dear Exo,

pic B is correct then....
can i conclude that on the transistor...
the emitting (#1) will be triggered when signal is received on (#2)
Since the blub is currently parellel with the +ve taken from tapped wire on Vdd link (either frm Paking or Signal)... it WILL NOT LID the bulb unless it's triggered on #2 from the CMOS 4030.
Generally, the emitting side actually connects / link #3 to #1 if received signal frm #2 (on O1 of 4030) similarly like a NC/NO relay.

So when my parking light is ON, it will trigger 4030, send signal to the transistor and have my fender light ON as well. Trigger on I1.

"Truth table 1"
P F | F
-------
1 0 | 1

In the day-time when my parking light OFF, it will act normally as a signal light (fender). Trigger on I2.

"Truth table 2"
P F | F
-------
0 1 | 1

When my parking light ON (triggering "Truth table 1") and my signal light triggered, it will then goto "Truth table 3" which will OFF the bulb (fender light) and when the signal blinks OFF the bulb be activated. It will interloop between Truth table 1 and Truth Table 3 which in other words, will have the signal lights on the fender working opposite signal whenever a signal is triggered.

"Truth table 3"
P F | F
-------
1 1 | 0

Scenario... LEFT side.

When PARKING bulb OFF. Strike a SIGNAL... blinking
1. Front bulb - ON/OFF
2. Rear bulb - ON/OFF
3. Fender bulb - ON/OFF
- all as its blinking at an internal...

When PARKING bulb ON. Strike a SIGNAL... blinking
1. Front bulb = ON/OFF
2. Rear bulb = ON/OFF
3. Fender bulb = OFF/ON
- fender as in blinking opposite signal with the front and rear bulb.

I hope my explanation is clear -checkmate.
And Exo, can i achieve this without delay of opposite blinking signal / fender lights. Coz the used of a relay there's a certain delay but the used of CMOS delay is much lesser (milli secs.) as i was told.

Thanks bro Exo.
Hope i can find such transistor....

 

It's pretty much instantanious...
