LED Flasher Relay

[GoldOxide_imp]

Gold, My initial results are perplexing so before I do a good test and post some pics of the scope presentation I have to redo my test setup.

My initial test setup try ended up blowing the turn signal fuse. I then ran the test with the left front bulb removed. With ignition on, and thus the running lights on, I did not get the 4.5v. Instead it was a pulsed 12v. Interesting. With the Left signal selected I got the hyper flashing, but was a pulsed 12v as you would expect. And obviously a lot faster. 0v to 12v then back to 0v for non electronic guys. It appears that the running light intensity is not controlled by lowering the voltage, but by pulsing the 12v. Changing the duty cycle to about .5 Half on half off. We’ll see when I post scope pics.

I want to do the test with the lights operating normally so I am going to have to open up the headlight so I can get to the left signal connection for the 12v connection and have the bulb installed. Then there will be no hyperflashing and I can get exact operation.

Sounds like the circuit is behaving like in a variable pulse width modulated mode. That can control perceived illuminator brilliance, and in the case of some high-tech LEDs, colour or colour temperature (measured in Kelvin).

Gold, new test setup is done and everything works properly. I’ll finish the project tomorrow, get the pics transferred to Photobucket (yeah I pay for it—sue me) and get them here.

Just so non techs know, I will explain how to read an o’scope so you can understand what you are seeing. It is NOT rocket science. Easy really. Heck, I can do it

Sounds exciting LPG (not Low Pressure Gas).

Makes me wonder a bit how Honda did back in the early 1980s?
