Why you shouldn't 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 (either used or N.O.S.) instantly or quickly burn-out?
The reason is simple. Original bulbs were not designed to last 50+ 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 when power is applied.

Why do we sell our bulbs in complete sets (not individually)?
If you were to replace only one your old bulbs with one of our new bulbs, you would instantly notice the difference when placed side-by-side. We want all of your headlight bulbs to have equal brightness, color and lens clarity.
