I am confusing about the rate of diode's amp for making signal-light-flash by parking-light-flash wire of the brain. This must be basic of you all. I apologize to my unpolished knowledge.

To flash both signal lights, insted of parking light, I'm using relay to block countercurrent as follows,

But next next time I will install, I want to use 2diodes as follows,

Then my question is, how much amp does the diodes need, 1A or 6A? The curent from the brain, anode, is 200mA. But signal lights,cathode, is about 4-5A. Which one do I have to do? Thank you in advance.

You should use Relays.............if your Parking Light Output is only 200mA

Thanks. But I had a MISTAKE!!!

The amp of parking light output(+) is NOT mentioned on the manual. Actually, I'm looking at the manual of Viper550ESP. On that, "H1/2WHITE" wire is "(+)/(-)selectable light flash output" and it is when (-) selected that 200mA output. When (+) selected, this wire can connect to the (+)parking light wire, which means it is able to connect (+)signal light wire?

Should be...........
If U are just using the FLASHING Output, then 1amp Diode will work.
If it is CONTINUOUS (on all the time) use the 6 amp Diodes.
Either will work

200mA output is when selected (-) control. I want to flash both left and right bulbs by (+) output whichi is able to power directly.
