Turn signal flicker question
Wednesday, September 30, 2009 2:18 PM
Correct me if i'm wrong, but our BCM works like this. Place a filament bulb in a turn signal socket and it flicker normally. When the bulb breaks, it triggers a signal that "bulb is broken" and as a result it flickers quicker. Now my question to the J-body electronic gurus, how low of a wattage does BCM need to trigger "bulb is broken?"
Looking for some LEDs and they are high-powered and maybe I can avoid adding a consumer or run the stock bulb in parallel.

Thanks.

just get a led replacement flasher. they're the same price as our stockers, just don't have the blown bulb telltale. the bcm doesn't control the quick flashing, the flasher does.

Rich, I think you may have saved my day man.

-Do you mean something like this?

-If so, is that the model that I need?
-By any chance, would you know where this flasher goes?
-And lastly, this will not let it draw out more power correct, all it does is accepts LED bulbs correct?

That's what we need for our cars.




Your car may do 13 sec @ 103 mph, but my car does 146db @ 35 hz.
