How many bulbs?

[Bill I.]

How many 1816 bulbs light the clock, and how many 1893 bulbs light the heater control panel? Thanks, Bill. PS it's a 67.

There are two bulbs for the clock, and one for the "torpedo" lamp that illuminates the heater control bezels (on a non-A/C car).

1968 dashs and it identifys the 1895 bulb for the clock , 1145 bulb for the heater control panel , and the 1893 bulb for the radio dial lamp . Please help me if this is not correct. thanks

Yes, the # 257 blinker bulbs were used for HL door and parking brake warning applications. Crack open your copy of the car's Owners Manual or, if you have it, the 1965 Corvette Shop Manual. Both provide a list of what lamps were used where...

Jack,

Brake lite warning does not flash in 1967, only the headlite bucket warning. This change was due to the incorporation of the hydraulic brake system malfunction warning introduced in 1967

In 67:
Flashing bulb #257
Brake warning bulb #1816

Ditch the Chilton's book and use GM references (like the bulb chart in your owner's manual).

Steve, THANKS for keeping me honest! I tend to forget that '67 was an exception to the rule on # 257 blinker bulb useage...
