Toyvo,

Have you finished your wiring deal yet? Did you install the adapter, and how does it work.

I did some mini-research on these things. It's a tad ambiguous, because they all seem to have a common name, but some do a completely different task.

The interesting one I saw was designed to work in your application (I think). It had circuitry that powered a single filament lamp with reduced voltage for taillights, then kicked it up when the brakes were applied, giving a much brighter light...faux dual filament!
