My '49 has an Allstate aftermarket blinker unit clamped onto the steering column. The blinkers do (barely) work at the rear, but they are very, very weak and they flash very rapidly. In contrast, the tail lights are very bright (as is the center brake light). Any thoughts on why the blinkers flash so weakly and rapidly, compared to how bright the tail lights are?
Based on some of the other threads I've read, it sounds like they probably never hooked up the front parking lights as blinkers - is that a valid assumption?
