Hi,
I bought and installed the Sealight HB5 9007 LEDs in place of my quartz halogens yesterday in my 1932. Great light and cut off. No flicker and instant high/Low light change without delay. I checked them within my garage for the cutoff. I don't drive the 32 at night but will give it a try. I wanted them for daytime visibility and less amperage than the quartz.
The instructions included were lacking but found a video online after the fact.

Glad I made the switch to LEDs.
