C1 | C2 60-67 T3 Headlight Bulb Set

Description

Great care was taken to improve the photometrics and candlepower of these bulbs in order to meet the current Federal Highway Safety and Lighting Standards, without compromising the original lens prescription.

1960-1967 Corvette headlight bulbs will fit, and be correct for, all 1960-67 GM vehicles with a 4 headlight bulb system using 5-3/4″ bulbs. Complete set includes (2) hi-low beam & (2) hi beam bulbs.

Factory Original bulbs were not designed to last 40-50 years. Over time these bulbs (even never used bulbs) develop cracks in the varnish (seal) on the back of the bulb. Once a crack develops, air can enter the bulb (which is under a sealed vacuum), and the filament will instantly burn out when power is applied.

In order for these T-3® headlight bulbs to be street legal and sold in the U.S.A., they had to be manufactured to meet or exceed the current U.S. federal highway safety and lighting standards. Consequently, T-3® Corvette bulbs are manufactured to be about 25% brighter than the original bulbs. They do not project the typical dim, yellow cast as the original bulbs did; leading to difficult night time driving. (For those of you who are concerned about having your car judged, the level of bulb “brightness” is not a judging criteria – but at least you’ll be able to see when you drive.) If you were to replace only one bulb, you would instantly notice the difference in brightness when placed side-by-side to an old original bulb.
