Couple of quick questions regarding these bulbs. My electrical diagram shows using the 257 "blinking bulbs" in the "LIGHTS" warning socket and "BRAKE" warning socket of the dash cluster. Since these bulbs blink, I assumed that they would both blink. The Judging Guide then states that the BRAKE warning light (for the emergency brake) should NOT BLINK. Ok. So, does the BRAKE light only blink for brake line pressure (the second job of this light) and not Emergency Brake engagement? Just not sure how to interpret the text. Haven't put the re-conditioned cluster back in, so I wanted to get an answer before doing so. Thanks.

Re: 257 Blinking Bulbs in 67 Dash Cluster
If you check the AIM, you will see that the parking brake bulb has a different part number than the headlamp warning bulb. previous years used the same bulb. The electrical diagrams may not reflect the change, and the electrical diagram in the aim does not call out the bulbs at least in my copy. I believe there is also a list in the owners manual that would reflect the proper bulbs.Bill Clupper #618- Top

That's correct - for a '67, it's an 1816, same as the cluster illumination bulbs, as shown in the bulb chart in the Owner's Manual.- Top

Re: 257 Blinking Bulbs in 67 Dash Cluster
Thanks guys. Saved me from re-installing the cluster with the wrong bulb. Funny how items like electrical diagrams that are sold as correct can still have wrong information on them. I took the original 1816 bulb out of the socket thinking, what a dummy, this should be a 257 so it blinks. Guess who the real dummy was - me. Not the first time for that.- Top
