Taillight Bulbs - 1158??

Posted by Joe On 2024/2/16 20:28:02
Hey all... silly question here. Been slowly re-working a lot of my wiring (many thanks to Howard for the wiring chart) on my '50, which remains 6v positive ground. One of the silly trivial things I thought I would do is update some of the exterior lights to LEDs. I bought amber-colored 1154 bulbs for the signal flasher/parking lights along with 6v flasher for LEDs. These are outstanding and work great.

The curiosity is the 1158s. This is of course what the manual defines as the taillight bulb. On top of not lighting at all, the bayonets on the LEDs were parallel, while the sockets in my 23rd require offset bayonets. I've also received incandescent 1158s that are also parallel. What am I missing here? Do 1158s come with different bayonet setups, should I be using a different bulb. The incandescents I have in there right now work well, but they are, of course, not labeled beyond their voltage, so I'm not certain of what they are (I THOUGHT I remembered putting 1158s in there... maybe not?) Definitely missing something. Thanks, all.
