerned about having your car judged, the level of bulb "brightness" is not a judging criteria.) If you were to replace only one bulb, you would instantly notice the brightness difference when placed side-by-side to your original bulb.
