C1 tail lights/turn signals

[Bud Landacre]

Owner's manual calls for 1034 bulbs in tail lights/parking lights in my 62. The car currently has 2057 bulbs installed with the exception of 1 1157 in the right rear. This particular turn signal is not as bright as the others. All turn signals flash more rapidly than I think they should. Will the bulbs effect the rate of flash?

Gettin ready to head to my FLAPS.
Thanks

Re: C1 tail lights/turn signals

Bulbs that draw greater current cause the thermal element in the flasher to heat more rapidly, speeding the cycle - bulbs with very low draw cause slow or no flash. Also, flashers do "tire out". Regards, ...Al '58 245hp

Re: C1 tail lights/turn signals

Thanks Al, I assumed higher resistance through the bulb would result in faster flashing. I guess I am asking if anyone knows what the difference in the resistance levels are between the 1157, 2057, and 1034 bulbs are.

Re: C1 tail lights/turn signals

According to my Sylvania Automotive Catalog 1034 draws 1.8 amps and 1157 & 2057 draw 2.1 amps at 12.8 design volts. Difference between 1157 and 2057 is 2057 is a long life bulb.
